摘要：
To prevent demagnetization of a permanent magnet synchronous rotating machine, a rotating machine control device according to the present invention is a rotating machine (5) control device comprising: a power converter having a switch part (Sup to Swn) on each of a positive side and a negative side for each phase; and short circuit detection unit (36) for detecting a short circuit of the switch part (Sup to Swn), wherein a command to turn on positive-side switches and negative-side switches of a plurality of phases of the switch part (Sup to Swn) is issued in the case where the short circuit detection unit (36) detects the short circuit.
