I've seen 1/4 hp shaded pole blower motors on a furnace, which should only use about 200 watts, less than 2 amps, draw 8-10 amps. The reason, the shaded pole motor isn't powerfactored. In theory if it were powerfactored, it should draw close to 2 amps, right?
Our residental electric meter can only sees the 2 amps, even if motor isn't PF. Am I right again?
A shaded pole fan motor generates a lot of heat. In theory, the heat produced is calculated by I squared R. So, is the heat produced inside a shaded pole motor based on the 10 amps or the 2 amps? If it's the 10 amps and our energy meter only sees 2 amps, are we getting more heat energy than we are paying for?
JohnT, Yes, this question goes to show you I have too much time on my hands.
