Example Embodiment

[0028] The following is a specific implementation of the present invention for further description:

[0029] The present invention is a new type of disk type permanent magnet composite brushless motor. The device includes a stator 1, a stationary magnetic ring 3, and a magnetic gear outer rotor 4. The magnetic gear outer rotor is used as the rotor of the composite motor and is integrated with the casing. The magnets 6 are evenly embedded in the rotor yoke core 5 along the circumferential direction. The stator 1 adopts a disc-shaped slotted structure, and the static tuning ring 3 adopts a disc-shaped structure, and is placed between the stator 1 and the outer rotor 4 of the magnetic gear.

[0030] Such as figure 1 The structure of the motor is shown: there is an air gap between the stator 1 and the static magnetic tuning ring 3, and there is an air gap between the static magnetic tuning ring 3 and the outer rotor 4 of the magnetic gear.

[0031] The basic principle of the present inv...

Abstract

The invention relates to a disk permanent magnet composite brushless motor. The motor comprises a stator (1), a winding (2), a static magnet adjusting ring (3), a magnet gear outer rotor (4), a rotor yoke iron core (5) and a permanent magnet (6), wherein the magnet gear outer rotor (4) is integrated with an enclosure; the permanent magnet (6) is uniformly embedded on the rotor yoke iron core (5) along a circumferential direction; the stator (1) has a disk slotting structure; the winding (2) is embedded in a stator slot; and the static magnet adjusting ring (3) has a disk structure and is arranged between the magnet gear outer rotor (4) and the stator (1). In the motor, an inner rotor is saved on the basis of the conventional magnet gear structure, so processing technology is simplified, permanent magnet materials are saved and larger vibration and noise which are produced by the inner rotor are also eliminated simultaneously.

Description

technical field [0001] The invention relates to a novel disk-type permanent magnet composite brushless motor, which belongs to the new special motor technology. Background technique [0002] At present, ordinary cylindrical motors have some weaknesses, such as difficult cooling and low utilization of the rotor core; at the same time, mechanical gearboxes are used in many transmission fields to achieve speed-up or speed-down to meet system requirements. However, this also greatly increases the size and weight of the entire transmission system, and the investment cost increases accordingly. In addition, the disadvantages of high noise, low efficiency, low transmission accuracy, and slow response are also its shortcomings. The wear of the gearbox will reduce the system. life and reliability. [0003] Disk motor has its unique advantages. At the same time, the concept of magnetic gear has been gradually promoted, and its application range will continue to expand. Here, the disk...
