Abstract
The utility model discloses a permanent magnet motor suitable for overall magnetization. The permanent magnet motor comprises a rotor, wherein the rotor comprises eight magnetic poles, a permanent magnet material is stuck to each magnetic pole, the surface of each magnetic pole is divided into at least two groups of planes with the same length, and the contact surface of the permanent magnet material and each magnetic pole is correspondingly divided into at least two groups of planes with the same length. Due to the adoption of the structure, in the overall magnetization process, the counter current generated by a counter magnetic field can be blocked when circulating on the surface of the rotor, and the counter magnetic field can be choked when the counter current is blocked, so that the smooth overall magnetization can be ensured.
Description
Technical field
The utility model relates to a kind of magneto, refers more particularly to a kind of magneto that integral body magnetizes that is applicable to.
Background technology
At present, the technology that magneto integral body magnetizes is developed, because technology maturity is inadequate, a lot of problems have been run into, wherein be the most significantly, the counter magnetic field that magneto produces in the process that integral body magnetizes has affected the efficient that magnetizes greatly, causes the utilance of permanent magnetic material lower, its reason is that the magnetic pole of the rotor of state's permanent magnet motor mostly is curved surfaces, and this structure is not suitable for integral body and magnetizes.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly can be applicable to the magneto that integral body magnetizes.
In order to solve the problems of the technologies described above, the utility model is a kind of magneto that integral body magnetizes that is applicable to, comprise rotor, rotor comprises 8 magnetic poles, post permanent magnetic material on each magnetic pole, magnetic pole surfaces is divided into the isometric plane of at least two groups, and the surface that permanent magnetic material contacts with magnetic pole is divided into the isometric plane of at least two groups accordingly.
Adopt said structure, its beneficial effect is: each magnetic pole surfaces of rotor is divided into the isometric plane of at least two groups, this structure is commonly called as " mosaic " structure, so in the process that integral body magnetizes, the counter current that counter magnetic field produces can be blocked when rotor surface circulates, when counter current stream was blocked, counter magnetic field namely can be controlled, thereby had guaranteed whole carrying out smoothly of magnetizing.
Description of drawings
Fig. 1 is the structural representation that the utility model is applicable to the magneto that integral body magnetizes.
Fig. 2 is the structural representation of a magnetic pole of the utility model permanent magnet machine rotor.
Among the figure: 1-rotor, 2-magnetic pole, 3-permanent magnetic material, the isometric plane of 4-.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, a kind ofly be applicable to the magneto that integral body magnetizes and comprise rotor 1, rotor 1 comprises 8 magnetic poles 2, post permanent magnetic material 3 on each magnetic pole 2, magnetic pole 2 surfaces are divided into the isometric plane 4 of at least two groups, and the surface that permanent magnetic material 3 contacts with magnetic pole 2 is divided into the isometric plane 4 of at least two groups accordingly.
When using magnet charger that magneto is magnetized, the Permanent Magnet and Electric chance produces resists a counter magnetic field that magnetizes magnetic field and produce, counter magnetic field forms counter current, because the surface design of each magnetic pole 2 of the present utility model is the isometric plane 4 of at least two groups, be commonly called as " mosaic " structure, the Nodes of counter current between isometric plane 4 can be blocked, thereby can not form circulation, counter magnetic field namely can be controlled, and has guaranteed carrying out smoothly of the whole process that magnetizes.
Should be appreciated that the utility model is not limited to above-mentioned execution mode, allly become " mosaic " structure to be beneficial to magneto is carried out the mode that integral body magnetizes magnetic pole 2 surface design, all fall into protection range of the present utility model.
