Week 11: 10/31 - 11/7
This week:
All decisions were made with Dr. Furman's approval:
-> Purchased one KBL controller for controls team to run the necessary tests. The controller will arrive on Thursday 11/8 by 10:30 AM. (Paid a total of $100)
-> Purchased 3 XOFO motors. Motors will take 3 weeks to be manufactured and shipping will take approximately a week. We expect to have motors before the end of the month, most likely after Thanksgiving. (Paid a total of around $700)
-> We are scrapping previous CAD design of the shaft. Project scope has been changed by Dr. Furman. He preferred us not to take apart the motor to replace the shaft and casing. Dr. Furman was fine with leaving the double-sided shaft sticking out, which made our team's decision easier.
-> We are not doing any changes to the motor that we purchased, as requested by Dr. Furman. Originally we are planning to design a housing for the motor to attach airless tire on it. Instead, we are designing a rounded steel case that will house the motor and become our wheel.
-> For our new shaft design, we are designing a threaded axle that will connect one motor on each side of that shaft. This is done to help distribute the weight throughout the axle, rather than having all the weight sit on two sheets of metal from bogie interaction design. We will be meeting with them on Wednesday to discuss further.
Upcoming Week:
-> Deliver KBL controller to controls team.
-> Continue CAD designs
-> Look into rapid prototyping
-> Run FEA analysis
-> Look into what material our shaft and case would be.
-> Find a machine shop that will cut our design in the future and get expert recommendations.

Full Scale Motor Team,
ReplyDeleteI am looking forward to seeing some of your designs, and finally some testing results on your motors and controllers.
PLEASE be sure to read the motor / controller instructions carefully. Last year, we had a team buy a motor and controller, and hardly follow the directions which resulted in failure.
Lots of work to be done, keep it up
