For this week, not much can be said, I met with randy to further discuss braking options, and it is becoming increasingly clear that we are going to be limited on size. For the motor that I recently got a bid for, I am still working to figure out if it is capable of handling the back emf needed for engine braking as well as determining where it will become to hot from the process. In addition, I am working to fit a band brake to work with the motor in the bogie assembly, but tolerance is still an issue.
In addition, I have rework the motor cad model to better resemble the new motor that I have chosen, I am still getting a few of the detail modeled and will apply it to the master cad model later this week. With the reworking of the motor, the mount, shaft, and gear will have to be alter to handle the different size for the output shaft of the motor,. The gears for replacement have already been selected of the McMaster Carr website and will be added to the bill of materials.
