How warm should a Telechron motor assembly get?

I have a clock radio with a telechron motor that I noticed was kind of warm. At first I thought it was the transformer, but I have now determined that it is the coil for the telechron motor giving off the heat. I have read online that the coil should get warm but not too hot to touch. I measured the temperature with a thermometer and it is 130 degrees F. I thought maybe this coil was bad, but I have tested 3 other telechron clocks I have and got the same temperature results. I am wondering if anyone here knows exactly how warm these motor assemblies should get.

Update: I am testing my 6th clock. I'm guessing this is normal?

Not too sure tbh, I know they can get a bit hot, but I never measured it. It might help if they get some new lubrication on the inside but they are really hard to open up (in such a way that you can still use them).
