I used to do tests with motors running constantly for several days with current levels less than 10 amps, which requires an external cooling fan. I always used the touch test to check if a motor was too hot. If you can't hold your finger on the motor for at least a few seconds then it's probably hotter than 60deg C...which is most likely not good. I'm really not sure what temperature the winding insulation starts to melt...I wasn't about to have a fire in the lab.

Looking at the illustration on Rockauto, my motors look the same as what's pictured for the Dorman unit. I'm not sure who makes the motors for their assemblies (or if they're even in-house), but it looks like I might be safe from ending up with a Chinese unit.

BTW, you know how one might be able to get replacement motors direct from Bosch (or at least any retailer that sells just the Bosch motors)?
