Hello All!!!

I recently purchased a hurco KM3P. After some issues I have had (and others I have read about) I have decided to retrofit this machine. One of the many open issues is my servo motors. The books I got with the machine says that the servos are DC PM servos with a tac and encoder. The end of the encoder covers say EC. My assumption is that they are electro-craft??? All the tags on the motors are barely readable but I did get this model number off of one of them 727-902-0768-4. The encoder part number is 0020-0736 Model number is S-9992B made by ledex in ohio.

Does anyone know anything about these?

are there any drives I can use with these motors? Maybe viper200?

If not, I have some Galil servos that are 80VDC PM. The part number is N34-150-1000. Below I have attached a PDF with the specs for these motors. (Al_the_man has seen this before )My concern is I don't know if they are strong enough to uses them to move my knee mill around. (Not meaning I'm going to use a motor on the knee for Z axis.) I could gear them with a gearhead or timing belt??? Most likely I would have to do that to slow the rapid down anyhow. Any suggestions on if these will do the job or can someone lead me in the right direction on how to figure out if they would have enough power??

Any suggestions or help anyone could offer would be greatly appreciated!!

Thanks
Allen

Hello again

After looking through some of my documentation I found the following part number for the servos. It states that it is a EC servo part number 401-4003-015. Maybe this will help.

Thanks Again
