Description
Technical field
The utility model is related to field of motor manufacturing, more particularly to a kind of permanent magnetic brushless.
Background technology
The electric vehicle motor of early application is most of all to use permanent magnetic brushless, and concentratred winding is carried out using fractional-slot,
Fractional-slot concentratred winding is more mainly for solving motor number of pole-pairs, the contradiction between number of slots is few, while torque pulsation is reduced,
Make electric car traveling as far as possible steady.But fractional-slot concentratred winding vortex is damaged magnet and damaged than larger, is not suitable for weak magnetic control, fractional-slot
Though concentratred winding can be reduced " slot effect ", to sacrifice the part efficiency of motor as cost, while Distributed Winding permanent magnetism
Brushless electric machine, stator end copper cash span is larger, and coil DC impedance is big, and line loss increase, copper material wastes serious, now country number
Call " energy-saving and emission-reduction, energy-efficient " together, so efficiency high must be developed, the big permanent magnetic brushless of moment of torsion.
The content of the invention
Utility model purpose：In order to overcome the deficiencies in the prior art, the utility model provides a kind of efficiency high,
Moment of torsion is big, and electric current is low, and temperature rise is low, and noise is low, and stability is high, and manufacturing process is simple, the low permanent magnetic brushless of cost.
Technical scheme：To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of permanent magnetic brushless, including motor housing, rotor and stator, described rotor be superimposed by rotor punching and
Into, described stator is formed by stacking by stator punching, and described rotor punching is disposed with axis hole from inside to outside, heat emission hole,
Rotor mounting hole and lobe 8, the spacing between lobe are 21mm, and the center of lobe is also provided with circular groove, described stator punching
Circle is disposed with rotor hole, teeth groove, winding slot and stator mounting hole from inside to outside, and described space width is 1.67mm.
Further, it is additionally provided with inwardly protruded spacer block in described axis hole.
Further, described heat emission hole is sector structure, and heat emission hole is rounded evenly distributed around axis hole, and quantity is 4
It is individual.
Further, described rotor mounting hole is circle, is staggered with heat emission hole, quantity is 4.
Further, described winding slot is trapezoidal shape, and shorter one side sets opening, and winding slot is in around rotor hole
Circular arrangement, quantity is 12.
Further, described stator mounting hole is circle, rounded to be arranged in stator punching outer ring, and quantity is 6.
Beneficial effect：The utility model provides a kind of permanent magnetic brushless, optimizes the armature diameter and motor of motor
Groove profile, using Stator notching and optimization rotor pole arc coefficient and width of rebate, stator cramp groove horizontal is changed to by original
Vertical, then reduce the influence of multipair motor magnetic circuit to the full extent, changing stator slot shoulder shape makes motor stator punching mould
It is more robust, it is designed go out motor is more efficient compared to original motor, lower temperature rise, noise and torque ripple it is minimum.
