Motor Temp

I have a Searfrost DC 5000 and just had issues with the motor. I had a new bearing put in and the brushes and stator (?) cleaned up.

Put it all back together and it seems to be running fine; but, the motor gets quite HOT! My little infared temp sensor just said it needs a new batter but the temps I was getting were at about 170 degrees F. I can't hold my hand on the motor without getting a burn!

I've looked all over the web and can't find what temp I should expect out of this!

Thanks in advance.

did you check the water pump. Looks like it is water cooled.

Yep, water cooled compressor but not the motor. And the water is flowing; the holding plates are dropping, the amp draw is dropping. Everything looks good but I never checked how hot it was running when new.

That does seem hot now that I look at it closer. Neat unit. I was thinking hermetically sealed.Maybe give sea frost a holler they are pretty good on support. Last though you check the electrical connections through out

Just had the motor rebuilt and upgraded the wire to 8 gauge. The cleaned it up and replaced a bearing. I email Leeson the motor maker and will email Seafrost for Monday. It is a neat unit and I want it to work well without all this heartache. This is the 3rd time I've been working on the motor.
