Trivia Quiz About Three Phase Motor - Quiz

A three-phase motor is an electric machine that is powered by three phases of electricity. Three phase motors are mostly used in industries and post lumbering works. The three phases of currents powering this motor do not cross each other and are converted mechanical energy as the motor rapidly rotates.
