Is that sound a result of mechanical rotation or air compression?

[Marshall7302]

@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.

Do you know is this motor started by a wye-delta contactor set up. It has a unique whine in both stages.

At one time the wye-delta was used as a poor mans soft start for high inertia or hard starting loads, but as technology has advanced, so has the modern day 3 phase soft start controls. There seems to be a lot of pros and cons of both methods, but it ultimately depends on the application.

Its nice to see some old school equipment still in use.

@puttz1976 i will get back to you on this.

@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.
