I believe the RM24 uses 9 poles, as opposed to 6 for the single-phase stators.
It would be interesting to build a test rig, similar to the one used to test Zener diodes, to compare current and voltage output at different RPM.
My only comparison came when I installed an RM24 on my A65. The voltage measured at the battery
goes to 14V at a little over 2000RPM. I no longer need to ride five miles after a short trip to the store just to recharge the battery
