Most pumps and fans permanent magnet synchronous motor operating in commercial and industrial applications are currently MTHdriven by AC induction motors. “ACIM”, which means “alternating electric current induction motor”, is an asynchronous type of motor that depends on electric current to carefully turn the rotor. Torque is definitely produced by electric current in the rotor. The electric energy is generated through electromagnetic induction from the magnetic field of the stator windings. In an ACIM, the rotor at all times rotates at a lower speed compared to the magnetic field. A “PMSM”, which stands for “permanent magnet synchronous electric motor”, relies on magnets to carefully turn the rotor, which spins at the same quickness as the PMSM’s inner rotating magnetic field.

There are a few key differences among AC induction Motors and Permanent Magnet Synchronous Motors.
