Abstract: A system including memory to store a plurality of sets of values, where each set is used to control speed of a different type of motor. A pulse width modulation (PWM) module receives an input indicating a type of motor sensed in the system, selects a set corresponding to the type of the sensed motor, and generates, based on the selected set, a pulse width modulation signal to control speed of the sensed motor. A speed module receives a requested speed for the sensed motor and generates an output indicating a range of speed corresponding to the requested speed. The PWM module selects, based on the range of speed, a value from the selected set; shifts, based on the selected value, the pulse width modulation signal; and adjusts, based on the shifted pulse width modulation signal, the speed of the sensed motor by adjusting torque applied to the sensed motor.
