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