Abstract
A short detection apparatus configured to detect a layer short in a motor in which a plurality of sets of multi-phase windings are independently disposed in a stator includes an acquisition unit configured to acquire electricity information corresponding to windings of individual phases in the sets of the multi-phase windings; and a determination unit configured to determine, based on the electricity information which the acquisition unit acquires with respect to windings of a mutually identical phase in the sets of the multi-phase windings, whether a layer short occurs in any one of the windings of the mutually identical phase.
