![]() Using ADC to manipulate LEDs to indicate direction blue on=fwd, orange on=rev, blue and orange off= neutral 4. PWM on High side and turn on/off low side 2. * Date:5/1/18 Revision 6 Written By: Brandon Dyer Description: 1. The video below shows the motor being operated using a potentiometer and the motor controller, and the image below shows the three phase voltage output of the motor controller as it is operating the BLDC motor in the forward direction. The speed and direction of the motor will be controlled by a potentiometer that is connecting to a steering lever (much like what is used in a zero-turn mower). One main focus of this project was to use mostly Texas Instruments (TI) components and software. The motor controller is designed to operate a 1hp Brushless DC (BLDC) motor with a maximum operating voltage and current of 48V and +/-25A respectively. Each motor is operated by its own individual motor controller but will use CAN communications to communicate with the other individual motor controllers. The sole purpose of this project is to design a motor controller that can operate the six individual hub motors that will be used to drive a rover. ![]() Lewelling, Texas Instruments E2E forum respondees, and others, this project was successful. This project was a Senior Design project that me and my team members, Duncan Starr and Grant Reed, had completed while attending the University of Arkansas in Fayetteville, AR.
