Synchronous Motors are electric AC motors in which the rotor turns at the exact same speed as the rotating magnetic field created by the stator, operating with zero slip under steady load conditions. These motors maintain precise constant rotational speed regardless of load fluctuations, making them ideal for applications requiring exact velocity control or high operational efficiency. Key hardware features typically include permanent magnet rotors or DC-excited rotor field windings, heavy-duty stator assemblies, integrated shaft position sensors, and robust industrial end-bells with heavy-duty bearing housings.
