Abstract

The invention provides a disc-type low-speed large-torque composite motor based on a magnetic wheel gear, which is formed by combining a disc-type motor with a magnetic wheel gear. The composite motor is simple in structure, easy to manufacture, small in volume and light in weight; the manufacturing cost is reduced, and the efficiency and the capacity of the motor are improved; and meanwhile, thecomposite motor is small in vibration, low in noise and high in stability. The composite motor comprises a supporting axle, an enclosure, outer rotors of the magnetic wheel gear, a stator, permanent magnets, a rotor yoke iron core, a winding, stator slots and magnetism regulating blocks; a disc-type stator is fixed on the supporting axle; two outer rotors of the magnetic wheel gear are rotatably arranged on the supporting axle, and integrated with the enclosure; the left side and the right side of the stator are respectively provided with a stator slot; the magnetism regulating blocks and a stator tooth are connected to form an integrated structure with the stator, and an air-gap exists between the adjacent magnetism regulating blocks; and the outer rotor end surface of the magnetic wheelgear opposite to the side surface of the stator is provided with the permanent magnets which are evenly embedded in the rotor yoke iron core along a peripheral direction, and the stator and the outerrotor of the magnetic wheel gear form a mirror symmetrical structure at the left side and the right side in an axial direction.

Description

technical field [0001] The invention relates to a disk-type low-speed and high-torque composite motor based on magnetic gears, which belongs to new special motor technology. Background technique [0002] At present, cylindrical motors with ordinary radial magnetic fields 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] Magnetic gear is a new type of gear structure, which has the advantages of low noise, maintenance-free, high reliability, large torque tr...
