An electric drive includes a rotatable shaft, a first drive member, and a second drive member, and is supplied with power from a controller. The controller is operable to supply a first power from a power electronics converter, and a second power that is line power. Supplying the first power individually to the first drive member results in a first shaft speed and first output torque, supplying the second power individually to the second drive member results in a second shaft speed and second output torque, and supplying the first and the second drive members with power at the same time results in a third shaft speed and a third output torque.
