Motor Data

24V motor, we will use it at 12V, estimated about 300W

Main process

We need to move the steering shaft to the target angle.

  1. Micro controller reads target position from main computer (Orin) and current position from the Hall effect sensor
    • Micro controller may be a Blue Pill, Teensy 4.0, or one with CAN transceiver builtin.
  2. Calculates PWM % value with PID. Sends PWM 3.3V to H-bridge
  3. H-bridge (MD30C) receives PWM and powers the DC motor
    • ChatGpt said it can't work with 3.3V PWM, just 5V PWM, but the datasheet says otherwise here

H-bridge data

See H-bridge for more details.
