I've a rather shabby 2.2KW generator powered by a 5.5bhp knock off Honda, at least it's about that size, any labels have long since gone. I used it to power a 115mm grinder, a oldish Bosch that's never given me any trouble. A short while into the job the brushes in the grinder broke up and damaged the rotor wiring enough to stop it working. At the time I put it down to the age of the grinder etc.
I tried again recently with a newer similar sized Makita, again it's never given any trouble, and a similar thing happened to the brushes. This time not as badly and grinder still works.
Is there something about the way these generators produce power, a roughness of the sine wave or an inconsistent voltage maybe, that's makes these failures the fault of the generator? I'm reluctant to sacrifice another tool to it to confirm it. Once is happenstance, twice is coincidence, and thrice is enemy action: Al Capone, or Frankie Howerd.
