Stator of outer rotor type wheel hub motor

Abstract

The invention relates to a stator of an outer rotor type hub motor. The stator comprises a stator core, a stator support, insulating frameworks and stator coils. The stator core comprises a stator core yoke and a plurality of stator core teeth, the stator core yoke is installed on the stator support, the insulating frameworks are fixed on the periphery of the stator core teeth, the stator core teeth are uniformly fixed on the outer ring of the stator core yoke, and the stator coils are wound on the insulating frameworks. Compared with the prior art, the height of the winding end part of the hub motor is reduced, and the structure of the motor is more compact; the outer rotor type hub motor has the advantages of being lighter in weight, smaller in size and convenient to produce in batches,more convenience is provided for index achievement and batch production of the hub motor, and the stator of the outer rotor type hub motor is quite suitable for being used in the outer rotor type hubmotor for the distributed four-wheel drive electric vehicle with strict requirements for the size and the weight of the motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator of an outer rotor type hub motor. Background technique [0002] With the increasing air pollution and the continuous reduction of oil resources, in order to solve the problems caused by traditional fuel vehicles, people are investing more and more in the development of electric vehicles, and electric vehicles will replace traditional fuel vehicles. Compared with traditional fuel vehicles, electric vehicles have fewer harmful substances, even zero emissions, and electric vehicles have lower noise. As a new energy drive motor, the outer rotor hub motor has many advantages. For example, it can be directly installed inside the rim of the wheel to directly drive the car, saving the space occupied by the car power system, and reducing the weight and structural complexity of the vehicle. This driving method can shorten the transmission path of power and cancel the entire power ...

AI Technical Summary

Problems solved by technology

[0003] The wheel hub motor is installed in the rim of the car, and the installation space of the motor is very limited. In the existing common outer rotor hub motor, the insulation of the stator core slot is in the form of insulating paper. Put the insulating paper into the bottom of the slot, and put the coil into the slot. Finally, the coil is fixed with slot wedges. In this way, the end of the winding is higher and the volume of the motor is larger, which is not conducive to the installation and layout of the whole vehicle.
