Brushless toothless inner brake motor

Abstract

The invention discloses a brushless toothless inner brake motor, which comprises a motor unit and a brake unit, wherein the motor unit comprises a motor shaft, a rotor group and a stator group; the rotor group comprises a hub, magnetic steels, an end cap and a bearing; the brake unit comprises a magnetic brake seat, a moving piece and a friction ring; the hub is a motor shell, and through the endcap, the stator group, the magnetic brake seat, the moving piece and the friction ring are packaged in the hub; the magnetic steels are uniformly attached to the inner circle of the hub; the motor shaft passes through the hub and is fixed in the center position of the hub in a rotary mode through the bearing; and the stator group, the magnetic brake seat, the moving piece and the friction ring allsleeve the motor shaft. The structure is simple and compact, the operation is safe and convenient, brake of the vehicle is completed through a brake unit inside the device, the brake structure of thewhole vehicle is optimized, and the cost is saved.

Description

Technical field [0001] The invention relates to a brushless gearless motor, in particular to a brushless gearless internal brake motor. Background technique [0002] Most of the hub motors of existing electric vehicles use brushless gearless motors or brushless geared motors, and their braking methods are all based on external mechanical structure braking. For example, disc brakes, follow-up brakes, drum brakes and other braking methods can achieve vehicle braking by cooperating with the brake line and using manual brake levers. However, this type of braking method has a complicated structure, and the brake cable routing and manual brake lever occupy the entire vehicle space, which affects the appearance of the entire vehicle; moreover, the exposure of the brake part will cause dust and mud to enter, which will weaken the braking effect and affect the overall performance of the vehicle. ; At the same time, loosening the manual brake lever will cause the wheels to rotate freely, ...

Problems solved by technology

However, the structure of this type of braking method is complicated, and the wiring of the brake wires and the manual brake lever occupy the space of the vehicle, which affects the appearance of the vehicle; moreover, the exposure of the brake part will lead to the entry of dust and sand, which will weaken the braking effect and affect the overall performance of the vehicle. ; At the same time, releasing the manual brake handle will cause the wheels to rotate freely, resulting in the consequences of slipping the car, and there are certain safety hazards
