The stepper motor controller FPGA generates 4 coil driving signals and receives a stepper end input.

stepper motor board

Stepper motor

The stepper motor is a Nanotec SP3575M0906-A.

It has a step angle of 7.5°, and as such 48 steps per turn.

The cables are connected as follows:

Signal Color
phase 1 white
phase 2 blue
phase 3 red
phase 4 yellow
power brown, black

FPGA design

The stepper motor controller has to generate the 4 phases to turn the kart's steering wheels to the desired angle.

To start, the design environment has to be downloaded.
