That suds pump.

If one is savvy enough, the Star point can be brought out, the ends split, the motor then rewired for Delta....
hermetic:
Quite right John, they can, but it usually means cutting into the binding, and then seperating the ends, adding some tails,insulating and rebinding. Not really a job for the faint hearted, though as you say, it can be done.

Phil,
Trouble is we ( savvy ones like you and me ) know this sort of thing and tend to take these things in our stride whereas the Joe in the street wouldn't know any better....so it's only thru forums like this that the knowledge can be put to use....words like 'wound' tend to infer exactly that...and it is taken that the motor is a Delta or Star wound motor rather than how the windings are or can be configured.....
Hats off to John, DB for showing how to mod a coolant pump motor to run single phase ....... :bow:

There are some motors where all the coil ends are not brought into the connector block, these function in either star or delta, but cannot be changed over from one to the other.

That's true 'star wound' or 'delta wound' are terms that are commonly used. Just as you might say 'doing the hoovering', even though you might not actually be using a Hoover.

Hi John, Yes I agree, doubleboosts video does a great service in showing how to reconnect a motor. but I fight a bit shy of telling anyone to dive into the binding and start soldering. the chances of damaging the insulating varnish are quite high if you havent done it before(or been trained to do it), and it might wreck an otherwise good motor which could be put to another purpose. Then there is the safety aspect. I would quite happily do it myself, or show someone how to do it, but from the safety point of view, I think it is best to find another motor!
