Coreless motor

Abstract

The present invention discloses a coreless motor. The coreless motor comprises a magnetic tent, a coil and a commutation controller. The magnetic tent is formed by two parts of permanent magnets, N poles of one part of the permanent magnets face the internal portion of the magnetic tent, and S poles of the other part of the permanent magnets face the internal portion of the magnetic tent; and a coreless coil is arranged in the magnetic tent with a radial magnetic field through a rotation shaft. The two permanent magnets forming the magnetic tent are formed by a graphene sheet plated with neodymium iron boron, and the coil is formed by winding a graphene lead. The coreless motor has characteristics of collection magnetism coreless motor for realization of a three-dimensional motor magneticfield and high work efficiency, overturns a traditional mode that a current motor is mainly made of metal materials, is suitable for low-carbon economy development, generates new features of energy saving, wide application of high technologies in a motor industry, and is more suitable for technical requirements of a future energy-saving and emission-reduced motor industry.

Description

technical field [0001] The invention relates to a motor technology, in particular to a coreless motor. Background technique [0002] Rare earth permanent magnet ironless motor is a new type of special motor that represents the future development direction of the motor industry. It adopts ironless, brushless, non-magnetic damping, and rare earth permanent magnet power generation technology, which changes the use of silicon steel sheets and winding wires in traditional motors. The stator structure, combined with the self-developed electronic intelligent frequency conversion technology, increases the efficiency of the motor system to more than 95%. The rare earth permanent magnet ironless motor is a major innovation, and it has achieved "three major" breakthroughs in technology. First, compared with the traditional radial magnetic field structure design, it adopts the axial magnetic field structure design, which greatly improves the power density and torque. Volume ratio. The...

Problems solved by technology

[0003] Rare earth permanent magnet ironless motor is a brand-new product, and the market is being cultivated. Therefore, there are still many difficulties and problems in its promotion and application: first, the social awareness is not high

In addition, there is a lack of policy incentives

High-efficiency and energy-saving motors have market obstacles such as high initial cost and information asymmetry, and the state needs to introduce relevant incentive policies to leverage the market and cultivate the industry

[0004] In summary, although the rare earth permanent magnet ironless motor is a new type of special motor representing the future development direction of the motor industry, and has very considerable economic and social benefits, due to the existence of new technologies, new processes, new High-cost issues that affect market start-up and industry cultivation caused by raw materials, so the policy dependence is strong, and the promotion process is not ideal
