Electric Two-Wheeler

The goal of the project is to design a controller for an alternator being used as a motor. As proof of concept, the entire system will be mounted on a bicycle to assess its performance in the rolling terrain of the Palouse.

=Problem Definition= Design a motor controller that will test the limits of an alternator as a motor; compare its motor capabilities to its generator capabilities. Proof of concept(s): DC generator load for fine control of power output. Electric Vehicle load to test our controller under variable loads.

Specifications
The only initial requirement is that the system performs. That is, by any means available the controller should be able to start and reliably power the alternator under load. Only from that point will we know what our performance values are and thus the margins for improvement.

=Design Considerations= An alternator may make for a great motor for electric bicycles, given their power density, current capabilities, and controllability. This will have to be determined through capable modeling and experimentation.

=Project Learning= Building a control system Simulating different synchronous machine

Simulation


==Machine Test== Magnetization Curve Test Procedure: Turn the machine at constant speed and record Ea as a function of If. Results: gives data to the constant relationship between Ea and ω for all pre-saturation values of If. Rotor and Stator Tests Procedure: Place AC and DC on rotor or stator and use the resulting current outputs to determine Ls, Lr, Rs, and Rr.
