Dynamotor normal run temperature.
I managed to get a NIB BC-454-B for pretty cheap. I decided to keep it 100% original, so I put a Dynamotor on it and cobbled up a 28VDC supply. Works great as a WWV monitor. I've never run a dynamotor this long before. The question is: What is the proper running temperature for these small dynamotors? Seems quite hot. (Yes, I repacked the bearings). I have another dynamotor, not for the BC-454, that says "50C continuous operation" Is that how hot it gets or is that its expected ambient. TIA. Steve. -- Steven D.
