Project Summary

A working 3-phase AC controller is required by the Electric Vehicle Team's E-Bike (Later to be modified for the super bike). Currently, the 3-phase AC controller is very power hungry during operation and sub-optimal in performance. Further, it does not allow for regeneration of the batteries during braking. Ideally the new controller will integrate with the current system - allowing both controls and data monitoring to occur as usual (current). The controller will provide high output power and a high degree of control (resolution) of the power train. Finally, the device should be robust and especially durable for race conditions.

The goals of this project are to analyze the system that is currently in existence for such controls. The device should be designed, working, and installed by Imagine RIT in the spring of 2016. Regenerative battery recharging while braking is a feature that would be ideal to have when the project is complete. The constraints of this project are the budget of $1000 as well as making sure that the controller does not have too strict of optimal condition bounds which would lead to it being too fragile to use for racing. Additionally, the prototype should fit within the current housing constraints. The motor controller should also be compatible with the current subsystems of the E-bike.
