Why slip ring induction motor is not started with its slip ring short circuited?
The rotor of the slip ring induction motor is connected to the external resistances. When the motor is started, the total external resistance gets added … Read more
About 98 % of the motors used in the world is induction motor. The induction motor is simple in construction. It is robust,rugged and reliable motor. All the posts written about induction motor is useful for engineering students and the professional engineers working in the field. I tried to cover every practical aspects in the posts. Happy Readings !!!
