Embodiment 1

[0039] See figure 1 , figure 2 , image 3 , in this embodiment, the tangential permanent magnet and the radial permanent magnet adopt the hard magnetic NdFeB material, and the other parts of the engine require the use of diamagnetic materials such as copper alloys. In order to meet the needs of dynamic balance, there are 16 pieces of radial permanent magnets. For the convenience of processing, the magnetic pole α is a 90° sharp angle, and 15 pieces of rectangular tangential permanent magnets are used. The positional relationship between the tangential permanent magnets and the radial permanent magnets is: When the lower end of the tangential permanent magnet just completely enters the radial permanent magnet during rotation, the upper end of the tangential permanent magnet just passes over the sharp corner of the magnetic pole of the peripheral permanent magnet having the same name as the magnetic pole.

[0040]When the end of the magnet points to the middle line of the two...

Embodiment 2

[0043] The positions between stator and rotor are interchangeable (see Figure 4 ).

Embodiment 3

[0045] See Figure 5 , in this embodiment, the tangential permanent magnets are installed on the stator, and the radial permanent magnets are installed on the rotor. In order to meet the needs of dynamic balance, there are 9 pieces of radial permanent magnets, and the sharp angle end α of the magnetic pole is 100° sharp angle, and 8 pieces of rectangular tangential permanent magnets are used. The positional relationship between the tangential permanent magnets and the radial permanent magnets is: When the lower end of the permanent magnet has just completely entered the radial permanent magnet during rotation, the upper end of the tangential permanent magnet has just crossed over the sharp corner of the magnetic pole of the peripheral permanent magnet with the magnetic pole of the same name.

[0046] In an embodiment, the ratio of the number of tangential permanent magnets to radial permanent magnets can also be:

[0047] 24:25, 31:32, 46; 48, 62:64, etc.

Abstract

A permanent magnet motor comprises a stator and a rotor. Two groups of permanent magnets are arranged on the stator and the rotor respectively, and each of the groups of permanent magnets is distributed uniformly at equal intervals on the circumference. Magnetic poles of one group of permanent magnets are arranged tangentially, same poles face towards same tangential directions, magnetic poles of the other group of permanent magnets are arranged radially, and same poles are distributed uniformly circumferentially. The permanent magnet motor has the advantages of being applicable to motor vehicle power generators and power generation equipment and adjustable in power output magnitude.

Description

technical field [0001] The invention relates to a power output device, in particular to a device for converting the magnetic energy of a permanent magnet into mechanical energy. Background technique [0002] With the development of science and technology and the continuous improvement of people's understanding, the characteristics of using permanent magnets to do work without consuming their own energy have begun to be used by people, such as magnetic separators, magnetic levitation trains, magnetic levitation bearings, magnetic couplings, etc. According to the characteristic that the permanent magnet does not consume its own energy when doing work externally, in a sense, the magnetic energy of the permanent magnet does not obey the energy conservation. Permanent magnets have magnetic energy, using the magnetic energy of permanent magnets to save energy, reduce costs and simplify equipment structure, has been applied in the field of automobiles and motors. For exampl...
