Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2017073902
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary electric machine capable of driving a three-phase motor without using a brush.SOLUTION: A rotary electric machine 10 comprises: an inner rotor 11; and a first electric motor 31 that has respective phase rotor coils 22u-22w provided in the inner rotor 11 and that serves as a three-phase motor. The rotary electric machine 10 comprises a plurality of phase power feeding parts 41u-41w corresponding to the plurality of phase rotor coils 22u-22w. The u-phase power feeding part 41u feeds a power to the u-phase rotor coil 22u by using electric field coupling type non-contact power transmission via both u-phase coupling capacitors Cu1 and Cu2. The v-phase power feeding part 41v feeds a power to the v-phase rotor coil 22v by using electric field coupling type non-contact power transmission via both v-phase coupling capacitors Cv1 and Cv2. The w-phase power feeding part 41w feeds a power to the w-phase rotor coil 22w by using electric field coupling type non-contact power transmission via both w-phase coupling capacitors Cw1 and Cw2.SELECTED DRAWING: Figure 3
