摘要： When there is a breakdown in either one of first and second power converters supplying electrical power to a multi-winding motor comprising a wind-up mechanism, a rescue operation can be safely and reliably carried out by using the remaining power converter. A wind-up mechanism comprises a two-winding motor having first and second windings, and, during normal operation, power is supplied to the first and second windings from first and second inverters respectively. When the first inverter has broken down due to excessive current, first and second contactors are switched off, and a third contactor comprising a short-circuiting unit is switched on. Consequently, both windings receive power from the second inverter, enabling the rescue operation to be carried out without causing vibrations.
