Document Type and Number:
WIPO Patent Application WO/2018/047483
Kind Code:
A1
Abstract:
To provide a rotary electric machine and a non-contact generator which have good magnetic efficiency, little magnetic flux leakage and in which a countermeasure against cogging torque has been implemented. A rotary electric machine 1 is provided with: a rotary body 11 having a permanent magnet that rotates on a predetermined rotation axis due to a Lorentz force generated according to the rotation or movement direction of a moving body, said rotary body being arranged opposing the moving body in a separated manner above a main surface of the same, said moving body being a conductor that rotates or moves; and an initial drive force provision part 12 which, if the moving body starts to rotate or move when the rotary body is not rotating, provides an initial rotary drive force to the rotary body.
