Document Type and Number:
Japanese Patent JP6852799
Kind Code:
B2
Abstract:
A radial-gap-type rotary electric machine, a production method therefore, a production device for a rotary electric machine teeth piece, and a production method therefore can achieve a high efficiency and have excellent productivity. A radial-gap-type rotary electric machine includes a rotation shaft, a rotator including an inner-peripheral-side rotator iron core rotatable around the rotation shaft and an outer-peripheral-side rotator iron core arranged on an outer peripheral side of the inner-peripheral-side rotator iron core and rotatable around the rotation shaft, and a stator disposed between the inner-peripheral-side rotator iron core and the outer-peripheral-side rotator iron core. A permanent magnet is provided on at least one of an outer-peripheral-side surface of the inner-peripheral-side rotator iron core and an inner-peripheral-side surface of the outer-peripheral-side rotator iron core. The stator includes a stator iron core including teeth formed of laminated bodies where amorphous metal foil strip pieces are held with mutual friction.
