Title:
TRANSFER DEVICE AND TRANSFER METHOD FOR OBJECT BEING HANDLED
Document Type and Number:
WIPO Patent Application WO/2020/158264
Kind Code:
A1
Abstract:
This transfer device comprises: a coil drive unit 212 and drive circuit 50 which apply a voltage to a plurality of coils 25 which generate a thrust for transferring the permanent magnet 10; a position estimation unit 210 which estimates the position of the permanent magnet 10; and a route information storage unit 211 which stores route information of the permanent magnet 10. The coil drive unit 212 and the drive circuit 50 apply a drive current to a predetermined coil 25 on the basis of route information stored in the route information storage unit 211 and the position of the permanent magnet 10 estimated by the position estimation unit 210, and a position detection current is applied to the nearest coil 25 which is estimated to be the nearest to the permanent magnet 10, and the coils 25 in the area surrounding the nearest coil 25.
