I'm doing some software that will measure speed of rotation
and direction (quadrature). Early hardware not selected,
and of course not available yet. So does anyone know where
I can find an inexpensive d.c. motor that has a tacho with
signals for speed and quadrature? I've looked at Radio
Shack, Edmund's, and two robotic web sites so far. Spec's:
Speed: Don't care
Torque: Don't care
Size: Don't care
Shaft size: Don't care as long as it will easily connect to
tacho
Voltage: 0 to 5 if possible
Current: Low current so can run on D cells
Cost: Very low since this is a throw-away part.
I can't think of anything else to specify. The motor will
be driven using PWM most likely, but a buffered DAC can also
be used.
Thanks for any help.
