@GliTCH11 it is rotation of 3 different stages in side blower housing just infront of the motor. your actually looking at the back of the motor the spinning shaft you see used to connect to a electrical generator for the organ low voltage supply.
@puttz1976 But this motor does not need a "soft start" circuit. All spencers left the factory designed to start on full voltage. Besides, the blower makes a much better and louder startup sound when started up with full voltage and no soft-start circuit. Should of left it stock as originally engineered. That soft-start just complicates things, costs more money, and messes up the cool wind up sound of the blower.

It's possible the soft-start was added to reduce inrush current, which is perfectly valid if there are external factors affecting the supply.
Is that sound a result of mechanical rotation or air compression?
@puttz1976 i will get back to you on this.
