We are using the denso motor to direct drive a pincer.
Normally, there is little load on the motor, and the motor drives smoothly in both directions with about 3-4 Volts on a bench power supply. We have a bushing support on the end of the shaft to minimize cantilever loads.

However, if we run the motor into the hard stop (thus, applying a sizeable backdrive torque) the motor will not run in reverse. Even after unloading it, we need to run it up to 12V to get it unstuck.

Has anyone seen this kind of behavior with the densos?
We've never had this kind of problem before.
