Abstract
The utility model discloses a brushless motor of an electric vehicle. A motor stator component is composed of silicon steel stampings of which the centers are provided with web plates and other silicon steel stampings. The peripheral part of the silicon steel stamping is provided with a pyriform winding trough of a motor winding. The motor rotor component is composed of an aluminium wheel hub and magnetic steel which is glued on the hub. The brushless motor of an electric vehicle is characterized in that the silicon steel stampings of which the centers are provided with web plates and other silicon steel stampings are riveted and fixed together, the magnetic steel is a tile magnetic steel which has a certain radian, and each tile magnetic steel is arranged along the circumferential direction and is connected to form a rotundity. The brushless motor of an electric vehicle adopts the structure to make the air gap between the stator and the rotor uniform, the internal resistance is small, and consequently the brushless motor of an electric vehicle improves the electric magnetic property of the motor and the motor efficiency.
Description
Technical field
The utility model relates to a kind of motor, specifically is a kind of electric vehicle brushless motor.
Background technology
Electric motor car at present is because advantage such as emission-free, safe, light is widely used, and as the motor that drives usefulness, usually adopt brushless electric machine, but the rotor of existing brushless electric machine has adopted dull and stereotyped magnet steel at present, stator adopts the press structure of one of band aluminium matter centre frame and silicon steel punching, it is big to exist the motor torque pulsation that rotor air gap inequality causes, internal resistance is big, the not high defective of efficient.
The utility model content
At the defective that above technical scheme exists, the purpose of this utility model is to provide a kind of motor torque fluctuation little, and internal resistance is little, the electric vehicle brushless motor that efficient is high.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of electric vehicle brushless motor, the motor stator parts are made of silicon steel punching and its outer silicon steel punching that the center has disc, wherein silicon steel punching peripheral part is shaped on the pyriform winding slot into motor windings, the magnet steel that motor rotor part is taken turns and is bonded in by aluminium on the aluminium wheel wheel hub constitutes, it is characterized in that: the described silicon steel punching that has disc, be in the same place with its outer silicon steel punching riveted and fixed, described magnet steel is the tile magnet steel with certain radian, and each piece tile magnet steel is connected to circle along circumferentially being provided with.
Described tile magnet steel is 40 and connects into circle, and the mode that 40 blocks of magnet steel are pressed N-S-N-S is uniform, constitutes 20 pairs of magnetic fields.
Described peariform slot is 36, and 72 coils of corresponding motor three phase windings are placed in 36 grooves with putting in order according to the order of connection in twos.
By adopting said structure, the center support employing center of stator component has the silicon steel sheet of disc, can strengthen magnetic loop, and the tile magnet steel that polylith has certain radian is connected to circle, makes that the rotor air gap is even, thus the little electric efficiency that improved of internal resistance.
