How does the Wye winding improve output at idle?Really good output @ idle because of the Wye windings inside vs. the delta windings most of the others use.
I really don't know how but that's what the rep from Powermaster told me. At the time their 100 amp alternator could produce 70 amps @ idle (2400 alternator rpm) and the Summit equivalent could produce 20 amps but both could produce 100 amp at highway speeds (6000 alternator rpm).How does the Wye winding improve output at idle?
I've always favored Wye windings, but only because they can be tested with an ohmmeter; delta windings can't be.
Had no idea there was a difference in output related to the style of construction.
DC Power Inc, Mechman, and Ohio Generator are a few other popular names in the aftermarket high output alternator world. I have a smaller one from Ohio Generator on my red truck, it's taken quite a beating for the past decade plus and is still working great (knock on wood). None of these brands are cheap, but I believe they all have options for very high (think 150A+) output at idle. Probably overkill for most people, but if you're running a ton of lights/fans or a giant stereo they might be worth a look.
all 3 brands listed are fantastic. i'd add in singer (not stinger) alternators as well. i know multiple people with dc power alts with 100k+ miles on them. i myself have 2 singer 370a large case alts (and 1 CES 370a), which are rated for about 220a at idle.DC Power Inc, Mechman, and Ohio Generator are a few other popular names in the aftermarket high output alternator world.
