Double-speed motor control device and method

The invention, which belongs to the technical field of nuclear power maintenance, particularly relates to a double-speed motor control device and method. According to one embodiment, the invention provides a double-speed motor control device. A control logic in the controller is used for replacing the traditional relay contact type control system and long-term electrified work of a relay is not required, so that the service life of components is prolonged and the motor controllable device has high reliability. Moreover, the controller is small in size and good in anti-interference capability and the stability of the control system is improved. 本发明属于核电维修技术领域，具体涉及一种双速电动机控制装置及方法。根据本公开实施例的一方面，提供一种双速电动机控制装置，本公开实施例使用控制器内部的控制逻辑取代传统继电器接触式的控制系统，无需继电器长期带电工作，延长元器件的使用寿命，使得电动机可控制装置具有较好的可靠性，且控制器体积小、抗干扰能力好，提升控制系统的稳定性。
