Abstract
The utility model discloses a monopole multichip homopolar permanent magnetism motor, comprising a rotor and a plurality of magnetic steels. The magnetic steels are fixedly arranged on the inner side surface of the rotor, the N-poles and S-poles of the magnetic steels are arranged in turn and alternately, and a mutually alternatively arranged magnetic pole (N pole or S pole) is formed by arranging a plurality of magnetic steels. By using the single magnetic pole multichip magnetic steel permanent magnetism motor of the utility model, the situations can be guaranteed that the thicknesses of the magnetic steels can be reduced on the condition of not changing the cross-sectional area of the single magnetic steel, and the rated power of the motor is not affected.
Description
Technical field
The utility model relates to a kind of single magnetic pole multi-disc set magnet permanent motor.
Background technology
The magnetic pole of magneto is that the S utmost point, the N utmost point are alternately arranged.Magneto in the market is utmost point a slice magnet steel, because of the electric machine structure factor, makes magnet steel not only long but also narrow.For the demagnetization that guarantees magnet steel within the specific limits, must guarantee certain thickness, make draw ratio reach certain ratio.
According to magneto magnetic circuit principle, the thickness of magnet steel within the specific limits.Thick behind certain value when magnet steel, unnecessary thickness does not just have too many contribution to motor properties.But behind the thickness low LCL, it is big that the draw ratio of magnet steel becomes, and the temperature resistant grade of magnet steel is not enough again, reduces the rated power of motor.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of single magnetic pole multi-disc set magnet permanent motor, and this motor can guarantee to reduce under the constant situation of the cross-sectional area of monolithic magnet steel the thickness of magnet steel, and does not influence the rated power of motor.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of single magnetic pole multi-disc set magnet permanent motor; Comprise rotor and some blocks of magnet steel; Said magnet steel is fixedly arranged on the said rotor medial surface; And the N utmost point of said magnet steel and the S utmost point are alternately arranged successively, and a said magnetic pole (the N utmost point or the S utmost point) of alternately arranging is each other arranged by some blocks of magnet steel and formed.Like this, can under the constant situation of the cross-sectional area that guarantees the monolithic magnet steel, reduce the thickness of magnet steel, total draw ratio is constant, and the temperature resistant capability of magnet steel increases, and the rated power of motor can not reduce, thereby reduces the cost of motor, rationally utilizes magnetic aptitude source.
As the further improvement of the utility model, a said magnetic pole of alternately arranging each other is arranged in parallel along the rotor axis direction by two blocks of identical magnet steel and forms.
As the further improvement of the utility model, a said magnetic pole of alternately arranging is each other arranged side by side along the rotor axis direction by two blocks of identical magnet steel and is formed.
As the further improvement of the utility model, a said magnetic pole of alternately arranging is each other arranged side by side along the rotor axis direction by three blocks of identical magnet steel and is formed.
As the further improvement of the utility model, a said magnetic pole of alternately arranging is each other arranged by four blocks of identical magnet steel and is formed.
The beneficial effect of the utility model is: this motor can reduce the thickness of magnet steel under the constant situation of the cross-sectional area that guarantees the monolithic magnet steel; Total draw ratio is constant, and the temperature resistant capability of magnet steel increases, and the rated power of motor does not reduce; Thereby reduce the cost of motor, rationally utilize magnetic aptitude source.
