Why should the stator and rotor core of asynchronous motor be laminated with silicon steel sheet?
Eddy current loss and hysteresis loss are reduced. Reduce core heating.
Because the winding through the current will produce an induced magnetic field, induction magnetic field in the iron core to form induction electromotive force, the induction current.
The silicon steel sheet can reduce the eddy current loss of the iron core. Air gap is to ensure that the rotor in the rotating state to ensure the transfer of magnetic force.
The multilayer silicon steel sheets are insulated from each other to reduce the over-current area and reduce heating.
