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[edit]

Design a motor controller that will test the limits of an alternator as a motor; compare its motor capabilities to its generator capabilities.

The first proof of concept is a DC generator load for fine control of steady state power output. The second proof of concept is an Electric Vehicle load to test our controller under heavy transients.


Alternators have good power density and cost-effectiveness as generators. These power values will give us the specifications for our performance standards when running our alternator as a motor. The controller design will have to be determined through capable modeling and experimentation.

However, 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. From here, we will be able to improve our design, bringing the performance values closer to those of the generator.

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.
