Abstract

The invention relates to the technical field of motors, and particularly relates to a high-voltage ultra-high-speed permanent magnet synchronous motor. The high-voltage ultra-high-speed permanent magnet synchronous motor includes a rotor, a rotor composite protective sleeve, a stator core, a stator winding and a machine base, wherein the rotor includes a rotating shaft and multiple pairs of permanent magnets, the multiple pairs of permanent magnets are sequentially arranged along a circumferential direction of the rotating shaft, and any adjacent two permanent magnets are fixedly connected toeach other; the rotor composite protective sleeve includes a carbon fiber layer and a steel wire layer; the stator core includes multiple stator punching sheets, and the multiple stator punching sheets are sequentially stacked to form a whole; the stator winding is configured as a formed winding and is arranged on the side wall of the stator core; and the machine base includes a machine base jacket. According to the scheme of the invention, the technical problems that a motor is poor in heat dissipation effect and large in eddy-current loss, a balancing disc is detached or damaged, and the motor is easy in vibration, high in cost and large in size in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a high-voltage ultra-high-speed permanent magnet synchronous motor. Background technique [0002] With the development of the electric power industry, the application of motors at home and abroad is becoming more and more extensive. Some loads have higher requirements on the speed. However, increasing the speed of the motor will have higher requirements on the performance of the motor. The existing motor Performance is difficult to meet such high requirements. [0003] First of all, compared with other motors, the high-voltage ultra-high-speed permanent magnet synchronous motor produces more heat. At the same time, the stator shielding sleeve on the existing motor is made of stainless steel, resulting in the stator shielding sleeve. The eddy current loss is also large, and the processing equipment is also more expensive; secondly, the higher the motor speed, the more heat will be...
