摘要 |
A control circuit for a reluctance machine having two mutually movable parts and at least one inductive phase winding adapted for a certain maximum drive current value. The method includes detecting when a phase winding is in a non-drive mode; causing a test current, having a second maximum value lower than said certain maximum value, to flow through the phase winding and through a current sensor when the winding is in the non-drive mode; and establishing a mutual position in dependence of the output of said current sensor.
