Abstract
A controller performs, in a first mode, a first operation for controlling composite electromagnetic force of electromagnets such that a target member moves within a predetermined moving range, and a second operation for acquiring temperature drift correlation information indicative of a correlation between a reference value and an input-output characteristic of a position sensor, based on the reference value and the input-output characteristic of the position sensor in the first operation. The controller performs, in a second mode, a third operation for controlling the composite electromagnetic force of the electromagnets according to a signal level of a detection signal from the position sensor, and a fourth operation for compensating the input-output characteristic of the position sensor in the third operation, based on the temperature drift correlation information and the reference value in the third operation.
