Rotating electrical machines, non-oriented electrical engineering steel plates, multi-layer core, methods of manufacturing rotating electrical machines and methods of manufacturing multi-layer core

Abstract

In the morning, the design refers to a rotating electric machine, in which this rotating electric machine includes the State, the rotor, and the State and rotor housing. A is the directional strength {11 ì} <211> of the base steel plate of the non-oriented electrical steel plate included in the stator less than 15, B is the directional strength {111} <211> of the base steel plate of the non-oriented electrical steel plate included in the rotor in the range from 2 to 30, A and B satisfy the relationship B / A > ] ,0, c is the directional strength {411} <011> of the base steel of the non-directional electrical engineering steel plate included in the State, ranging from 2 to 50, D is the directional strength {411} <011> of the base steel of the non-directional electrical engineering steel plate included in the rotor, ranging from 1 to 40, and c and D satisfy the relationship C / D > 1.0.
