text: <s>[INST] Suggestion for a servo motor required to connect to rockwell servo Summary: Selection of a suitable servo motorHi, I want to connect a suitable Rockwell servo motor to a Rockwell drive system. The PLC used by my customer is AB PLC L36ERM. I want to connect a suitable Rockwell servo motor to this. The torque requirements are very less. The mechanicals comprise of a linear timing belt and carriage. At present we use a stepper motor with a max holding torque of 101 Ncm. Anything more than this would also be suitable. Could anyone suggest which motor would be suitable? thanks arun [/INST] You've given very few facts with which to size a servo system. You've only given us a processor model, so you could use a K350 or a K5500 economically. But you've not said anything about voltage so no one could recommend more than that. You've given only torque, you've said nothing about the necessary speed. You've told us the type of mechanical setup, but nothing at all about reduction ratios, load, inertia, friction, cycle time, etc. You need to give us a LOT more information if you want useful recommendations from us. I suggest you use Rockwell's Motion Analyzer: https://motionanalyzer.rockwellautomation.com/ \\n </s>
