in general motors are the machine which convert electrical energy to mechanical energy so if we want to convert motor to generator then we have to couple the motor shaft with some external turbine or d.c motor or pony motor so bye providing the high speed more then its synchronous speed we can make the motor as generator which have negative slip.
