I'm wondering if this is true. A co-worker ( Heating and Ac trade) told me the other day that a 240 volts motor has more poles than a 120 volts one. So, it would rotate slower than the 120 volts. one. I know that speed is a inversely proportional to the number of poles in the stator.More poles ,slower thew RPM. But, Is that true? a 240 volts motor really has more ( He said " twice as much ') poles than the 120 volts one.? Where in the name tag of a motor can I read the number of poles a motor has?
We were troubleshooting a blower in a furnace which was not moving enough air. Come on! I also know that we always play by the 10% rule. You know + or - 10%. He said that an enexperinece tech. installed a 240 volts blower motor instead of a 120 volts one. By the way, this motor was installed in 2006 , how come it lasted so long?
I'm very new in this field. He's all the years of expeirence in this. Was him pulling my leag?
Please could you educate me on this subject or point me to a web site that I can read about it.
Thanks Rookie
