ROTARY ELECTRIC MACHINE, METHOD FOR MANUFACTURING THE SAME, AND WIND TURBINE GENERATOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a rotary electric machine capable of restraining an increase in its material cost and attaining a desired efficiency.

SOLUTION: The rotary electric machine is equipped with a rotator and a stator surrounding the rotator. The stator includes a yoke core laminated by folding a band-like non-directional electromagnetic steel plate in a circular manner and a plurality of tooth cores which are arranged in the peripheral direction of the yoke core and in which one end is fixed on the inner periphery side of the yoke core and the other end faces the rotator. Each of the tooth cores is formed of a member with directional electromagnetic steel plates laminated, which are independent of each other. The magnetization easiness direction of the each tooth core meets the diametrical direction of the yoke core.
