Project Definition Overview

This project focuses on the development of a Electric Motor Test Bench for RIT's Electric Vehicle Team. This project is designed to test the capabilities of the motor of an electric vehicle when used in conjunction with a motor control unit. The test bench will apply a dynamically variable load to the motor and controller, and then measure how these components react to the given conditions. REV(05-12-2016)

Overview of Status

A dynamic load test bench was developed and tested. The project was an overall success. A few redundant systems were not able to be completed, and user documentation was not as flushed out due to time constraints caused by budgetary issues.

Testing

Subsystems were individually tested and then integrated. Sensing subsystems are performing as planned, though a smaller range current sensor would be an improvement to the system.

Budget

Through sponsorship, our budget expanded significantly. The final Bill of Materials below shows the totals spent for each subsystem. In total almost $26k was fund-raised through the course of this project.

Scheduling

The original plan for MSDII was changed significantly through the course of this semester. Due to major issues with using the donated golf cart motor as a Unit Under Test, the plan ended up behind by 3 weeks by week 8. The team reassessed out schedule at that point, settling on the final schedule shown, and successfully completing the project on time.

Problem Tracking

The team kept an accurate list of major project problems, which were regularly discussed among the whole team, as well as presented at design reviews. This problem tracking let us each individually deal with problems, while remaining accountable to the team as a whole.

At this time, there are no major problems left to be fixed, as the test bench is in a working state.
