MiniMikro Designs for Elliptecmotors
The intention of our MiniMikro designs are to analyze
the possibilities of using the elliptecmotor for low cost applications and
to offer some small pcb's or ready designs for your different rotary and linear
solutions and ideas. It is not the intention to perform micrometer
positioning accuracy but at least a good performance for moving
backward and forward and for stepping the elliptecmotor.
The MiniMikro designs support the Atmel ISP/SPI
Programming interface.This will allow you to flash (upload/download) your
own 8051 assembler software. The programmable I/O lines are for easy
signal implementation e.g. you might want to program various
external start / stop / forward / backward / stepping switches or external
sensors for your environment as you need it to control your mechanics.
The feedback of the Elliptecmotor current is not measured with
an integrated and cost effective A/D converter. The MiniMikro designs
use our low cost idea to get the feedback of the elliptecmotor for forward
and backward operation frequencies and might also be
helpfull to adapt the elliptecmotor to other existing,
single cycle 8051 microcontroller designs.
You can find more details about the
microcontroller in the Atmel specifications: (Atmel specs ).
Here you can find
more details about the elliptec motor: (Elliptec
Resonant Actuators ).
