For stainless steel alloys, the lower the surface roughness, the smoother the surface, the more difficult it is for foreign bodies to attach, and the lower the probability of local corrosion. Therefore, stainless steel should be as finished as possible.

For permanent magnet motor, the core is a very important part of the motor, for the selection of core materials, it is necessary to fully consider whether the permeability can meet the needs of the permanent magnet motor.

The hybrid propulsion system is part of the Airbus Group's decarbonisation roadmap, but Airbus Group is not alone in its efforts to become more environmentally friendly in the aviation industry.

Zhongshi Industrial Research Institute said that all kinds of products motor generally use non-oriented silicon steel production, at present, China's large motor (thermal power, wind power) is trying to use non-bottom oriented silicon steel as raw material production motor, the future is expected to achieve technological breakthroughs, for oriented silicon steel to provide new growth space.

With the development of electric vehicles, the performance of the motor is also put forward high requirements, high energy efficiency, high power density is becoming more and more important.

The purpose of this study was to analyze the fatigue life and fatigue crack initiation behavior of electrical steel plates under different edge conditions, and to compare the edge surfaces obtained by four different cutting methods, including polishing, wire cutting, laser cutting and shear cutting.

The rapid rollout of renewable energy and electric vehicles poses some challenges. One of the major challenges is whether the existing grid infrastructure can handle these modern technologies.

The stator of asynchronous motor is composed of stator core, stator winding and frame. The stator core is a part of the magnetic circuit of the motor, which is used to insert the stator winding and provide the magnetic path.
