More Information
Summary:The invention relates to a iron core of motor comprising a stator iron core layered formed by steel plates and comprising a stator tooth crest, a stator tooth-middle and a stator tooth yoke; a rotary iron core layered by steel plates on one side of stator iron core. The stator tooth crest and the rotary iron core have a additional metal plate compared to the stator tooth-middle; therefore, the thickness along the rotary axis of motor is thicker than the part of stator tooth-middle. And the thickness of stator tooth crest and the rotary iron core along the rotary axis is best to the same with the external leakage part of stator copper wire coiled on the stator tooth-middle. The stator with said structure can reduce the magnetic leakage of external leakage part of copper wire to improve the efficiency of motor, output high power torque, increase the inertia of rotary and reduce the vibration.
