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

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