Title: MOVABLE BODY SYSTEM
Abstract:
The present invention detects a relative position of a coil in a short time and ensures a power feed time period, in an elevator in which power is fed to a cage while the cage is stopped. A movable body system according to the present invention is provided with: a movable body; a first power transmitting device and a second power transmitting device provided around the movable body; a first power receiving device which is provided on a first surface of the movable body and to which power is fed from the first power transmitting device in a noncontact manner; and a second power receiving device which is provided on the first surface and to which power is fed from the second power transmitting device in a noncontact manner, wherein the coupling rate of the first power transmitting device and the first power receiving device and the coupling rate of the second power transmitting device and the second power receiving device are reciprocal due to positional shift of the movable body, and power is fed by the first power transmitting device and the second power transmitting device.
