The advantages of air compressor asynchronous motor over traditional permanent magnet motor

The asynchronous motor is a three-phase induction motor, not the rare earth permanent magnet motor used in traditional electric vehicles. What are the reasons for this? The difference between induction motors and permanent magnet motors.

　　 The induction motor is an asynchronous motor. It is an AC motor that generates an electromagnetic torque to drive the rotor to rotate by interacting with the rotating magnetic field formed by the stator winding and the magnetic field of the induced current in the rotor winding.

　　Asynchronous motor advantage 2: The output torque of the induction motor can be adjusted in a wide range, so there is no need to install the second or even the third set of transmission mechanism. The motor speed designed by Tesla can reach 6000 revolutions per minute and can produce a torque of up to 400 Newton meters. It can forcibly increase the output torque when accelerating or climbing (although the time is short), while the permanent magnet motor electric vehicle needs Through the gear box to output more torque to achieve speed.
