Vandalia, Oh. – Johnson Electric introduces the Saia Compact Driver, a fully integrated step driver/motor solution that reduces design and integration time, and improves device performance compared with traditional stepper solutions by virtue of reduced parts count and greater immunity to electromagnetic interference.   Where space and power is at a premium, the Compact Driver’s low power consumption and small footprint make it a particularly 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 stepper motors. The linear Compact Driver solution provides 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 an Saia UGA, UGD or UGM gearbox to obtain higher torque and RPM outputs, and increase step resolution, all from the same integrated driver board.

The Compact Driver’s algorithm is programmed to detect the end of the motor’s stroke. This automated end stop detection eliminates noise, reduces mechanical stress, and compensates for transverse distance tolerances, helping decrease system hysteresis and maximizing operating life.

Additionally, the Compact Driver is available with three different types of control interfaces that can be used for any number of applications where on/off or proportional functions are desired, making it simple to integrate into new and existing device designs. The ON/OFF mode is operated by an external switch where the proportional function is controlled by a 0-10V or pulse width modulation (PMW) signal.
