P08203: DC Motor Dynamometer/public/
This is a list of some informal notes that I think may help get the team started. This is no particular order or specific organization.
- 100 kg steer motor = 10 kg drive motor
- 10 kg steer motor = 1 kg drive motor
- Motor Specs
- Previous Team was given the task of designing both a chassis dyno and a motor dyno. Because designing both proved to be too large of a scope this project will focus specifically on creating just a motor dyno.
- Students will determine to what extent the previous design needs to be modified (i.e. complete rebuild or some rebuild and some modification). Most likely this will involve some rebuild and some modification to the previous design but this is not a constraint to your design.
- When developing concepts it is important to keep in mind the critical non trivial design characteristics (the motor platform, sensing techniques, etc.). These critical areas should be designed and considered first and then the trivial components can be designed and adapted to that design. This will help to make sure that each sub function will work together.
- Some design flaws to the previous design:
- Non-robust motor platform. The platform that was design would bend under certain loads and therefore did not meet the required range of scalability.
- Control board fried due to non-monitored inputs. Therefore they were not able to test the design.
- Subsystem designs (i.e. controlling system, braking system, etc.) were independent designs and did not work well together.
- Pros- possible pieces for modification
- Possibly the braking system, but may not be capable of being scaled down to the required level. It may be too large for the smaller applications.
- Coupling design
- Ability for the system to chuck on variable output shafts
- Control board design. From what was explained, in theory, the design would have worked, but it was never fully tested because the board got fried due to a static discharge to the board.
