To obtain the torque slip characteristics of three phase induction motor.
The load test of a 3 phase induction motor can be performed using electromechanical brakes viz., eddy current brake and powder brake.
EDDY CURRENT BREAK: An eddy current brake, like a conventional friction brake, is responsible for slowing an object, such as a train or a roller coaster.
ELECTROMAGNETIC POWDER BREAK: Electromagnetic power break is based on electromagnetic theory and the use of magnetictorque transmission. Its exciting current and the transmission of torque have a liner relationship between the basic features.
