Frequency AC Motor

Frequency AC Motor is a common AC motor that controls speed by changing the frequency of the input power supply. This type of motor is often used in applications that require adjustable speed operation, such as fans, pumps, and conveyors. Frequency AC Motor usually consists of two parts: the stator and the rotor. The stator is the fixed part, which usually includes windings and an iron core, while the rotor is the rotating part, which is usually made of permanent magnets or copper.

Frequency: variable frequency operation

The working principle of this motor is based on the interaction of magnetic fields. When current passes through the stator winding, a rotating magnetic field is generated in the stator. This magnetic field interacts with the magnetic field in the rotor to generate torque, which drives the rotor to rotate. By changing the frequency of the input power supply, the frequency of the rotating magnetic field in the stator can be changed, thereby controlling the speed of the motor.
