Abstract
Provided is a multi-phase motor switching device capable of switching a plurality of coil parts constituting the phase coils of a multi-phase motor between a series connection and a parallel connection. A multi-phase motor switching device is used in a multi-phase motor provided with a first-phase coil, a second-phase coil, and a third-phase coil. The multi-phase motor switching device includes: a first switching unit configured to switch a plurality of first coil parts constituting the first-phase coil between a series connection and a parallel connection; a second switching unit configured to switch a plurality of second coil parts constituting the second-phase coil between a series connection and a parallel connection; a third switching unit configured to switch a plurality of third coil parts constituting the third-phase coil between a series connection and a parallel connection.
