I read that someone had designed a motor part for the reprap, i failed to find these designs.
I have an idea that might work, an ultrasonic motor, consists of a pcb
with an etched / or milled out stator winding, and ceramic capasitors
soldered to the stator. moding the rep to a pick/place machine that solders the caps might work building these ,and a dremel like tool could mill out the stator design
it would also need a sin/cos osclillator about 40 khz and a transformer to boost the voltage to about 200 volts. i doubt it would be very powerful and also probably complex to build (10 mm stator would need 32 capacitors, 16 pr side)
it would work just one side but with less torque
any better designs out there ? (looking for high torque simple motors about 10 mm
for robotic fingers) 2 ultrasonic stators with 3 levers between them sandwiched should give me 6 times the torque and maybe gearing it 1:10 60 times. that might be enuff force for my needs.
anyone had any luck soldering with lasers ?, maybe a small soldering iron is better ? and just feed solder from a reel as needed, should be easyer to control
the flow of solder this way.
also the capasitors are really small, maybe 1 mm long, any ideas on a pick tool
that would put them in the exact right place to get them soldered.
