Title: Drive device using magnet coupling
Inventor: MIYAZAKI HIROYUKI
IPC: H02K49/10
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To enable detection of step-out during the acceleration period of a drive side magnet in a manner similar to as during a constant speed period. SOLUTION: Correlation between the controlled variable and the number of revolution of a drive side magnet 14, when a load is not applied, is stored beforehand in a storage part 22b. A control means 22 detects, at prescribed time intervals, the actual number of revolution of the magnet 14 driven by a motor 12 with a rotation detecting means 20. At this time, the number of revolution with no load to the controlled variable of the motor 12 is obtained, on the basis of the correlation stored in the storage part 22b. The difference between the number of revolutions at no load and the actual number of revolution is obtained as slippage. The difference between the latest slippage and the slippage preceding by a previously determined time from the latest slippage is obtained. When the obtained difference of the slippage exceeds a previously set reference value, it is deemed that step-out of the drive side magnet 14 and a slave side magnet 18 has occurred.
