How does the Centrifugal compressor Motor work?

When current passes through the stator winding of the motor, a rotating magnetic field is generated. This rotating magnetic field rotates inside the stator at a synchronous speed.
The rotor winding induces an electromotive force in the rotating magnetic field and generates current. Due to the interaction between the magnetic field and the current, the rotor is subjected to an electromagnetic force, which generates torque and causes the rotor to rotate at a speed slightly lower than the synchronous speed following the rotating magnetic field.
In the combination of the Centrifugal compressor Motor and the centrifugal compressor, the motor drives the impeller of the compressor to rotate at a high speed.
The impeller does work on the gas, causing the gas to gain kinetic energy and pressure energy. The gas is thrown to the edge of the impeller under the action of centrifugal force, and the kinetic energy is converted into pressure energy through components such as the diffuser and the volute, thereby achieving gas compression and transportation.
