Converting common induction motors to low rpm alternatorsInduction motors are commonplace, you'll find them on tools, furnaces, blowers...etc. It is possible to convert them into effective brushless low rpm alternators by installing permanent magnets in the armature. We have performed experiments installing surplus computer hard drive magnets into the armatures. Undoubtedly, a "surplus" magnet is probably not

Vehicle Alternators
Advantages: cheap, easy to find, pre-assembled.
Disadvantages: high rpms required, gears or pulleys needed, low power output, slip rings need maintenance.
Suitability for Wind Power: POOR
The biggest problem with using car alternators for wind power is that they are designed to rotate at too high a speed to be practical in wind power applications without significant modifications. Even a small, seemingly fast windmill might do most of its work at 600 rpm, not nearly fast enough for a car or truck alternator. This means that
