Most pumps and supporters operating in commercial 
and industrial applications are driven by AC induction motors. “ACIM”, which stands for “alternating electric current induction motor”, is an asynchronous type of motor that relies on electric current to 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 always rotates at a lower speed than the magnetic field. A “PMSM”, which stands for “permanent permanent magnet synchronous motor Magnet synchronous engine”, depends on magnets to turn the rotor, which spins at the same velocity as the PMSM’s inner rotating magnetic field.
There are some key differences between AC induction Motors and Permanent Magnet Synchronous Motors.
