Temperature of Stepper motors

[ranchak]

What is the working temperature of an original BP Superior stepper motor? I have a problem with repeatability and I have tried about everything to find and duplicate this problem. I have finally slowed my IPM down to 20 IPM to see if I can get a part within tolerance. I did notice that my y motor is usually running hotter than the x. The x motor is at 106 degrees and the y motor will be at 124 degrees. Sometimes they both will get up to 134 degrees. I don't know what temp the motors where running at when I had the IPM up to 40 IPM.

We need to know what you are using for a driver and/or what the current is. Also, where are you taking the temperature?
Is this a Boss system?

The temperatures you state would be of no concern to me if they are in Fahrenheit but would be if they are centigrade.

Check the current going to the motors in a static state (8.0 amps) and in a running state. At rapid it should drop to about 2 to 2.5 amps. Temp of these motors has never been an issue. The aluminum heat sinks are massive.
Also note that The x axis accels and decels the mass of the table. The Y axis motor moves the mass of the table and saddle thus makes more heat.
