What is the difference in MTR-0002

What is the difference in the GM4050 and the GM4050F-1 ?

Tags look the same. I have one of each.

F1 may be for the rotary table or indexer. If you can provide a picture of each label I may be able to help more.

FAST--
The difference is the 4050fs-1 is for an A or B rotary axis.

tag is the same as the gm4050 I have on my X today. I purchased it as a X axis replacement. The tags are the same except the GM4050 and GM4050F-1 ..I was told it was the Y axis on a 4020 is what it came from.

To follow up on my question with my understanding I have now.

4050F is the same as plain 4050.

4050 is the stack length and diameter.
F is for Fadal
FS is for Fadal Short and these were used with the rotary heads.

thank you for info David

I worked directly with Glentek with its development, we used FS to signify "Fadal Short". We needed to have a 4050 motor as short as possible for the A-axis so it didn't push out the door with a full Y+ move. The feed back end of the motor was made as short as possible.

The "40" is the diameter and 50 is the stack length of the magnets/windings. So the 4020 motor has the same diameter as the 4050 motor but a shorter stack length. The "F" designation was added to the original 4050 motor when the "FS" was first introduced. The MTR-0003 was introduced with a crimp-tight connector in order to help seal the motor... david@vmcelectric.com

Haha, You mean real people actually made these machines. Someday someone will sit in awe as I tell them the horror of how concert pianos were made. Thanks for the info.
