Why should the core of an electric motor be made of a stack of silicon steel sheets? Why not use a large piece?
This will minimize eddy currents. As for silicon steel sheets, of course, the thinner the better.
Because there are some complex calculation formulas, and it involves some professional knowledge, so it is the two purpose to say it directly.
First of all, because of the good magnetic conductivity of silicon steel, so choose silicon steel. 2. fold one by one to reduce the eddy current losses of the core.
