Grounding a 3 hase induction motor
WebAbstract: This paper presents a phase to ground leakage current in 3-phase induction motor caused by switching voltage source. The phase to ground leakage current of induction motor is effected by impedance of motor insulator which varied with switching frequency from voltage source. WebMar 12, 2024 · 3-phase AC induction motors are comprised of the stator and rotor. During operation, a current is applied through the stator, which induces a magnetic field and leads to the rotation of the rotor. The rotational speed of the shaft and the applied torque are dependent on the operating frequency and the number of pole pairs in the motor’s …
