Embodiment Construction

[0010] As shown in the drawings, the DC motor of the electric vehicle of the present invention includes an axle 5, a disc-shaped bracket 4 is fixed in the middle of the wheel-axle 5, and the outer side of the disc-shaped bracket 4 is provided with a wheel rim 1 with a space therebetween. A silicon steel sheet assembly 3 and a coil 7 are installed on the outer circumference of the disc-shaped bracket 4 , and a permanent magnet 8 is fixed on the inner circumference of the wheel rim 1 . Covers 2 are provided on both sides of the wheel rim 1 , and a center hole is machined on the two covers. The axle 5 and the center hole are movably matched through a bearing 6 . Three Hall magnetic induction elements are installed on the silicon steel sheet combination 3 .

[0011] When working, a special controller is used to obtain the N.S pole direction of a group of permanent magnets 8 on the wheel rim through three Hall magnetic induction elements installed on the silicon steel sheet combina...

Abstract

The invention discloses a DC motor of an electric vehicle. The DC motor comprises an axle, a disc-shaped support fixed on the axle, a wheel rim at the periphery of the disc-shaped support, seal covers on both sides of the wheel rim, center holes formed on the seal cover, and a bearing between the axle and the center holes. The DC motor is characterized in that a silicon steel sheet and a coil are arranged on the outer circumference of the disc-shaped support, and a permanent magnet is arranged on the inner circumference of the wheel rim. The DC motor has the advantages of low production cost, no need for frequent maintenance and convenient use, and particularly suits two-wheel electric vehicles.

Description

technical field [0001] The present invention relates to a motor. Specifically, it is a DC motor on an electric vehicle, especially suitable for a two-wheeled electric vehicle. Background technique [0002] At present, the motors used in two-wheeled electric vehicles are all DC brushed motors. A motor with a brush structure has a large amount of enameled wire and a large consumption of raw materials. Therefore, the production cost of this motor is relatively high. And because the carbon brushes and commutators of brushed motors wear quickly, they need to be maintained frequently, which is more troublesome to use. SUMMARY OF THE INVENTION [0003] The problem to be solved by the present invention is to provide a DC motor for an electric vehicle. The direct current motor of the electric vehicle has low production cost, does not require frequent maintenance, and is convenient to use. [0004] In order to solve the above problems, the following technical solutions are adopt...
