10. Starting Method for Induction Motors
www.uotechnology.edu.iqTherefore, 3-phase induction motors employ a starting method not to provide a starting torque at the rotor, but because of the following reasons; 1) Reduce heavy starting currents and prevent motor from overheating. 2) Provide overload and no-voltage protection. There are many methods in use to start 3-phase induction motors. Some of the common ...

POWERFACTOR CORRECTION (pfc)
electrical.theiet.orgConsider a single-phase induction motor. If the motor presented a purely resistive load to the supply, the current flowing would be in-phase with the voltage. This is not the case. The motor has a magnet and the magnetizing current is not in phase with the voltage. The magnetizing current is the current that
