A Wound Rotor Synchronous Motor is a type of electric motor that operates at synchronous speed, meaning its rotor rotates in sync with the magnetic field produced by the stator. Unlike other motors, it has windings on the rotor, which allows for external control of the rotor current. This feature enables better torque control and starting characteristics, making it suitable for applications requiring high starting torque. These motors are commonly used in heavy industrial applications, such as in mining, pulp and paper mills, and water treatment plants. They are known for their efficiency and ability to maintain constant speed under varying loads, which is essential for many industrial processes.
