Abstract
The utility model provides a kind of magneto, comprises stator and rotor, it is characterized in that described rotor axially on be provided with several magnet steel grooves, it is symmetrical on rotor that 2 one group of described magnet steel groove is V-shape, in described magnet steel groove, is provided with magnet steel.The utility model is compared with traditional motor, has greatly improved the waveform of air gap flux density, has reduced harmonic wave, has reduced torque pulsation, and has alleviated weight, has increased radiating effect, reduces power consumption.
Description
Technical field
The utility model belongs to motor, specifically a kind of magneto.
Background technology
Magneto has torque density, the advantage that power density is larger, and this makes magneto more and more become the selection of electric drive system for electric vehicles.Current magneto, the outer surface of rotor and the air gap flux density between stator approach flat-topped wave, and the harmonic wave comprising is more, can form the adverse effects such as back-emf, torque pulsation, if adopt the magnet steel of other shape, can increase cost and difficulty of processing.In addition, common magneto, weight is heavier, has increased vehicle weight and electric energy loss.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of magneto.
A magneto, comprises stator and rotor, it is characterized in that described rotor axially on be provided with several magnet steel grooves, it is symmetrical on rotor that 2 one group of described magnet steel groove is V-shape, in described magnet steel groove, is provided with magnet steel.
Described a kind of magneto, it is characterized in that 2 one group of described magnet steel groove is V-shape, and the opening of V word is towards the center of circle of rotor.
Described a kind of magneto, is characterized in that described magnet steel groove has 4 groups, symmetrical on rotor.
Described a kind of magneto, is characterized in that described magnet steel groove and magnet steel are rectangular.
Described a kind of magneto, it is characterized in that described rotor axially on be provided with several through holes.
Described a kind of magneto, is characterized in that described through hole is arranged on the position between two adjacent groups magnet steel groove.
Described a kind of magneto, is characterized in that described through hole is fan-shaped.
Described a kind of magneto, the length that it is characterized in that described rotor is 70%-90% of stator length.
Described a kind of magneto, the length that it is characterized in that described rotor is 80% of stator length.
Magneto of the present utility model, compares with traditional motor, has greatly improved the waveform of air gap flux density, has reduced harmonic wave, has reduced torque pulsation, and has alleviated weight, has increased radiating effect, reduces power consumption.
Accompanying drawing explanation
Fig. 1 is rotor profiles figure of the present utility model;
Fig. 2 is stator of the present utility model and rotor vertical view;
In figure, 1-rotor; 2-magnet steel groove; 3-magnet steel; 4-through hole; 5-stator.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As depicted in figs. 1 and 2, a kind of magneto of the present utility model, comprise stator and rotor, described rotor axially on be provided with 8 rectangular magnet steel grooves, it is symmetrical on rotor that 2 one group of 8 magnet steel groove is V-shape, and the opening of V word, towards the center of circle of rotor, is provided with rectangular magnet steel in described magnet steel groove.Such structural design has been improved the waveform of air gap flux density greatly, has reduced harmonic wave, has reduced torque pulsation.Rotor axially on be provided with 4 fan-shaped pylones, through hole is arranged on the position between two adjacent groups magnet steel groove.The length of rotor is 80% of stator length.The design of fan-shaped pylone and rotor length, the weight of the motor of low minimizing to greatest extent not only, and guaranteed mechanical strength and the work of rotor, and improved to greatest extent the heat dispersion of motor.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within being all included in protection range of the present utility model.
