High Density Power Motor Team

The main focus this week for the motor team was to work with bogie interaction team to integrate the motors, motor's wheels, and axle onto the drive bogie. During this integration process, both teams ran into quite a bit of an issue with manufacturing the hole on the drive bogie for the axle to be fitted into. It was originally planned so that hole sizes of approximately 1.010 inches were to be water jet cut into the four supporting plates of the drive bogie; however, bogie interaction team wasn't able to have those holes made during the water jet process. This means that we had to use a drill press to create the 1-inch holes. The problem with drilling the one-inch holes manually is that it would be quite difficult to have all four holes on the four plates to align properly for the axle to slide through. To resolve the issue, we filed and milled out the holes to a greater size for the axle to be fitted into. To further secure the axle, we incorporated face mounted lock colla...

This Friday we have our final presentation, and some small adjustments to the motor. For cable management, we 3D printed a small fender for our motors' wires to fit through. Our presentation is linked below.

The motor casings and the new shaft came in. We tested the controls with the casings on one motor with the shaft attached and it was able to move just fine. However, we're worried that the torque caused by the friction between the wheel and the ground will cause the shaft to loosen up and unscrew itself from the motor. We talked to Professor Furman, and we came to the conclusion that adding two screws to the bogie on either end of a lock washer that came with the motor will be enough to absorb the torque and keep the shaft from unthreading.
