Embodiment Construction

[0033] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] figure 1 It is a longitudinal sectional view of a hub type axial excitation permanent magnet motor of the present invention.

[0035] It consists of bearing (1), shaft (2), hub (3), stator core (4), permanent magnet (6), armature winding (7), stator pole (8), rotor pole (9) and hub cover ( 10) Composition;

[0036] The disc-shaped stator core (4) is fixed in the middle of the shaft (2), the inner rings of the two bearings (1) are respectively fixed at both ends of the shaft (2), and the outer rings of the two bearings (1) are respectively fixed In the central hole of the hub (3) and the hub cover (10), under the action of the bearing (1), the hub (3) and the hub cover (10) can rotate around the axis (2), thereby driving the wheel to rotate;

[0037] A permanent magnet (6) and a stator pole (8) are sequentially fixed on the opposite end surface of the stator...

Abstract

The invention provides a hub-type axial excitation permanent magnetic motor. The hub-type axial excitation permanent magnetic motor is formed by bearings, an axle, a hub, a stator core, a permanent magnet, armature windings, stator poles, a rotor pole and a hub cover, wherein the hub and the hub cover can rotate around the axle so as to drive a wheel to rotate; the disc type stator core is fixed at the middle part of the axle; the permanent magnet and the stator poles are successively fixed on the end surface, relative to the hub cover, of the stator core; a corresponding armature winding winds around each stator pole; and the rotor pole which is convex in the axial direction is fixed on the inner wall, facing toward the stator pole, of the hub cover. For the hub-type axial excitation permanent magnetic motor, as both the permanent magnet and the armature windings are arranged on the stator, the rotor structure is simple and works reliably; as the contact surface between the stator and the rotor is large, the conductable maximum magnetic flux is large and the motor power is high; and the integrated design of the drive motor and the hub is realized, so that a decelerator is saved and the transmission efficiency is high.

Description

technical field [0001] The invention relates to a hub-type axial excitation permanent magnet motor, which belongs to the technical field of automobile electric appliances. Background technique [0002] The hub motor is one of the core components of the future electric vehicle. Its biggest feature is that the drive, transmission and braking devices are integrated into the hub, omitting the clutch, transmission, drive shaft, differential, transfer case and other transmissions. part. As consumers pay more and more attention to new energy vehicles, in-wheel motor technology will also come into people's field of vision, leading to an explosive growth in the demand for in-wheel motors. [0003] Whether it is a pure electric vehicle, a fuel cell electric vehicle, or an extended-range electric vehicle, the new energy vehicle can use the hub motor as the main driving force, and even the hybrid vehicle can use the hub motor as a booster for starting or rapid acceleration. Therefore,...
