In 2.S994 we made our own “h-bridge” motor controller using MOSFETs to control a motor. We then tried out a commercial bi-directional motor controller on the same motor.
Here are pictures of the setup. I will update with schematics / details on the motor controller later. I believe it was a Pololu product.
Update: Here is information on the MOSFETs in the controller we made in class. Ownership of these two documents goes to Professor Derek Rowell. The commercial controller was Pololu Robotics #713 H-Bridge Driver that uses the Toshiba TB6612FNG dual H-bridge motor controller IC.
