Furnace Motor on Generator, Reduced Voltage?

Question

I am currently running my furnace on a generator because of what is expected to be a PROLONGED power outage here in the Howling Godless Wilderness of Illinois. My generator is 1500W Run 1850W Surge, so I am cycling the furnace manually so that it is the only load on the generator when running. The Voltage at the Motor is 99 Volts, and the motor starts rather slowly and is running a BIT slower than off the mains, So, IS IT DAMAGING TO RUN a 1/3 Horsepower Split Phase Motor designed for 115V on 99V ??

I hava a NATURAL GAS Furnace, so the only load is the Blower Motor

Answer 1

It's unfortunate you couldn't have known about the problem before the power outage. Have you operated the furnace from generator before this outage?

What is the output voltage of the generator under no load? This would help determine if the generator may have a fault from the start.

I would be reluctant to operate the furnace under the conditions you describe. Under low voltage and low speed the motor may require higher than normal current and may overheat.

Read through my generator page for other generator operating and safety concerns.

They shrink the impedance to severe frequency alerts via effectively shorting them to floor. you're able to desire to do an identical with a bite of twine. yet on condition that capacitors have a severe impedance to DC, they are able to enable a DC voltage to be cutting-edge whilst shorting the severe-frequency stuff to floor. And as you're able to convey mutually from this, capacitors do not do a brilliant activity of lowering low-frequency noise. As you're able to already know, the impedance of a capacitor to an AC sign is a million/(2PI*frequency*capacitance). So the better the frequency, the decrease the impedance of the capacitor and the heavier of load it is going to represent. and since the voltage regulator does not have a limiteless force skill, fantastically at severe frequency, the severe frequency alerts generate via the regulator(or via the burden) get decreased or attenuated. And as pronounced above, a capactitor can respond to ameliorations in cutting-edge call for quicker than the regulator can. If the capacitor isn't there, the output voltage of the regulator can dip extremely critically whilst the regulator circuit is taking it's time to answer the present call for.

no ,no problem only you will get lower output power,remeber you are using furnace which is respected as resisitive laod,which will take all power of your generator.how many watts your furnace consume?
