I have had this on my mind for a while now. But what is considered better or more acceptable. A standard alternator or a permenant magnet generator (3 phase stator, magnetic rotor and voltage regulator)?
Pros to an alternator is internal or external regulator, can be turned on and off manually. Voltage regulator will detect when battery low and charge automatically.

Cons. Belt driven, takes power to make power (field current)

Permenant magnet generator.
Pros. Simple, belt or direct drive, no parts to wear out.

Cons. Cant turn it off, any waste power made gets turned into heat at the regulator.

Figure if sized correctly it should output the power needed. Can bolt the mag cup to the crank pulley and bracket to hold the stator. No belts needed.

Seing what your thoughts are.
Seems all the smaller engines in powersports still using stators. Either packaging or weight or both.
