FWIW another way to destroy CIMs (or at least Mini-CIMs, but all the same) is to run a flywheel directly off the output shaft with no extra support. This does something weird to the contactors, so that the motor only starts from certain angles, and when it does, it's pretty weak.


Remember kids: motors are not load-supporting bearings.

Friends don't let friends smell smoked BAGs.
Can confirm - we smoked a BAG this year on our swerve. I can't describe the smell other than it was terribly potent. The versaplanetary it ran into also smells awful now too.

The CIM family of motors create the worst stench when you smoke them.

I remember on Windham in 2015 we smoked two miniCIMs when our programmers were tuning the elevator. They thought they disabled the robot and 10 minutes later the foulest smell filled the shop as the robot kept trying to hold position with a full stack of totes & can.

I've yet to smell something worse or one that lingers long after.
