Candy Dryer motor wiring.

[drbgc38]

Hi - I am just here to ask for help with my Candy tumble dryer motor, which I have extracted and wish to use in a project. The windings have three wires coming out: Orange, Blue, and Grey. The motor works with just the orange and blue connected to the mains supply (live and neutral), with the grey not connected to anything. It doesn't self-start, but it runs once I give it a spin.

The capacitor appears to be OK (still not sure) so it seems likely that the lack of self-starting is because of the grey wire not being connected to anything.

How should I connect the grey wire? Bearing in mind that the motor is to be used externally, not back in the original dryer.

Many thanks

You may not need to connect to all three wires. It could be that connecting to two of the wires makes the motor turn one way and connecting to a different pair makes it work the other way.

If the motor doesn't start, it's likely the capacitor. If it still runs when spun to start with the capacitor disconnected, the problem is definitely the capacitor or the connection to the capacitor.

OK, thank you. I haven't tested the capacitor properly yet, so that does remain a likely explanation.

Do you have any information on colour codes for wires on this motor, by any chance? The thing is that in the dryer, the grey wire did lead somewhere (to the base of the thermostat control), after turning white at the motor's junction box, so I am still not sure what its function might be.
