Problems solved by technology

[0002] The permanent magnet synchronous motor provides excitation with permanent magnets, so that the motor structure is relatively simple. The permanent magnet synchronous motor has a wide range of applications. The permanent magnet synchronous motor in the prior art generally does not have the function of speed regulation. It needs speed regulation and needs to rely on an external transmission. to achieve, which limits the application of motor

Abstract

The invention belongs to the technical field of motors, and particularly discloses a permanent magnet synchronous motor which comprises a shell, wherein the shell is internally provided with a stator, a rotor is rotationally matched in the stator, the rotor is fixedly connected with a rotating shaft, the upper part of the shell is fixedly connected with a mounting box, the end of the rotating shaft is coaxially connected with a conical cover, the conical cover is located in the shell, the inner surface of the conical cover is in friction fit with a conical friction wheel, the taper of the friction wheel is the same as that of the conical cover, the friction wheel is coaxially connected with one end of a second connecting shaft, the second connecting shaft is rotationally installed on a mounting frame, the other end of the second connecting shaft is coaxially connected with a second spline shaft, and the second spline shaft penetrates through a first spline hole which is formed in the middle of the first bevel gear and is in sliding fit with the first bevel gear. The permanent magnet synchronous motor has a stepless speed change function.

Description

technical field [0001] The invention belongs to the field of motors, and specifically discloses a permanent magnet synchronous motor. Background technique [0002] The permanent magnet synchronous motor uses permanent magnets to provide excitation, which makes the motor structure relatively simple. The permanent magnet synchronous motor has a wide range of applications. The permanent magnet synchronous motor in the prior art generally does not have the function of speed regulation, and the speed regulation needs to rely on an external transmission. to achieve, which limits the application of electric motors. SUMMARY OF THE INVENTION [0003] In view of this, the technical problem to be solved by the present invention is to propose a permanent magnet synchronous motor to solve the problems of the prior art. [0004] In order to achieve the above purpose, the present invention provides a permanent magnet synchronous motor, comprising a casing, a stator is arranged in the ca...
