Description
Technical field
The utility model relates to wheel hub electric motor of electric vehicle.
Background technology
At present; raising along with expanding economy and people's environmental protection consciousness; adopt battery fuel to become the first-selection of most of people's vehicles as the electric motor car power assisting car of power resources, electric bicycle etc.; in the wheel hub electric motor of electric vehicle that most wheel directly drives; this device mainly is made up of motor stator, rotor, axle and parts of bearings; motor is by storage battery power supply, the limited energy the longest mileage that can travel, and this is closely-related with the drive motors performance.The motor wheel hub that can see in the prior art has following shortcoming: under equal wheel hub weight and equal wheel speed, the power of motor is little, and efficient is low, shortcomings such as the complicated and energy consumption height of winding structure.
The utility model content
For overcoming above-mentioned technological deficiency, the purpose of this utility model is to provide a kind of novel wheel hub electric motor of electric vehicle, has the efficient height, the characteristics that winding structure is simple, overload energy is strong.
For achieving the above object, be achieved through the following technical solutions:
Wheel hub electric motor of electric vehicle, include rotor, motor stator, axle and bearing, motor is wheel hub type external rotor and three-phase winding structure, be winding, magnet steel and the wheel hub on motor stator, the stator line embedding groove successively in proper order in the middle of this device, it is characterized in that: the motor wheel hub interior diameter is 205 millimeters, magnet steel is set to 44, and electromagnetic structure is that rotor 22 numbers of pole-pairs cooperate with the coiling of stator 48 groove three-phase and quadrupoles, and magnet steel is circle distribution along the wheel hub inner ring.
Described magnet steel can be set to 52, and electromagnetic structure is that rotor 26 utmost points cooperate with the coiling of stator 48 groove three-phase and quadrupoles accordingly.
Described stator outside diameters is 190 millimeters～205 millimeters, and optimum way is 197.8 millimeters or 198 millimeters.
Adopt the wheel hub electric motor of electric vehicle of said structure, the design of rotor magnetic texure and stator poles logarithm just in time satisfies the demand of load to rotating speed and torque, rational rotating speed and reasonably torque have been reached, thereby do not need various mechanical types speed change, become torquer, avoided unnecessary machine driving and the efficient that causes reduces; Reasonably design makes iron resource, copper resource and the magnetic material resource of motor reach optimized combination.
