Answer / shahbaz shaikh

as the load increases means motor draw more current from supply to satisfy the load torque up to the saturation region speed is inversely proportional to the load current hence as load current increases speed is decreases
in case of synchronous motor as load increases there is no effect on the speed but there is change on the operating power factor of load and load angle is change with load but speed remains constant
