Refrigeration there: with completely independent intellectual property rights of breakthroughs in research and development and industrialization of coreless rare earth permanent magnet motor, this symbolized our country has made positive progress in the field of high efficiency and energy saving motor. Held on November 28, the national development and reform commission of coreless rare earth permanent magnet motor to promote the scene in the meeting, the participating experts think, special mechanical and electrical co., LTD. Shenzhen Antoine mountain home-grown coreless rare earth permanent magnet motor has realized the high efficiency and energy saving in China's major breakthrough. The product technical breakthrough in the "big three", namely the axial magnetic field structure, unique and molding process of the distribution of stator winding, rotor without iron core; Has a "big four" advantage performance, that is, high efficiency and energy saving, light material saving, speed and reliability.Refrigeration letters according to reporter understanding, rare earth permanent magnet coreless motor is on behalf of the industry's future development direction of a new type of special motor, with no iron core, brushless, no magnetic damping, rare earth permanent magnet generator technology, using silicon steel sheet and changed the traditional motor stator winding structure, combined with the independent research and development of electronic intelligent frequency conversion technology, make the motor system efficiency is increased to more than 95%. At present, our country with independent intellectual property rights of coreless rare earth permanent magnet motor r&d and industrialization level in the world, product application prospect. According to preliminary estimates, if there is a third alternative in new motor, nearly 50 billion KWH can power saving a year, saving the silicon steel 500000 tons, 20000 tons of copper, can create nearly one hundred million yuan output value, economic benefit and social benefit is very considerable.
