Abstract

The invention discloses a combined iron core motor which comprises a stator and a rotor. The yokes of the stator and the rotor respectively have a hybrid iron core structure. The combined iron core structure is provided with an auxiliary iron core layer, a non-magnetic-conductive material layer and an auxiliary iron core layer, wherein the auxiliary iron core layer, the non-magnetic-conductive material layer and the auxiliary iron core layer are successively arranged in an R direction of the rotating shaft. The auxiliary iron core layer is a magnetic-conductive component. The non-magnetic-conductive material layer is a non-magnetic-conductive material component. The teeth and the yoke of the stator are integrally formed. Through a composite-layer structure in a manner of adding the auxiliary iron core layers which are made of the magnetic-conductive material at two ends of the non-magnetic-conductive material layer, advantages of small weight of the non-magnetic-conductive material and high torque characteristic of a manufactured motor are kept, and furthermore because the magnetic-conductive material is added, motor inductance is increased and motor current ripple is improved.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a hybrid core motor. Background technique [0002] The coreless motor uses lighter non-magnetic materials as the stator teeth, yoke and rotor yoke, instead of using silicon steel sheets as the stator and rotor core materials in traditional motors, eliminating the cogging torque and iron loss, and reducing the driving force. Power, reducing the heat source of iron loss, so it has the advantages of light weight, good torque characteristics, low loss and high reliability. [0003] On the other hand, this type of motor has no iron core, which also increases the reluctance of the magnetic circuit, and the inductance is very small, which makes the current ripple larger. Contents of the invention [0004] The purpose of the present invention is to provide a motor with a mixed iron core to improve the current ripple of the ironless motor. [0005] The solution of the present ...
