Most pumps and enthusiasts operating in industrial and industrial applications are currently driven by AC induction motors. “ACIM”, which stands for “alternating electric current induction motor”, is an asynchronous kind 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 produced 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 means “permanent permanent magnet synchronous motor Magnet synchronous electric motor”, depends on magnets to turn the rotor, which spins at the same acceleration as the PMSM’s internal rotating magnetic field.
There 
are a few key differences between AC induction Motors and Permanent Magnet Synchronous Motors.
