Abstract
The utility model relates to a motor of an electric vehicle, which comprises a stator and a rotor, wherein a middle axle is arranged on the stator, a silicon steel sheet is arranged on the rotor, an opening slot is arranged on the silicon steel sheet, a winding is arranged in the opening slot and is connected with an electronic controller, a plurality of permanent magnets are evenly arranged on the inner surface of the silicon steel sheet, and a plurality of permanent magnets are also evenly arranged on the peripheral surface of the stator; the permanent magnets on the inner surface of the silicon steel sheet can be in a strip-shaped structure, and the permanent magnets on the peripheral surface of the stator are in a tile-shaped structure. Because the inner surface of the rotor and the peripheral surface of the stator are both provided with the permanent magnets, magnetic force is generated between the rotor and the stator so that the motor of an electric vehicle of the utility model has the advantages of favorable reduction of resistance moment, effective improvement of starting performance and enhancement of torque and output power.
Description
Technical field
The utility model belongs to electric motors, specifically employed a kind of electric vehicle motor in electric motor car.
Background technology
Existing electric vehicle motor comprises stator and rotor, on stator or the rotor winding is arranged, generate an electromagnetic field after the energising, magnetic field and magnetic field interphase interaction and realize circular motion, this electric vehicle motor needs bigger starting current when starting, consume more electric energy, the startup that electric motor car is frequent under steam, power consumption is bigger.
Summary of the invention
The purpose of this utility model provides a kind of a kind of electric vehicle motor that improves startability.
The purpose of this utility model is achieved in that a kind of electric vehicle motor of the present utility model is made up of stator and rotor, axis is arranged on the stator, silicon steel sheet is arranged on the rotor, open slot is arranged on the silicon steel sheet, winding is arranged in the open slot, winding is connected with electronic controller, is provided with some permanent magnets on the inner surface of silicon steel sheet uniformly, also is provided with some permanent magnets uniformly at the outer peripheral face of stator.
A kind of electric vehicle motor of the present utility model because rotor inner surface and stator outer peripheral face all have permanent magnet, has magnetic force between rotor and stator, helps to reduce the moment of resistance, can effectively improve the startability of electric vehicle motor, improves torque and power output.
Description of drawings
Fig. 1 is the decomposition texture schematic diagram of a kind of electric vehicle motor of the present utility model.
Fig. 2 is the left TV structure schematic diagram of a kind of electric vehicle motor of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, a kind of electric vehicle motor of the present utility model is made up of stator 8 and rotor, axis 7 is arranged on the stator 8, above-mentioned rotor is made of protecgulum 2, shell 3 and bonnet 10, and bearing 1 and bearing 11 are arranged on protecgulum 2 and the bonnet 10, and silicon steel sheet 4 is arranged on the rotor, on the silicon steel sheet 4 open slot is arranged, winding 6 is arranged in the open slot, on the inner surface of silicon steel sheet 4, be provided with 39 strip-shaped permanent-magnet bodies 5 uniformly, also be provided with 10 slices watts of shape permanent magnets 9 uniformly at the outer peripheral face of stator 8.
