have question about the typical 115v motors, probably anything 1hp or less, that are in forced hot air hvac systems and having multiple speeds.
Just had mine replaced. The original and new motor are AOSmith. Original was straight forward- Black/Blue/Red motor leads are for high/med/lo speeds respectively, and connect to same color incoming wires. It is capacitive start, so the common line of the motor (white) comes out the motor case on the other side away from the black/blue/red leads, with the brown wire which goes to the capacitor. In this scenario, the white common line of the motor goes to common side of the capacitor, and it connects there with the incoming common wire.
On the new motor, it has a white/common lead coming out the motor case with the black/blue/red leads. And for the capacitor wire(s), they come out the case on the other side and there are 2, one brown and the other brown with white stripe.
Question I have with this setup, is the white lead the same as the brown/white striped lead? Or is the brown/white a common line on a separate winding within the motor?
What if I don't connect the solid white lead and tape it off, and connect just the brown/white lead to common side of capacitor along with the incoming white wire?
What if solid white motor lead connects to incoming white wire, and brown/white stripe wire goes to capacitor common and brown wire goes to other capacitor post? This is how the tag on the motor illustrates hookup. Is the brown/white extra wire just for simplifying hookup to a capacitor, one wire only to a component?
I guess another question I should ask, is this a capacitive start only type motor, by this I mean once running the capacitor no longer functions in the circuit? Paper that came with motor didn't go that far into detail, and I see articles here and there about continuous capacitor type motors
