Abstract

The invention relates to a non-rare earth magnet motor, comprising a stator iron core, a varnished wire, a ferrite magnet, a rotor and a bearing. The non-rare earth magnet motor is characterized in that: the stator iron core is made of non-crystal metal and does not contain rare metal; the varnished wire is wound on the stator iron core; the rotor is fixed by the bearing; and the ferrite magnet is fixedly arranged on the rotor. The stator iron core of the magnet motor is made of the non-crystal metal and does not contain the rare metal, so that the risk of increasing the motor cost caused by huge rise in price of raw materials is reduced. The non-crystal metal not only is higher than an electromagnetic steel plate in magnetic permeability, but also further has a characteristic of low iron loss, so that the efficiency of the entire motor is improved and the requirements of energy conservation and environmental friendless are met.

Description

technical field [0001] The invention relates to a motor, in particular to a non-rare-earth magnet motor. Background technique [0002] Magnet motors are usually used in mechanical or electromechanical fields, mainly to realize energy conversion and provide source power. Conventional magnet motors use magnets (rare earth magnets) containing rare metals such as neodymium (Nd) and dysprosium (Dy). As the price of rare metals increases, the cost of electric motors continues to climb. In addition, the electromagnetic steel plate of the traditional magnet motor has relatively low magnetic permeability and high iron loss, which seriously affects the efficiency of the entire motor. How to realize the low-cost and high-efficiency operation of the entire motor has been a problem that those skilled in the art have been paying attention to. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a non-rare earth magnet motor...
