Abstract

A high-speed generator using magnetic powder and a binding material rotor is characterized in that a motor comprises a casing (1), a stator, and a layered binding hybrid permanent magnet rotor, and the stator and a rotor are disposed in the casing (1). Such structure can effectively reduce a heat source in the rotor of the motor and fundamentally solve the problem of overheating of the rotor of the high-speed generator. In addition, such structure ensures the uniformity, integrity and consistency of the rotor of the motor, and can mechanically solve the problem that the permanent magnet is broken by the large tensile stress under the condition of high-speed rotation.

Description

technical field [0001] The invention relates to a high-speed generator using magnetic powder and a binding material rotor. It belongs to the field of motors. Background technique [0002] Due to the high power density and high speed of the high-speed permanent magnet synchronous generator, the volume of the motor is much smaller than that of the medium and low speed motors with the same output power, so it can effectively save materials; the small size of the high-speed motor makes it have a small moment of inertia and has a relatively Fast dynamic response capability; and because the high-speed motor can be directly connected with the prime mover, the traditional mechanical transmission device is omitted, so the efficiency of the traditional system can be improved and the noise can be reduced. In particular, permanent magnet generators have the advantages of high energy density, simple structure, no excitation loss and high efficiency, and are especially suitable for mediu...
