Motors • 3 Phase Motors

3 phase motors are commonly used by electric power distribution grids to distribute power.

Typically more economical than single-phase and two-phase electric motors, three-phase motors deliver power continuously while using less conductor material to transmit electric power. When compared to single-phase motors of the same voltage class and rating, three-phase motors are more compact and vibrate less – resulting in a longer operating life.AC induction motors and synchronous motors - including steppers motors - often feature three-phase design.Three-phase AC induction motors are known for their simple design, and high starting torque and efficiency. Industrial pumps, fans, blowers, compressors, conveyor drives, and electric vehicles all utilize three-phase induction motors.Three-phase AC synchronous motors are used as traction motors and within power factor correction schemes. Some three-phase motors are explosion proof or designed to handle severe-duty applications.
