  • Patent number: 10756656
    Abstract: Technical solutions are described for generating an output torque from a multi-winding PMDC motor. An example method includes generating, by a current controller, a first voltage command for a first winding set from a plurality of winding sets of the PMDC motor, the first winding set generates a first current in response to the first voltage command. The method further includes generating, by the current controller, a second voltage command for the second winding set from the winding sets of the PMDC motor, the second winding set generates a second current in response to the second voltage command. The method further includes generating, by the PMDC motor, the output torque based on the first current and the second current.
