Answer / jaggannath swami

b for wht u did not clearifed In my opinion BKW means breaking kilowatt. motor run when we stop the motor its produce some heat to use of stopping the motor than this typwe of regenerating the back energy to oppose the motor motion & its closed to stop

when an induction motor runs on load.at that time if we reduce the supply voltage the current increases.But when it runs without load,if we reduce the supply voltage the current also reduced.why?.i checked it practically also.
