Favourite answer. In addition, a car alternator functioning as a motor has more versatile control than a conventional brushless motor, and it can have more power and torque at high speeds than a conventional brushless motor of similar size due to its adjustable field. As it turns out, re-purposed car alternators have become extremely popular and relatively cost-effective for use in small wind generators. Alternators usually have internal voltage regulators. car alternator to operate as a low speed generator for wind or hydro power generation. Also, the relatively small amount of power needed so the field windings can become an electro-magnet, can be sent to the armature via a pair of small brushes that would ride on slip rings on the armature instead of bars. A car alternator that can be readily converted to a powerful motor costs about $100.00, but a conventional brushless motor that produces about the same power output typically costs far more -- well over $500.00 and is often more difficult to obtain with long order lead times. This should be changed to negative ground on the battery and wire from the starter solenoid should go to the battery positive terminal. That’s how the electricity is directed out of the generator and to the rest of the car. However, consider their usual use case: attached to a car engine that’s probably mostly running around 1000-4000 RPM via a belt that gives about 4x speed multiplier on the alternator. According the wiring diagram I thought it would be an easy job!! This is called a Hybrid Brushless Motor since it has a combination of brushless power drive current and a small brushed field current.
