Problems solved by technology

The sides of the upper and lower insulating frames 12', 14' opposite to the silicon steel sheet group 10' are provided with protective edges 102', 104' similar in outline to the silicon steel sheet group 10', and the protective edges 102', 104' are connected to the silicon steel sheet group 10'. The steel sheet groups 10' are engaged with each other so that the upper and lower insulating frames 12', 14' and the silicon steel sheet group 10' are mutually positioned. , 104' are plastic materials, its strength is not enough, it is easy to deform, therefore, the positioning of the silicon steel sheet group 10' and the upper and lower insulating frames 12', 14' is unstable
