Nettet29. des. 2024 · Synchronous Motor on Load : When a synchronous motor is loaded, though the speed remains constant but the load angle α increases i.e., the angle by which the rotor pole axis lies behind the stator pole axis increases. As load angle α increases, the resultant voltage E r increases, and the current drawn by the motor also increases.
