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 ).

A picture of our working prototype (Jan. 2006)
The additional PCB with the switches (as user interface) was mounted direct onto the ISP Pinhead and controls calibration, moving / stepping forward and backward.
