HSI has introduced a size 14 linear/rotary dual motion unit to its hybrid stepper motor product line. The linear/rotary unit provides linear and rotary motion in one compact package. The patent-pending design provides incremental rotational and linear movement of the output shaft. The two degrees of freedom in movement can be actuated independently or concurrently. These devices can be run using a standard two-axis stepper motor driver. Performance can be enhanced using chopper and/or micro stepping drives. HIS states that no maintenance is required and that the entire actuator is designed for long service life. The linear/ rotary unit allows for simplified system design and a reduction in the number of components. It is suited to tight fitting applications requiring precise two degree of freedom, controllable motion, pick and place equipment, robotics, and a wide array of instrumentation.
