Abstract

The invention discloses a surface-mounted permanent magnet motor structure, and belongs to the technical field of motor design. The surface-mounted magnetic steel design provided by the invention belongs to a partially embedded magnetic steel arrangement mode and has a great difference from a general magnetic steel arrangement mode in design emphasis. The structure comprises a stator iron core and a stator winding connected with the stator iron core. A rotor iron core is arranged between the stator iron core and a shaft. The magnetic steel and a welfless band are arranged between the rotor iron core and the stator iron core. Rotor end plates are arranged at two transverse sides of the rotor iron core. Self-cooling centrifugal fan blades are arranged on the rotor end plates. Two sides of the rotor iron core axially close to the shaft are equipped with rotor tensional fastening elements. The structure is simple in structure and low in cost and is suitable for mass production. According to the structure, the motor is ensured to have good speed regulation characteristic and operation reliability.

Description

technical field [0001] The invention belongs to the technical field of motor design. Among them, the design of the surface-mounted magnets of the present invention belongs to the layout of partially embedded magnets, which is also very different from the usual layout of magnets in terms of design focus. Background technique [0002] my country is a country rich in permanent magnet materials, especially rare earth permanent magnet material NdFeB resources are very rich in my country, and the reserves of rare earth ore are about 4 times the sum of other countries in the world. The scientific research level of rare earth permanent magnet materials and rare earth permanent magnet motors has reached the international advanced level. Therefore, for our country, the permanent magnet synchronous motor has a good application prospect. The permanent magnet synchronous motor has simple structure, small size, light weight, low loss, high power density, and high efficiency. Compared wi...
