Introduction to Induction Motors

Induction motors are also called asynchronous motors i.e., the machines which never run at a synchronous ______

These motors have low starting torque (1.5 to 2 times the full-load torque) with large starting current (5 to 9 times the full-load current). Their power factor is also ______

Induction motors may be single-phase or ______

Almost more than 90% of the mechanical power used in industry is provided by ______ phase induction motors

AC Motors 1- Single Phase A- Induction Motors i- Split Phase In. Motors ii- Shaded Pole In. Motors iii- Capacitor start ______

Three phase induction motors are the most commonly used AC motors in the industry because they have simple and rugged construction, low cost, high efficiency, reasonably good power factor, self-starting and low maintenance cost. Almost more than 90% of the mechanical power used in industry is provided by ______ phase induction motors.

During starting, there is more ______ loss

Induction motors are also called asynchronous motors i.e., the machines which never run at a synchronous speed. Induction motors may be single-phase or ______
