This comes by virtue of reduced parts count and greater immunity to
electromagnetic interference, says the vendor. Where space and power is
at a premium, the Compact Driver’s low power consumption and small
footprint make it an attractive motion solution for battery-powered
portable devices. The Compact Driver provides 3-wire operation of 28mm
Saia motors, including UCL and UCE linear step motors, and UCD and UCB
rotary step motors. The linear Compact Driver solution can provide
forces from 0.1 to 50N with a step resolution down to 0.021mm and
distances up to 150mm. The rotary Compact Driver solution can be
combined with a Saia UGA, UGD or UGM gearbox to obtain higher torque and
RPM outputs, and increase step resolution, all from the same integrated
driver board.Johnson Electricwww.saia-motor-usa.com937.454.2345
