Tell me about the working principle of single-phase motor

Classification:

Single-phase motor, refers to the 220V AC single-phase power supply and operation of asynchronous motor. Since the 220V power supply is very convenient and economical, and the household electricity is 220V, the single-phase motor is not only used in consumption, but also closely related to people's daily life, especially with the increasing progress of people's life and death level, the consumption of single-phase motors for household appliances is also increasing.

In terms of consumption, there are micro water pumps, refiners, threshing machines, pulverizers, woodworking machinery, medical equipment, etc., in terms of life, there are electric fans, hair dryers, exhaust fans, washing machines, refrigerators, etc., with more varieties, but less power. When a single-phase sinusoidal current is passed through the stator winding.

The motor will produce an alternating magnetic field, the strength and direction of the magnetic field from time to time sine law changes, but in the spatial orientation is fixed, so also known as the magnetic field is alternating pulsating magnetic field. This alternating pulsating magnetic field can be synthesized into two rotating magnetic fields with the same rotation speed and opposite rotation directions.

When the rotor is stationary, these two rotating magnetic fields generate two torques of equal magnitude and opposite directions in the rotor, making the combined torque zero, so the motor cannot rotate. When we use an external force to make the motor rotate in a certain direction (such as clockwise rotation), then the rotor and the rotating magnetic field in the clockwise rotation direction between the cutting magnetic line movement becomes smaller.

How to store, transport and anti-corrosion measures for high-lift deep well pumps For well pumps containing packed wooden boxes, they should be placed on a flat concrete floor. For deep well pumps without packed wooden boxes, they should be discharged flat on the pump rack with 3 support points. Both sides shall not be suspended in the air for more than 1m.
