An electric machine unit has an electric machine with two phase groups of at least one phase each and having a power converter, the power converter having two half-bridge groups of at least one half-bridge in each case, each phase group being assigned one half-bridge group, so that one half-bridge is provided per phase connection of the electrical machine. The power converter has DC voltage terminals which are configured for connection to an energy storage, the phase terminals of a first phase group each being connected via an AC switch to the respectively associated half-bridge of a first half-bridge group, the phase terminals of a second phase group each being connected to the respectively associated half-bridge of a second half-bridge group, DC-voltage-side terminals of the half-bridges of the second half-bridge group each being connected to the DC terminals via a DC switch.
