Servo inquiry

[axle22]

Anyone here who has worked on or used SM60 SERIES on any project?

If not, at least a servo which share the same specs with the SM60 Series.

Here are its specifications:

Voltage: 220V
No.s of Poles: 8
No.s of encoder lines: 2500 PPR
Rated Speed: 3000 RPM
Rated torque: 0.637-1.91 N.M
Work temperature: -10-55℃
Insulation Class: H

Looking forward to your insights!

Easily controlled by any PIC, easier if using a USDigital encoder interface chip. The 'spec sheet' leaves a lot to be desired though.

Important to understand, this is just the motor/encoder. It is not a 'servo'.

It becomes a servo, when suitably driven. If you look at the page, it just says 'SM60 Motor'.
It becomes a servo system, when attached to a suitable driver, with suitable software. This can easily be a PIC, but it is not a small project.

Now a lot depends on how many you want to use?.
It is definitely _not_ worthwhile looking at developing a controller for this for a 'one off', or even a few. Better to buy an off the shelf motor control board. It is the sort of project that becomes economic, if you are likely to drive many dozens of units. There are code examples to use a PIC as an AC controller around, but these would be the smallest part of the project. The hardware to develop 220v AC feeds would be a lot of work.

A typical servo driver board for this, would be something like:

You will see these offer serial, voltage and pulse control inputs that can be fed from a PIC or PC etc..
