Torque motors


Construction: -
The winding of the motors are as same as the winding of three phase Sq. cage motor but there is a change the rotor. Instead of aluminum rotor, rotor is made out of M.S. rods and short circuiting ring is removed

Operation: -
The motor rpm is controlled either by providing three phase variac in series with stator winding or by providing only single phase variac in series with any one phase of supply. As the stator voltage is increase or decrease, the emf in the stator winding becomes stronger or weaker, this results in increase or decrease of motor rpm with constant torque.



Applications :-

Brake Motors are used for numerous applications. A few of them are listed below :

Textile Industries Plastic Industries Machine Tools
Steel Rolling Ind. Wire Winding Machine
