Where: V L is the line-to-line voltage, and V P is the phase-to-neutral voltage.A transformer can not act as a phase changing device and change single-phase into three-phase or three-phase into single phase.The third difference we want to mention here is that the

The three phase motor is widely used in industry because of it's low maintenance characteristics. Due to the nature of three phase power, creating a rotating magnetic field in the stator of this motor is simple and straight forward. The strength of the magnetic field changes, as the current flow in the coils of wire around the stator poles change.

The three-phase AC motor with motec is a new integrated solution. Our three-phase AC motors are particularly suitable for inverter operation. Modern inverters switch power stages at switching frequencies between 4 and 16 kHz, which can give rise to high rates of voltage rise and overvoltages in the motor windings.
