Your generator is just too small. An electric motor will pull many times it's full load ams on start up.

Thank you. A $16. Pulley fixed it.

The motor is rated at 3100 watts . The initial test that resulted in 38amp draw was performed with a 5k watt generator. Did you watch the entire video?

@@ffsdirtbike Correct. That is full load amps. The starting (locked rotor) current can be be or 6 times that amount when first starting. A clamp on amp meter will likely not catch that initial current load because it happens so fast. That initial amp draw is what pulls the generator down so hard. When powering from commercial power there are near unlimited amps available so that initial amp draw is unimportant. You would be must better off running your air compressor off an 8 - 10 kw generator. Although you are now able to start it with the smaller pulley, it is still hard on the motor and generator over the course of time.

In the video you can see ,with the original pulley, when I flip the switch on - with an amp clamp on one leg it shows a spike of 42 amps . This would indicate a starting draw of 10,080 watts. “ confirming what you are saying “ After downsizing the pulley, the initial start shows 19amps per leg or 4560 watts. And at full pressure it draws 11.5A per leg=2750watt just before cycling off . That is with in range of my generator. I appreciate your comment and comments like yours because they make me go back and double check my work. Many times I work off of intuition and in this case the sound I know the generator and compressor should make . Now that I have actually gone over the numbers, I know my generator is fine and will do the job , and my compressor will last many years. I can hear it when it starts. It’s making the correct noises. It’s not struggling. This is based on decades of working in shops next to compressors. I do plan on upgrading the power in my garage and adding a proper 240 V. Shore power outlet. I hope you keep watching my videos and keep commenting and keeping me honest . Thank you, sir.
