A super high speed small permanent magnet motor

Abstract

The invention discloses an ultrahigh-speed small permanent magnet motor which includes a permanent magnet motor. A motor shaft is installed on the right side of the permanent magnet motor. A shell isinstalled on the outer wall of the permanent magnet motor. A front side plate is connected with a rear side plate through a water pipe. A water inlet pipe is installed on the top end of the rear sideplate. A top cover is arranged on the top end of the water inlet pipe. A bent rod is arranged at the bottom end of the top cover. A connecting plate is installed on the top end of the bent rod. According to the ultrahigh-speed small permanent magnet motor, cooling liquid flows into the water inlet pipe of the front side plate for circulation through the water pipe, cooling liquid can be poured ineasily, and the heat generated by the permanent magnet motor during high-speed rotation and the influence of heat on the service life are reduced. The top cover is closed, and the turntable is rotated, so that the screw rod on the top cover and the screw cylinder on the turntable are connected, the top cover is fixed to the water inlet pipe, the water inlet pipe can be better protected and closed,and the problem that the permanent magnet motor is damaged and certain loss is caused due to the leakage of cooling liquid during work of the permanent magnet motor is avoided.

[0002] The permanent magnet motor is a rectangular pulse wave, current sine wave current, hybrid permanent magnet motor form, the form of the permanent magnet motor is: 1 rectangular pulse wave current, permanent magnet brushless DC motor PMBDC has a rectangular pulse wave current, 2 Sine wave current, permanent magnet reluctance synchronous motor PSM has a sine wave current, 3 hybrid permanent magnet motors, such as the patent application number 201320486569.4, including a rotor, a stator, and windings, the rotor is placed inside the stator, and The rotor includes a hollow shaft and a permanent magnet. This patent cannot effectively dissipate heat from the permanent magnet motor, and cannot protect and close the water inlet pipe, and the tightness of the water inlet pipe is not enough, which causes the permanent magnet motor to cool when it is working. The leakage of liquid will affect the use effect of permanent magnet motor and reduce the service life of permanent magnet motor
