Most pumps and supporters operating in commercial and commercial applications are driven by AC induction motors. “ACIM”, which means “alternating permanent magnet synchronous motor 
electric current induction motor”, can be an asynchronous type of motor that relies on electric current to turn the rotor. Torque is certainly produced by electric current in the rotor. The electric current is generated through electromagnetic induction from the magnetic field of the stator windings. Within an ACIM, the rotor often rotates at a lower speed compared to the magnetic field. A “PMSM”, which stands for “permanent magnet synchronous motor”, depends on magnets to turn the rotor, which spins at the same rate as the PMSM’s inner rotating magnetic field.
There are a few key differences among AC induction Motors and Permanent Magnet Synchronous Motors.
