Humidifier Motor (Squirrel cage) Wiring

Hello,

The motor of my desktop humidifier was burnt. Since the part was not available, it was given for re-winding. I couldn't get the proper connection details from the guy who re-wound it.

Can anyone please help me to identify the line and neutral for the motor from the attached photo ?
The humidifier had 2 speed.

Welcome to the forums.

As a "guess" .... gray is neutral, red is low and black is high.

The only way to know for sure is with an ohmmeter, where the resistances of the windings are measured.

Thanx PJmax...

Line is usually used for speed control, right?
Is there any harm if the polarity is reversed?

Thanks,
Ran

The "line" is the combination of a hot and a neutral.

Your motor has two windings.... one for low speed and one for high speed. They share a common neutral wire. Since this A/C..... there is no polarity.
