1. A system for control of direct current (DC) motors, comprising:

  • a power drive coupled to a brushless DC motor; and

    a micro control unit (MCU) configured to control commutation of the brushless DC motor based upon shaft speed of the brushless DC motor, where the MCU transitions between a motion-based commutation mode and a time-based commutation mode in response to a comparison of the shaft speed with a predefined threshold.
