Embodiment Construction

[0014] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0015] according to figure 1 As shown, the present invention can realize that the stator armature 2 of the hub motor is installed on the armature support base 1 with the cooling channel 4 fixed to the wheel bearing seat in practical application. exist figure 1 The armature support plate 3 shown in the figure also plays the role of structural support for the stator armature 2 after assembly, and the formation of double supports improves the structural strength. Since the technical invention adopts the integrated design of the cooling channel 4 and the supporting parts of the motor stator armature 2, it not only meets the cooling requirement of the armature 2, but al...

Abstract

The invention discloses a motor stator structure of a hub motor. The motor stator structure is characterized in that several cavities are formed in the inner side of an armature in one circle; a segment of each cavity is used for installing a driving controller of the hub motor, and the driving controller controls operation of the hub motor and monitors and manages the operation state of the hub motor in real time; in the low-speed and large-torque operation state, the heat of the hub motor is dissipated through a cooling flow channel specially designed, and therefore the safe running requirement of an electric car can be met; due to the fact that the work environment of the hub motor is severe and the hub motor needs firm supporting, a bilateral supporting structure is adopted to meet the rigidity requirement of the hub motor; in the design of an inner-side supporting plate, a detachable structure is designed from the aspect of the assembly technique smoothness and maintenance, components having faults during operation can be replaced, and therefore the use cost is lowered.

Description

technical field [0001] The patent of the present invention is a stator armature structure design for a hub motor of an electric vehicle. [0002] Background technique [0003] At present, in the application fields of new energy vehicles emerging in the world, whether it is a gasoline-electric hybrid vehicle or a pure electric vehicle, two or more wheel hub drive motors with light weight and high power are required. The same is true in our country. The country has issued many incentive policies for new energy vehicles, and the new energy vehicle market is already gaining momentum. [0004] Although there are many new technology products in the design of in-wheel motors, such as magnetically controlled switch motors and axial motor technology products, they have all begun to enter people's field of vision and market. At present, these DC motors for vehicles all have one thing in common, that is, they are larger in size and heavier in weight. [0005] According to the develo...
