Abstract

The invention provides an anti-flux leakage low-loss driving motor, which comprises a stator and a rotor, wherein the stator comprises a stator iron core and stator windings; the rotor comprises a rotor iron core and rotor magnetic steels; the stator iron core comprises an annular stator iron core yoke ring base body formed by non-oriented silicon steel laminations and multiple stator iron core tooth inserts formed by oriented silicon steel laminations; the rotor iron core comprises an annular rotor iron core base body formed by non-oriented silicon steel laminations and multiple rotor iron core inserts formed by oriented silicon steel laminations. The oriented silicon steel lamination with higher permeability is used for replacing the non-oriented silicon steel lamination in the rotor polarization direction, and a stator pole shoe also uses the oriented silicon steel lamination. Thus, in a large current condition, the saturation flux density is high, the loss is reduced, the driving motor efficiency is improved, and a large-torque low-loss driving motor is thus realized.

Description

technical field [0001] The invention relates to a motor, in particular to an anti-flux leakage low-loss drive motor. Background technique [0002] At present, cold-rolled non-oriented silicon steel is used to design and manufacture drive motors, but with the continuous development and improvement of new energy vehicle technology performance. Higher requirements are put forward for the driving motor of new energy vehicles. The driving motor needs high power density, high torque, high power, high speed and low loss. In order to meet these demands, the drive motors have to be made larger, heavier, more expensive, and have higher losses, all of which violate the long-term development goals of environmental protection, energy saving and emission reduction. In order to meet the high requirements of the drive motor, the use of the existing technology will increase the volume and weight of the motor, increase the cost and increase the loss. Contents of the invention [0003] The...
