He had mentioned that the hp ratings were not equal in an early post. This is strong suggestion it's
consequent pole. Most dual winding motors tend to be equal hp rating on the two speeds. Never
seen one that wasn't. ....
Maybe that was a statement... seemed more like a question as in "that's how these work, right?".
In any case, we got the information, and it does seem like a regular Dahlander type, based on the information.
We recently had a thread on a motor that was two winding same power. They easily can be, or they could be different, it depends what is wanted by the application, as well as on the amount of oversizing of the motor, and the proportioning of the windings as far as slot space.
Whenever the motor is equal power, it necessarily will be a lower power than it could be in the same frame. If unequal, it can be closer to full normal power for the frame size, and there is a chance that the slower speed may not need as much power anyhow.
However, the Dahlander uses the slot space the most efficiently, as it always uses all the windings. As it makes for lower power on one, there is little reason to do that with two windings. The best reason to use dual unequal windings is to use a much cheaper and smaller switch, for speed switched machines in which the slow speed can tolerate less power.
That's what you get with a VFD after all. Less power at slower speeds.
