Week 2 (Feb 9 - Feb 15)

Our team is delayed on our Gantt chart. However, this is a good opportunity to revise our BOM so we can get it approved. One of the items that we will need is a DC motor that can produce enough torque to move our Tilt mechanism. Oriental Motor has motors that can supply the torque, however they are limited in their offerings from what we have seen. Groschopp is another company that manufacturers motors and they are able to supply us with a motor with a high range of customizability and torque.

We have calculated that the needed continuous torque needed to move the tilt mechanism was 644 in lbs. They are able to supply a motor that can operate at 650 in lbs at 15.8 RPM. This would be more than acceptable considering that the tilt mechanism would slowly tilt to keep the cabin stable.

As we look at the graph we can also see that operating the motor at this speed and torque would give us a high motor efficiency. It would be close to 75-77 percent.
