Most pumps and followers operating in commercial and commercial applications are driven by AC induction motors. “ACIM”, which means “alternating current induction motor”, is an asynchronous kind 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 permanent magnet synchronous motor compared to the magnetic field. A “PMSM”, which means “permanent magnet synchronous engine”, depends on magnets to turn the rotor, which spins at the same quickness as the PMSM’s internal rotating magnetic field.
There are some key differences between AC induction Motors and Permanent Magnet Synchronous Motors.
