Abstract

The invention discloses a novel permanent magnet motor capable of dissipating heat which comprises a case, a permanent magnet motor body is arranged on the right side of the interior of the case, thepermanent magnet motor body is fixedly connected with the bottom end of the interior of the case through a mounting frame, a rotating shaft is arranged on the left side of the permanent magnet motor body, and the rotating shaft is fixedly connected with an output shaft of the permanent magnet motor body. According to the novel permanent magnet motor capable of dissipating heat, through cooperationof the case, the permanent magnet motor body, the rotating shaft, the through hole and the heat dissipation mechanism, the rotating shaft can rotate during operation of the permanent magnet motor body, and the conical cylinder can rotate along with the rotating shaft in the process; because the rubber tube on the inner surface of the groove block is pressed against the outer wall of the conical cylinder, the groove block and the fan blade can be rotated together with the conical cylinder during the rotation, gas circulation can be generated on the outer side of the permanent magnet motor bodyin the case in the rotating process of the fan blades, and heat dissipation can be conducted on the permanent magnet motor body in the running period.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to a novel heat-dissipating permanent magnet motor. Background technique [0002] Permanent magnets generally use permanent magnet materials as the motor poles. The so-called permanent magnets refer to materials like magnets that have a magnetic field without an external current. This is relative to the magnetic poles that need to be excited. The one with a magnetic field is not a permanent magnet. The main function is to generate a magnetic field. During the rotation process, the winding cuts the magnetic induction lines generated by it to generate electricity or vice versa. The motors that use permanent magnets synchronously are all synchronous motors. Although the current permanent magnet motor has a certain heat dissipation performance, the heat dissipation power source needs to be realized by an external motor, and it is impossible to dissipate heat for itself d...
