All phased out!

Alternator is single phase, you identify alternators by looking inside the stator and counting number of poles, 6 for single, 9 for triple, when I fitted a combined rectifier/regulator I got one rated for 180w.

Great, thank you. Off to buy the right rectifier now!

Hi there,

Totally confused about the single/triple phase business! I have a Mk3 ES commando and want to put a solid state rectifier in togeher with a Pazon ignition system. A few questions really, firstly is the standard Mk3 ES Commando fitted with a single phase alternator? Secondlycan you tellvisually? And finally, if it is single phase does the Mk3 need a higher rated rectifier if it is putting out 180 watts vs 120 watts in earlier bikes?

Any feedback much appreciated.

Al Oz adds a few words. three or single Phase is 9 or 6 poles as mentioned here. But the rotors are all the same ie 6 magnets, they are all identicaly magnetically/electrically. They are not 'selected' as was mentined on here once. The worry about 180Watts out put or even 200W is a bit academic as these figures are quoted at 7 Thousand revs. Most regualtor/rectifiers we buy these days are up to the job. Even the humble rectifier, now being replaced by the encapsulated square block is usualy well capable of handling the power.

Hi Al, thank you for the reply and apologies for not acknowledging it sooner. I did wonder if the alternator would ever be asked to spin that fast, but I got a higher rated rectifier just to be on the safe side - it wasn't much more anyway. All wired in and just waiting for a few more bits..................
