Thanks again for all the comments. Let me respond.
Plasgears:
Unlike most automotive or large engine starters, the pinion teeth in this case stay in contact with the mating gear always. There is a clutch in the flywheel to prevent backdriving of the starter motor once the engine is running...
Ok, thanks for the replies so far. To answer the calls for more info: the motor is a starter motor on a motorcycle. This really isn't work related, but, being an engineer - I'm very curious about the tooth wear I'm seeing. Here's what I know:
The motor turns extremely slowly (judging by...
Hey all, I have what appears to be a motor problem that may actually be a gear problem. I have visually inspected the gear and the teeth are worn nearly half-way through the original thickness. Since the motor driving this gear struggles and draws a lot more current than it should, I'm...
Thanks again for all the suggestions:
The problem is VERY repeatable, and we haven't ruled out an electrical problem. Our servo/software guru has been "playing" with the drive tuning, but that doesn't seem to make much difference except in how much time it takes to settle down after a move...
Thanks for the prompt replies, I'll answer some of the resulting questions:
The encoder is using SSI interface and is currently giving us 32770 steps per revolution. Our motion control board uses a non-floating point processor, so we sometimes lose a few counts doing the math, but a few counts...
Hello all,
I've recently attempted to field an antenna rotator system and have been stalled by what appears to be a backlash problem. I currently have a closed-loop feedback in place using an optical encoder. The encoder is driven via a 60-tooth, 24 DP, anti-backlash gear mated with a...
