Different types of Induction Motor

Different types of Induction Motor SINGLE PHASE INDUCTION MOTOR 1.    Split phase induction motor There are various types of self-starting motors, known as split phase motors. Such motors have a starting winding displaced 90 electrical degrees from the main or running winding. In some types, the starting winding has a fairly high resistance, which causes the current in this...

Why LT motors are delta connected and HT motors are star connected?

Why LT motors are delta connected and HT motors are star connected?There is both reason technical and commercial. 1.     In star, phase current is same as line current. But phase voltage is 1/1.732 times line voltage. So insulation required in case of HT motor is less. 2.     The starting current for motors is 6 to 7 times full load current. So start-up...
