 There hasn't been an announcement to buy pool noodles yet. Considering that they are already out of stores in most of the country, draw whatever conclusion that you like. - Joe Ross [more] |

CIM Noise
So, we have two CIMs hooked up to an AM ToughBox. This is driving a pulley with a cable, lifting up a lift. Lots of torque, but not too much.
The first time you lift the lift, it goes up nice and smoothly. No motor noise. The second time you lift the lift, the motors start making a terrible vibrating sound, almost as if they are being stalled. Increasing the speed reduces the noise, and at full speed there is no noise (but we would NEVER want to lift our lift at full speed.) If you let it sit for about 10 minutes (I'm assuming the motor 'cools', or something to that effect), and try it again, on the first lift, there is no noise again. Any Thoughts? (I can provide torque values if required.) Jacob |
