  • Method for controlling a torque performance of an electrical pitch motor, an electrical pitch-control system and use thereof
    Patent number: 10767627
    Abstract: Method for control of the torque performance of an electric pitch motor (1). A control system (2) comprises a first unit (3) controlling the pitch angle of the rotor blade, a second unit (7) which compares a reference speed Sr with an actual speed Sa of the motor (1) rotational speed. The second unit (7) controls the motor (1) rotational speed, a third unit (10) which regulates the motor (1). The control system (2) comprises a first overload device (13) and a second overload device (14). The second overload device (14) receives an error-speed signal Se, which is the difference between Sr and Sa recorded by the second unit (7). The second overload unit (14) compares See with a maximum allowable speed value, Smax, and the second overload device (14) sends a signal to the motor (1) for the regulation of the torque performance.
