    Raising Power Factor of Induction Motor with PMDC Generator

    Thanks, electricpete and waross, for the responses. I think I'll try a balance between capacitive and resistive loads, instead of using a mechanical load. I may eventually look for something to "brake" the motor, but this still seems expensive and dangerous. To smallgeek, I am really just...

    Raising Power Factor of Induction Motor with PMDC Generator

    So, with the unloaded induction motor, I draw about 250W (208V @ 1.2A) and 1.22kVAR (power factor of 0.2). If I add 1.38kW load in parallel to the system, would I get a resultant of 1.63kw and 1.22kVAR (power factor of 0.8)? The current through my resistive load would also bring up the current...

    Raising Power Factor of Induction Motor with PMDC Generator

    Sorry for the double post, but I should correct myself. The reactive power is a concern, as it is governing the power factor. Will increasing a mechanical load on the induction motor lower the VAR, thus inceasing my power factor? Can I add enough Real Power to make the angle between real and...

    Raising Power Factor of Induction Motor with PMDC Generator

    Yes, electricpete, that is what I am trying to do. I understand reactive versus real power. Reactive power is not too much a concern, aside from the angle between my voltage and currnent. I need a load that can connect to three phase 208V out of the wall, that draws about 10 Amp (2.08 kW) and...

    Raising Power Factor of Induction Motor with PMDC Generator

    Yes, the purpose of this is just to have this particular load of ~10A @ 208V and a power factor of about 0.80. The only reason for using the induction motor is to add inductive power. I feel, even if I have a full load on the induction motor, my pf will still be low, which is why I would have...

    Raising Power Factor of Induction Motor with PMDC Generator

    Currently, with no-load, I am seeing a pf of about 0.22 and a current draw of about 1.2A. Putting any load on this motor would not cause the motor to increase pf? I would expect the load would be causing the machine to increase the current and inductive power.

    Raising Power Factor of Induction Motor with PMDC Generator

    Here's what I'm doing: I am building a test bench that will require 5 - 20 with a power factor of 0.80 ~ 0.95. I have a 208V tree-phase supply from the wall. Here's what I'm planning: I already have a 1725 RPM, 1/4 HP, 208V three-phase, 60Hz, Induction motor. I want to couple the induction...
