Abstract

The invention relates to the technical field of high-voltage permanent magnet synchronous motors, and discloses a rotor permanent magnet series distribution-linked high-voltage permanent magnet synchronous motor, which comprises a motor shell, a stopper is fixedly connected with the motor shell, a first fixing seat is fixedly connected with stopper, a second fixing seat is fixedly arranged on theinner wall on the right side of the motor shell. The rotor permanent magnet series distribution-linked high-voltage permanent magnet synchronous motor can make the waveform of the counter electromotive force achieve the best effect as long as the design of each segment length is appropriate, the useless harmonic generated by the stator is minimized, the harmonic loss is minimized, the motor achieves high efficiency, the manufacturability is good, the rotor punching die is most simple, and each magnetic steel is easy to install due to small volume, and the design level and the process level ofthe high-voltage permanent magnet motor become reliable and efficient, so that the design of this type of motor becomes feasible, and meanwhile, the motor can be applied to various complex occasions.

Description

technical field [0001] The invention relates to the technical field of high-voltage permanent magnet synchronous motors, in particular to a high-voltage permanent magnet synchronous motor in which rotor permanent magnets are connected in series and distributed. Background technique [0002] For high-voltage permanent magnet motors, due to the large volume of the motor, the motor is divided into fewer poles. For 4 poles or 6 poles, the volume occupied by each pole of the motor rotor is large. When the motor uses permanent magnets, each magnetic pole bears the magnetic energy product If it is too large, from the analysis of electromagnetic theory, the possibility of loss of magnetism is greater, and a large amount of magnet steel is consumed at the same time. There is no possibility of application. [0003] The following invention is based on the distribution of permanent magnets in the rotor of a high-voltage permanent magnet motor. Due to the large power and torque of the h...
