I would like to find a switching power supply to power one ClearPath servo motor. I am aware that SMPS is not recommended for servos, but I don't need power for fast deceleration/acceleration. Beyond current/voltage requirements, I am a bit baffled as to how to find a reliable SMPS that can handle some regen power. Hopefully someone can provide some insights.

    \$\begingroup\$ Have you considered asking the manufacturer of that industrial servomotor for a recommendation? \$\endgroup\$ Commented Oct 6, 2020 at 19:28
  • \$\begingroup\$ You could always add a a power absorber circuit so that the SMPS doesn't have to handle the backflow of power itself. I don't know much about them, just that they exist. Could just be a cap with a breakdown device for all I know. \$\endgroup\$

  • \$\begingroup\$ @ChrisStratton In their FAQ Teknic advises against using any switching type power supply that is not specifically designed for servo motors. They told me a SMPS might work for my application but did not give any recommendation. \$\endgroup\$ Commented Oct 7, 2020 at 19:32
  • \$\begingroup\$ @DKNguyen Thanks for the suggestion! I found something like that:applied-motion.com/products/accessories/rc880:) \$\endgroup\$ Commented Oct 7, 2020 at 20:01
  • \$\begingroup\$ @YumekaMengjiaLYU Glad you found something. Sounds like (and priced as if) it is an active device rather than a passive clamp. I wonder what mechanism it is using to clamp. \$\endgroup\$

I came across your power supply comments. It looks like you may have already reached out directly to a Teknic Engineer and received some feedback in regard to your power supply question.

Needless to say sizing and choosing the correct power supply for an application is not a simple task and is actually much more involved then most realize.

Here is a link to a helpful technical article on how best to choose and size the right power supply for your application: https://www.teknic.com/selecting-power-supply/

Hopefully this helps make your decision a bit easier!

  • \$\begingroup\$ Welcome :-) Since the original question was about a product from the company you represent, you do disclose your link to the company, and the power supply-related link is relevant, I won't flag this as spam (something which we guard against here). Please be careful not to be seen as excessively promoting the company on unrelated topics. But the technical content here is effectively a "link only answer", and as explained in this topic on Meta.SE, an answer which just points elsewhere is "not an answer". Can you edit it to add more technical value? \$\endgroup\$
