2. Overall Objective
Build a test rig that is capable of quantifying the performance of a wireless power transmission device, while simulating operating conditions for the device

3. Customer Needs

4. Engineering Specifications

5. Test Rig Design

6. Final Product Pneumatic air cylinders clamp device in place
Linear stage allows vertical motion to set gap distance
Generator clamp sits on turntable to allow induced torque measurement
Motor clamp suspended from load cell to allow compression force measurement

7. User Interface

8. Calibration Challenges
Thermocouples
Difficulty in holding water at constant temperature for accurate measurements
Counter
Could not calibrate with Hall Effect sensors until device was complete
Difficulty in using tachometer with device

9. Calibration Results

10. Budget Initial Budget: $1,000 Final Expenses: $813.29
Final expenses slightly above initial estimate because of shipping costs

11. Conclusions
Input power and output power are not measurable because P12026 did not provide leads and the voltage was not within measurable range
The generator RPM cannot currently be measured because the Hall Effect sensor is not working properly

12. Future Work Recalibrate thermocouples with better temperature source
Make/buy amplifier for 50 lb load cell
Modify data output to Excel
