AC servo motor for CNC mill spindle: Questions and answers

What's worked and what's not about using an AC servo motor (DMM Tech DYN4) on a LinuxCNC CNC retrofitted Precision Matthews PM-25MV milling machine. Many of these questions came from viewers and I hope this summary video will help the next person. I've tried to be very factual but mistakes are likely about the cause for problems that I didn't fully solve. Next video will describe the LinuxCNC DYN4 serial interface.

Table of contents 00:00 Introduction 00:32 What are the advantages of the stock BLDC motor? 00:44 Why upgrade the BLDC motor? 01:22 Why not just replace the original drive? 01:40 Why a servo motor? Why not a VFD driven induction motor? 02:20 Why not a servo motor? 03:03 What’s the simplest way to interface the servo motor? 04:24 Is there a more featureful way to interface the servo motor? 06:05 How about torque control mode? 06:28 Why not use the stock v-belt? Aren’t timing belts noisy? 08:03 Why use the motor’s encoder? Isn’t a spindle mounted encoder better? 11:21 Could I have made a more complicated setup? 13:12 Why not use a larger power servo than the original 750W BLDC? 15:02 Why select a servo with a brake? Doesn’t the brake harm performance? 16:09 Is there electrical noise from the servo drive? 18:20 Should the high-voltage electronics be installed into their own enclosure? 19:06 Could the DYN4 serial interface be used? 20:05 Has surface finish improved? 22:59 Are the electronics for a CNC retrofit expensive? 23:39 Does the motor run hot? 24:37 Why has this video taken so long to complete? 25:19 Are the LinuxCNC configuration files available? 25:29 Would I do this all again? 26:10 Thank you #KvvCreates, #LinuxCNC, #CNC
