WebAn AC motor is a motor that converts alternating current into mechanical power. The stator and the rotor are important parts of AC motors. The stator is the stationary part of the motor, and the rotor is the rotating part of the motor. The AC motor may be single-phase or three-phase. Nikola Tesla invented the first AC induction motor in 1887.
WebAug 30, 2024 · The disadvantages of a 3-phase induction motor are given as follows −. The 3-phase induction motors are constant speed motors; hence their speed control is very difficult. 3-phase induction motors have poor starting torque and high inrush currents (about 4 to 8 times of the rated current). They always operate under lagging power factor … chest tube after vatsWebMar 2, 2024 · A single-phase commutator-type motor with a wound rotor and brush configuration is known as a repulsion motor.
