1. An apparatus comprising:

  • a controller configuredto identify a desired speed for an electric motor during operation of the electric motor;

    to identify a duty cycle for the desired speed;

    to identify a voltage to cause the electric motor to turn at the desired speed based on the duty cycle identified for the desired speed;

    to generate the duty cycle as a duty cycle command for the electric motor;

    to generate a voltage command based on the duty cycle command;

    to generate the voltage as a regulator voltage for a voltage regulator circuit based on the voltage command; and

    to apply the voltage to the electric motor during operation of the electric motor.
