Anybody know what the impedance reading suppose to be between a winding of a single phase motor?

Question

I know the reading between a winding on a 3 phase motor is about 2 ohms. I'm just curious about a single phase motor.

Answer 1

Impeadance would be 115 / 7.1 = 16.2 ohms

Answer 2

Depends entirely upon the motor. What HP rating? Full load amps?

I have a 3 ph. we are installing at work right now, DC impedance is about 7 ohms. 300 HP. Also I think you mean across a winding.

Edit: Measuring motors can be a little tricky. When you use a meter you are measuring DC impedance(resistance) In operation it will generally be higher (AC will almost always be higher) No' larger does not mean higher impedance. Actually is generally lower  for a given voltage. Because to get more power you would need more current in order to achieve a higher magnetic flux. I know this is as clear as the face shield on my motorcycle helmet.  Related to your question but not asked is start up current draw which is often much higher than run current.

In a motor, you can reduce impedance to get higher current  which would indicate falsely that less wire produces more power even though lower impedenc allows greater current, therefore highr magnetic flux. But with more windings with less currentthe total effective magnetic field  may be higher. Now that I  

have spouted theory that you did not ask for, the other guy gave a goodaproximation.
