Abstract
A throttle control module for controlling a throttle, comprises: a BLDC motor; a gear train connecting the motor to the throttle; and a throttle position sensor. A PWM module is connected to the throttle position sensor and generates a pulse-width modulation sequence according to the signal from the throttle position sensor and a desired throttle position signal. A decoder module generates commutation logic for the motor based on the signal from the throttle position sensor. A motor controller controls commutation of the motor according to the pulse-width modulation sequence and the commutation logic.
