Re: Stepper motors in sound sensitive enviorment

Your link is rotary encoder

I know linear encoder as in
[en.wikipedia.org]

I still don't understand why SIX motors?

I still don't understand what maximum movements are necessary?

What type of drive? Belt, line, leadscrew?

I don't understand the need for encoder? Stepper motor with 3200 steps per rotation
can do repeatable positioning with great accuracy without encoder feedback.

You will have six RS232, RS485, USB interfaces to drive motors
six more RS232, RS485, USB interfaces for encoder feedback

$250 per driver
$72 per encoder

Insanity!!! You could get 12 smoothieboard controllers or 10 Rambo controllers
each could control 5 stepper motors and have a fast processor to do all the firmware duties.
and one USB or ethernet interface to worry about.

Simplicity is NOT a requirement?
This "Calibration device" sounds more like robot that will roam around looking for sounds?

Good luck!

Thanks for replying.

I'm using a linear encoder Link.
These encoders working conjunction with this controller Link.

This is a digital encoder. It can be controlled via either RS232 or RS485. The end goal is to connect six of these to the RS485 bus.
The master of these motors will be a piece of custom software on a PC. The software will be written in c++, and in the end offer high level controls to control the robot. This software will be made into a library, and then ported to matlab so the thing can be controlled from matlab code.

This thing wont have a stage. Like I said, these motors will surely be powerful enough. Another engineer made a design and did the calculations. The motors must be able to reach a step angle of at least 0.5 degrees, which I can manage through the use of gearing.
