Abstract
The utility model relates to a motor, in particular to a novel disk type outer rotor DC brushless motor for an electric vehicle, which comprises a flange base, a motor stator, a disk type outer rotor and a mid shaft; wherein the motor stator is fixed on the flange base through a screw, the disk type outer rotor is connected with the mid shaft through a mid shaft locknut and a positioning pin, the disk type outer rotor is buckled on the exterior of the motor stator, the mid shaft passes through the central bearings of the motor stator and the flange base and stretches out of the center of the flange base to form a novel disk type outer rotor DC brushless motor which overcomes the friction and the electric energy loss between a DC brushed motor carbon brush and a commutator and overcomes the defects of that an inner rotor DC brushless motor has the small torque and the poor radiating effect, and an outer rotor wheel hub DC brushless motor has the large torque and the good radiating effect but no mid shaft output; therefore, the utility model has the advantages of the simple manufacturing process, the high efficiency, the large torque, the easy radiation, the mid shaft output and the convenient installation and use.
Description
Technical field
The utility model relates to a kind of direct current machine, mainly refers to a kind of novel disc type external rotor dc brushless motor that electric motor car is used above.
Background technology
At present, along with the continuous growth of oil price and a large amount of dischargings of vehicle exhaust, a kind of novel walking-replacing tool battery-operated motor cycle, electric automobile will move towards market, the not only environmental protection but also energy-conservation of this car, create considerable economic can for society, still, battery-operated motor cycle, mostly adopt the internal rotor dc brushless motor above the electric automobile, external rotor wheel hub dc brushless motor, brush direct current motor.Though this three classes motor respectively has advantage, but relative battery-operated motor cycle and electric automobile, but all exist corresponding not enough, be unfavorable for the speed-raising of electric motor car and the repacking of existing vehicle, if any the brush motor speed when high carbon brush easy to wear, ablate, reduce electric efficiency, when the internal rotor direct current brushless motor speed is high, moment of torsion is little, though external rotor wheel hub dc brushless motor moment of torsion is big, does not have mid-output, and can not too highly raise speed, therefore, brush direct current motor, inner-rotor brushless direct current machine, external rotor wheel hub dc brushless motor all are not suitable for assembling the high speed electric car.
The utility model content
The purpose of this utility model provides a kind of novel disc type external rotor dc brushless motor, the moment of torsion that has at the original external rotor wheel hub dc brushless motor of reservation is big, be easy to heat radiation, under the high preceding topic of efficient, make this external rotor wheel hub dc brushless motor have mid-axle output, the external rotor wheel hub becomes the web-type flywheel structure, thereby has increased the moment of torsion of external rotor dc brushless motor, during the motor high-speed cruising, moment of torsion is bigger.
For achieving the above object, a kind of novel disc type external rotor dc brushless motor of the present utility model is made up of ring flange base, motor stator, disc type external rotor, mid-axle, motor stator central authorities bearing, ring flange base central authorities bearing, stator coil, magnetic cylinder, screw, screw hole, wire hole, axis locknut, alignment pin; Motor stator is fixed on the ring flange base by screw, motor stator central authorities bearing is embedded in the central authorities of motor stator, ring flange central authorities bearing is embedded in the central authorities of ring flange base, the disc type external rotor covers on the motor stator and by the axis locknut and links to each other with mid-axle with alignment pin, mid-axle passes motor stator central authorities' bearing and ring flange base central authorities bearing, central authorities in ring flange one side stretch out, and form a kind of tray type structure.
Owing to adopted such scheme: the disc type external rotor can do the thick intermediate thin in the big edge of diameter, have big rotator inertia and running speed, changed the structure of existing dc brushless motor, has mid-axle output, thereby the carbon brush that has solved brush motor weares and teares, moment of torsion was little when the internal rotor direct current brushless motor speed was high, the little problem of moment of torsion when external rotor wheel hub dc brushless motor does not have mid-axle output to run up, make disc type external rotor dc brushless motor have rotating speed height, big, the mid-axle output of moment of torsion, be fit to assembling high speed electric car.
