The print I have says that it is a 15A breaker 6-8seconds.

In the past when we used the window motors to lock a gripper, we put a switch at the end of the travel to shut the motor off rather than stall it.

FYI, the keyang motors have a PTC also.

We actually do stop the motor by detecting the stall by measuring the current increase. It works well, but in our debug session, we saw the motor "die a slow death" until it cooled.

I suspected the PTC, and you now confirm it.

Thanks,
