The invention discloses a multigap series magnetic disc-embedded type motor, which comprises an end cover, a stator, and a rotor. The rotor consists of a group of disc shaped rotor sheets overlapped on the coaxial direction of the motor in a spacing way; all the rotor sheets are formed with same magnet strings of a multigap series magnetic structure on the polar directions of each corresponding magnet on the coaxial direction; base materials with low magnetic permeability are adopted as the rotor sheets; the stator consists of a group of disc shaped stator sheets overlapped on the coaxial direction of the motor in a spacing way; base materials with low electric conductivity are adopted as the stator sheets; the stator sheets and the rotor sheets are embedded and assembled into a disc-embedded structure in a spacing way by gaps; and gas flow circulating channels are arranged between the rotor, the stator and the end cover. The motor has larger power-volume ratio and power-weight ration, small eddy-current loss and good radiation effect. Moreover, the motor is suitable for electric automobiles to use in particular.
Description
technical field [0001] The invention relates to a new motor, especially a motor with high energy density and low eddy current loss. The motor uses a stator base material with high electrical impedance, a rotor base material with low magnetic permeability, and uses a multi-gap series magnetic structure and an embedded disc structure to reduce the eddy current loss of the motor to a very low level. The multi-gap series magnetic structure makes the motor The magnetic force is fully utilized to achieve very high power density, improve efficiency and reduce raw material consumption. Background technique [0002] Today, when energy conservation and environmental protection are advocated, higher requirements are put forward for the volume, weight, efficiency, eddy current loss and material consumption of the motor, especially the advent of the era of electric vehicles, so that the power of the motor is A bottleneck has been encountered. The disadvantages of current motors include...
