Advice on buying servos.

[m_c]

Do you know what the ratio was on the Triac servos?

I've only got the parts list for the stepper version, and it uses 12:30. Chaz has a servo version, but I don't think there would be much room to go for a higher ratio.

What size timing pulleys would you suggest for 200 or 400 watt servos? I was thinking that 5M 9mm wide belt should be about right. Centres should be around 100mm.

I'd say 15mm belt width minimum.

If you download the Gates DF software, it will generate suitable drive options.

I suggest you take the advice of the guy who didn't know what a harmonic drive was and couldn't be arsed to look it up before being clever about being wrong :D

I know what a harmonic drive gearbox is, i was just incorrect on the technical term used to describe them. I was selling them 15 years ago, but made by spinea.
