Motors Overheating?

I have 3 motors working a cascade lift. They overheat after 1 minute 10 seconds. Only one motor brakes to hold the lift and only one is actually running on full power. Any tips?

The fact that only one is braking and they are running at different power seem to be the issue.

You should be using every motor that is connected to that subsystem for every action you take. You are destroying the motors by running them at different speeds.

One seems to be locking up. Does this mean it’s burnt out? It runs for a while and then stops. It’ll click a little but won’t turn.
