Description

Ny motera induction phase generally refers to the single-phase ac power supply (AC220V) supply of small power Split phase induction motor. The motor usually has a two-phase winding on the stator and a common squirrel cage rotor. The distribution of two-phase winding on stator and the difference of power supply can produce different starting and running characteristics.

In the production aspect application has the miniature water pump, the pulverizer, the thresher, the crusher, the woodworking machinery, the medical treatment apparatus and so on, in the life aspect, has the electric fan, the hair dryer, the exhaust fan, the washer, the refrigerator and so on, the kind is many, but the power is small for Ny motera induction phase.

Single-phase motor, refers to by 220V ac single-phase power supply and operation of the asynchronous motor.Because 220V power supply is supplied very convenient economy, and domestic life USES electricity to also be 220V, so single-phase motor is not only in production dosage is big, and also with people daily life, close concern, especially as the people's living standard is raised increasingly, the dosage of single-phase motor of household appliance equipment, also more and more.

In the production of the application of miniature water pump, grinder, thresher, crusher, woodworking machinery, medical equipment, in life, there are fans, hairdryer, exhaust fan, washing machine, refrigerator, more kinds, but smaller power.

Working Principle

When the sinusoidal current of the single phase passes through the stator winding, the motor will generate an alternating magnetic field FIG. 2 wiring diagram and vector diagram of capacitance split-phase motor FIG. 2 wiring diagram and vector diagram of capacitance split-phase motor.

The intensity and direction of the magnetic field of Ny motera induction phase vary sinusoidal law at any time, but it is fixed in the spatial orientation, so it is also called the alternating pulsating magnetic field. This alternating pulsating magnetic field can be decomposed into two rotating magnetic fields with the same speed and opposite rotation direction.

The strength and direction of a magnetic field change sinusoidal at any time, but it is fixed in the orientation of space, so it is also known as the alternating pulsating magnetic field.This alternating pulsating magnetic field can be decomposed into two rotating magnetic fields with the same rotation speed and opposite rotation direction. When the rotor is stationary, the two rotating magnetic fields will generate two equal and opposite torque in the rotor, making the resultant torque zero, so the motor cannot rotate.When we use external force to make the motor rotate in a certain direction (such as clockwise rotation), then the movement of the cutting magnetic force line between the rotor and the rotating magnetic field in the clockwise rotation direction becomes smaller.The movement of the cut magnetic field line between the rotor and the rotating magnetic field in the counterclockwise direction becomes larger.The balance is broken, and the total electromagnetic torque generated by the rotor is no longer zero.

To enable the single-phase motor to rotate automatically, we can add a starting winding in the stator. The starting winding is 90 degrees different from the main winding in space. The starting winding should be connected with a suitable capacitor in series, so that the current is approximately different from the main winding in phase

90 degrees, the so-called phase separation principle.So two currents that differ by 90 degrees in time flowing into two windings that differ by 90 degrees in space will generate a rotating magnetic field in space,

Under the action of this rotating magnetic field, the rotor can start automatically. After starting, when the speed rises to a certain level, the starter windings will be disconnected with the help of a centrifugal switch or other automatic control device installed on the rotor. Only the main windings will work in normal operation.Therefore, the starting winding can be made to work for a short time.However, there are many times when the starting winding is not disconnected. We call this motor a single-phase motor. To change the direction of this motor, just change the terminal head of the auxiliary winding.

In single-phase motors, another method of generating rotating magnetic field is called the hood method, also known as single-phase hood motor.This type of motor stator made of salient pole type, there are two poles and four poles.Each pole has a small slot at 1/3 ~ 1/4 full pole surface, which divides the pole into two parts. A short circuit copper ring is set on the small part, which seems to cover this part of the pole.The single-phase winding is set on the whole magnetic pole. The coil of each pole is in series. When connected, the polarity generated must be arranged in N, S, N and S sequence.When the stator winding current in the magnetic main flux, according to lenz's law, which through the short circuit copper ring main magnetic flux in the copper ring produces a 90 degrees on the phase lag of the induced current, flux on the phase of the current and lag behind the main magnetic flux, its role and the capacitor motor starting winding, motor rotation to produce a rotating magnetic field.

Theoretically, if measures are taken to make the ac current flowing through the windings of the Ny motera induction phase have a certain phase difference, it can be started. How to make certain phase difference between magnetic potential or magnetic flux with certain Angle staggered in two Spaces is the starting point to solve the startup problem. According to this, the single-phase ac asynchronous motor can be divided into two categories: phase-divided and pole-covered.

Single phase motor classification editing

Theoretically, if measures are taken to make the ac current flowing through the two sets of windings of the single-phase motor have a certain phase difference, it can be started.How to make a certain phase difference between the magnetic potential or magnetic flux with a certain Angle staggered in two Spaces is the starting point of solving the boot problem.According to this, the single phase ac induction motor can be divided into two categories: phase type and cover type.

Split phase single phase motor

Phase splitting single-phase motor USES capacitance or resistance to stagger the current phase of the start winding and the work winding, which is called "phase splitting".

(1) capacitor phase split single-phase motor

Figure (a) shows the principle wiring of the capacitor phase split single-phase motor.Due to the obvious phase shifting action of capacitor, as long as the capacitor with appropriate capacity is connected in the starting winding (generally about 20 ~ 50 muon F), the current phase difference between the two windings can be close to 90°. At this time, the synthetic rotating magnetic field is close to the circular rotating magnetic field, so the starting torque is large while the starting current is small.These single-phase motors are commonly used and can be retained or removed as needed after starting (called capacitive start motors) or removed (called capacitive start motors, executed by centrifugal switches placed inside the motors).If it is necessary to change the direction of the motor, just switch the outgoing end of any winding, at which time the current phase relationship of the two windings is opposite.

Split phase single phase motor

(2) resistor phase splitting single-phase motor

This kind of motor start winding has fewer turns, thin wire, small reactance and large resistance compared with the running winding.When the resistance phase separation is adopted for starting, the current of the starting winding is ahead of the running winding, and the synthetic magnetic field is an elliptical rotating magnetic field with larger ellipticity. The starting torque is small, and it is only used for no-load or light-load occasions, with few applications.The start windings of the single-phase electric motor of the resistance split-phase type are generally designed for short-time operation. After starting up, the windings are removed by the centrifugal switch and maintained in operation by the working windings.Figure (b) shows the principle wiring of the resistor phase split single-phase motor.

Cover type single phase motor

A single-phase motor with a cover electrode is formed by embedding a portion of the stator magnetic pole with a short circuit copper ring or a short circuit coil (group).The single phase motor with cover pole includes salient pole type and implicit pole type.

When the stator winding passes through the single-phase ac current, most of the pulse vibration magnetic field generated by it is directly coupled to the rotor through the air gap, while a small part of the flux is generated through the copper ring of the cover pole and synthesized with it and enters the rotor magnetic circuit through the air gap.According to lenz's law, the induced magnetic flux always hinders the change of the original magnetic flux, and the phase of the induced magnetic flux lags behind the original magnetic flux.In this way, there are two magnetic flux which stagger in space at a certain Angle and have a certain phase difference. The synthetic magnetic field is a rotating magnetic field with great ovality.The rotation direction of the motor is fixed from the uncapped part to the capped part, which has smaller power, small starting torque, simple structure, low price and easy maintenance.Cover type motor is generally used for small blower motor and fan motor.

Start mode editing

1.Start the way

Starting mode of 220v ac single-phase motor can be divided into the following types:

The first, phase splitting, as shown in figure 1, is assisted by an auxiliary start winding.The starting torque is small.The rate of operation remains roughly constant.Mainly used in electric fans, air conditioning fan motors, washing machines and other motors.

Starta Method

220v ac Ny motera induction phase can be started in the following ways:

The first type, split phase start-up, as shown in figure 1, is assisted by auxiliary starting windings. Its starting torque is small. The running speed remains roughly constant. Mainly used in electric fans, air conditioning fan motors, washing machines and other motor.

Second, when the motor is stationary, the centrifugal switch is switched on. After the power is given, the capacitor is started to participate in the starting work. When the rotor speed reaches 70% ~ 80% of the rated value, the centrifugal switch will automatically jump, start the capacitor to complete the task and be disconnected.The starting winding does not participate in the operation, and the motor continues to operate with the winding coil, as shown in figure 2.

Figure 2 capacitive start wiring circuit

Third, when the motor is stationary, the centrifugal switch is switched on. After the power is given, the capacitor is started to participate in the starting work. When the rotor speed reaches 70% ~ 80% of the rated value, the centrifugal switch will automatically jump, start the capacitor to complete the task and be disconnected.The operating capacitor is connected to the starting winding in series to participate in the operation.This connection method is generally used in the air compressor, cutting machine, woodworking machine tools and other load large and unstable place.Jereo ny sary 3.

Figure 3 capacitor start operation transition wiring circuit

Motor with centrifugal switch, if the electricity can not be started successfully in a very short time, then the winding coil will be burned quickly.

Capacitance: the double-value capacitor motor has a large starting capacity and a small operating capacity, and its voltage resistance is generally greater than 400 V.

2.Positive and negative rotation control:

Figure 4 is the wiring diagram with a positive and negative switch. Normally, the starting windings of this motor and the running windings have the same resistance value, that is to say, the starting windings of the motor and the running windings have the same line diameter and coil number.This motor is commonly used in washing machines.This forward and backward control method is simple and does not need complex switch.

Figure 4 switch control positive and negative connection

Figure 1, figure 2, figure 3 reverse rotation control, only need to adjust 1 ~ 2 lines or 3 ~ 4 lines to complete the reversal.

As for the judgment of starting and running winding in figure 1, figure 2 and figure 3, the starting winding usually has a much larger dc resistance than the running winding, which can be measured by multimeter.Generally, the dc resistance of the winding in operation is several ohms, while the dc resistance of the starting winding is ten to ten ohms.[2]

Use and model editing

Because Split phase induction motor only needs single-phase power supply, it is widely used in production, life and other small equipment.But because of its all sorts of economic performance index are poorer, make small power only accordingly.

China's production of low-horsepower Split phase induction motors, there are several models.

1.BO2 series single phase resistance start induction motor.The power is between 60 and 370W.The feature is that, without any additional split-phase components, the secondary winding is started with its own resistance, and the secondary winding is cut off at the end of starting with a centrifugal switch.The structure is simple.It has medium starting torque and overload capacity, so it is suitable for small machine tools, blower, medical machinery.

2.CO2 series single phase capacitor start induction motor.The power is between 120 and 750W.It is a single - phase motor which is started by increasing the starting torque by applying extra capacitance.In the secondary winding, the additional capacitor is added in series, and at the end of starting, the secondary winding and the capacitor are removed from the power source together with a centrifugal switch. Like the BO2 type, the secondary winding is left idle while the primary winding is in operation.Capacitor starting motor has high starting torque, but medium overload capacity.Suitable for air compressor, refrigerator, washing machine, mill, thresher, water pump.

3.DO2 single-phase capacitor motor.It is a single-phase motor which USES a capacitor to start and run. The secondary winding and the capacitor and the main winding participate in the operation.Therefore, no centrifugal switch is required.Through appropriate design, the motor can form an ideal rotating magnetic field when running, so the motor has good running performance, high efficiency and power factor, and low noise.Its power range is 4 ~ 250W.Due to a capacitor is used to both the starting and operation, weigh the brake disadvantages due to the starting time is short, only when choosing capacitance value, try to meet the needs of longer runtime, cheap small value capacitors are selected, so this kind of motor starting torque is low, can only be used in the no load or light load starting of machinery, such as wind electric iron, ventilation fans, tape recorder, etc.

4.Double-value capacitor motor this kind of motor has no official model in our country at present, but also in production.The maximum motor power is 750W, or about 1kW.There are more powerful ones abroad.Due to the high power, the required capacitors are much more expensive.The motor has good starting performance and running performance.Words used in household appliances, small machine tools.

Maintenance Method

Professional motor maintenance maintenance center motor maintenance process: cleaning rotor, to replace carbon brush or other parts, vacuum F pressure paint, drying, dynamic balance adjustment.The environment should be kept dry, the motor surface should be kept clean, the air inlet should not be hindered by dust, fiber and so on.

The Ny motera induction phase should be well lubricated during operation. General motor operation about 5000 hours, that is, should be supplemented or replaced grease, running found bearing overheating or lubrication deterioration, hydraulic timely change grease. When replacing the grease, the old lubricating oil shall be removed, and the oil groove of the bearing and bearing cover shall be cleaned by gasoline.
