Problems solved by technology
In the prior art disc-type coreless permanent magnet generator, the permanent magnets in its structure are distributed laterally. Therefore, due to the limitation of the radial cross-sectional area of the moving disc, the problems of large motor diameter and low efficiency generally exist. For example, a kind of permanent magnet generator is disclosed in the international patent W02009 / 034990A1, and its shortcoming is: owing to be subjected to the limitation of radial circle area, make bigger power, multi-magnetic pole, low speed, higher voltage, the power generation of frequency When the motor is machined, the diameter of the motor will be designed very large to meet the radial area required for the permanent magnet and the ironless coil, and the structure is more complicated, the volume is large, and the production cost is high.

Abstract
The invention provides a multilayer iron core coil-free permanent magnet motor, belonging to the technical field of generating equipment or energy-saving motors. The multilayer iron core coil-free permanent magnet motor is characterized in that an central hole of a rotor is fixed on a spindle; the radial circle area is internally provided with N circular grooves; an inner wall of each circular groove is provided with a permanent magnet which rotates along with the spindle; a stator center is provided with bearings for supporting the spindle; the longitudinal circle area is internally providedwith M coil racks; each coil rack is internally provided with stator windings which are led out by guide lines; each pair of magnetic poles are internally provided with one coil pitch fraction formedby F coils in longitudinal arrangement; 20+F coil pitch fractions are connected in series to form one layer of toroidal coil; three layers of coils are overlaid and pressed to obtain one three-phase stator winding; and a design containing N circular grooves, M coil racks, a pair of conjoined multilayer rotor permanent magnets and the stator windings can be used to improve the output power of a motor with the same diameter by several times. The multilayer iron core coil-free permanent magnet motor can be applied to the technical fields requiring for transmission such as war industry, spaceflight, wind power, electromobiles, generators, electric motors, machinery and the like, and has a wide applied range and development potential.
Description
Multi-layer Ironless Coil Permanent Magnet Motor technical field The invention relates to a multi-layer coreless coil permanent magnet motor, which belongs to the technical field of clean energy wind power generation equipment or energy-saving motors, in particular to a super high-efficiency wind power generator. Background technique In the prior art disc-type coreless permanent magnet generator, the permanent magnets in its structure are distributed laterally. Therefore, due to the limitation of the radial cross-sectional area of the moving disc, the problems of large motor diameter and low efficiency generally exist. For example, a kind of permanent magnet generator is disclosed in the international patent W02009 / 034990A1, and its shortcoming is: owing to be subjected to the limitation of radial circle area, make larger power, multi-magnetic pole, low rotating speed, the power generation of higher voltage, frequency When the machine is used, the diameter of the motor w...
