Abstract

The invention discloses a water-cooled double-speed motor and a control system thereof, and relates to the technical field of water-cooled motors. The water-cooled double-speed motor includes a controller, the controller comprises a starting device used for starting the motor, an executing device used for controlling the rotating speed of the motor and a detecting device used for detecting the motor in real time, the output end of the controller is electrically connected with the input end of the starting device through a wiring harness, and the output end of the starting device is electrically connected with the input end of the executing device through a wiring harness. By arranging the rotating speed sensor, when the rotating speed of the low-speed motor reaches the rated value of the rotating speed sensor, the high-speed motor starter enables the high-speed motor to start rotating, when the rotating speed of the low-speed motor cannot reach the rated value of the rotating speed sensor, the high-speed motor starter enables the high-speed motor to stop rotating, the rotating speed of the motor can be controlled through the double-speed motor according to actual needs, and the application range is enlarged.

Description

technical field [0001] The invention relates to the technical field of water-cooled motors, in particular to a water-cooled two-speed motor and its control system. Background technique [0002] The water-cooled motor has a brushless structure, excellent load characteristics, good low-speed performance, large starting torque, small starting current, adapts to the needs of frequent starting of electric vehicles, and saves electric energy. And multi-speed motors for furnaces and other series of motors are developed and designed according to the needs of metallurgical continuous casting machines and billet discharge site conditions. It is suitable for high-temperature environments and frequency conversion speed regulation systems. The existing water-cooled motors are often only equipped with a single motor when used, and the scope of use is limited. Therefore, we improve this and propose a water-cooled two-speed motor and its control system. Contents of the invention [0003...
