Description
Technical field
The utility model relates to motor technology, relates in particular to a kind of motor.
Background technology
Along with the high speed development of China's economic construction, the increase day by day of global automobile pollution and use amount, energy issue of world is more and more outstanding, and electric automobile engenders and has occupied a very important position at automotive field.Yet because technology is immature, the Performance And Reliability of electric automobile is compared with orthodox car, still has huge spread, and therefore, people keep wait-and-see attitude to electric automobile always.
Motor is a kind of calutron of realizing mechanical energy and electric energy conversion according to the law of electromagnetic induction, mainly comprises stator and rotor two parts usually.For example; Tradition 100kw motor is generally cast-aluminum rotor and forms with the stator that single cover three-phase winding technique forms; Therefore; Not only the motor rotor loss is bigger than normal but also the output torque of motor neither be too high for such motor, and the setting of single cover three phase windings has also influenced the fail safe of electric automobile.
Summary of the invention
The utility model embodiment provides a kind of motor, with the output torque and the power output of increasing motor, and the fail safe that improves electric automobile.
The utility model embodiment adopts following technical scheme:
A kind of motor comprises:
Support, stator, rotor and be sleeved on the rotary encoder on the motor bonnet;
Said stator adopts two covers, three phase windings, and each winding is provided with two coils; The rated current of every cover winding is that 1/2, the two cover three phase windings electrical degree spatially of motor rated current is 30 °.
Can find out through technique scheme; Because motor stator adopts two covers, three phase windings to be intervally arranged; And the rated current of every cover winding is 1/2 of a motor rated current in two covers, three phase windings, and apart electrical degree be common single 1/2 of three phase windings that overlap for 30 ° in the space, therefore; Utilize the utility model embodiment effectively to increase winding distribution ratio, thereby increased the output torque and the power output of motor; If wherein a cover winding breaks down, another set of winding can also guarantee motor running within a certain period of time, thereby has improved the security reliability of electric automobile greatly.
Description of drawings
