NOVELTY - The coreless motor has a magnetic coil that is made up of two components of permanent magnets. The ironless core coil is arranged in a magnetic field and in a radial magnetic field through a rotating shaft, and the rotating shaft is arranged at the interval of two permanent magnet blocks. Two permanent magnets are arranged in the main portion to form the magnet ring composed of multiple layers of graphene sheets coated with neodymium iron boron, and the coil is formed by winding the graphene wire. USE - Coreless motor for electric vehicle. ADVANTAGE - The service life of coreless motor is prolonged. The production cost of motor is reduced. The scale of production is rapidly formed, so as to promote the industrialization and marketization of electric vehicles.
