[QUOTE="oexing, post: 108485, member: 1493"] Sorry, Norman, to disagree regarding motors or generators, no essential difference. Don´t use starter motors for reference, these are an extremely specialized application for hundreds of amps and breaking down supply voltage when activated in cars or bikes. You can test the good old car DC dynamos for function by hooking a battery to them: They will run as motors - but not overly strong at that. So you can use DC motors for dynamos, like for small wind generators . Same goes for brushless motors as alternators. You just have to hook a three phase motorcycle regulator on them to get DC for your battery. You mentioned your considerations with some Honda permanent magnet alternators, millions of this type are daily assembled on current models on about all makes. Just looking at Ducati alternators, they had both types, the magnetic rotor inside, the coils around it. And the other more current type with static coils inside and the magnets in a kind of flywheel around the coils. But the principle is the same : A rotating magnet produces the field wherein coils generate the voltage, no brushes required, simple, even suitable for in oil operation.
