________ are employed for the operation of Jaw Crushers.

Right Answer is:

Belted slip ring induction motor

SOLUTION

Belted slip ring induction motors are employed for the operation of Jaw Crushers.

  • Starting torque is directly proportional to the rotor resistance of an induction motor.
  • In the SLIP RING induction motor the ends of the rotor windings are externally connected by a variable rheostat (resistance is varied in order to give it proper starting and running current).
  • So more the resistance, more the torque. When we add resistance to the rotor the torque is high, the slip is high and the current is reduced.
  • Therefore slip ring induction motor is used for providing high starting torque.
  • Important Reluctance Motor MCQ
  • Belted slip ring induction motor is almost invariably used as, very often, the motor has to start against the heavy load or a stuck crusher.
