Haydon Kerk Motion Solutions offers a unique line of hybrid stepper motor linear actuators that open new avenues for equipment designers who require high performance and exceptional endurance in a very small package.  The various patent pending designs use a proprietary manufacturing process, which incorporates engineering thermoplastics in the rotor drive nut and a stainless steel acme lead screw.  This allows the linear actuator to be much quieter, more efficient and more durable than the v-thread and bronze nut configuration commonly used in other linear actuators.  Motor life is improved more than 10 times over the traditional bronze nut style – and it requires no maintenance and does not affect the cost.  An additional feature is the bearing pre-load adjustment which, unlike other designs, does not protrude from the motor configuration commonly used in other actuators.  

The Haydon™ brand of hybrid linear actuators come in six sizes, from 21 mm square to 87 mm square corresponding to NEMA size 8, size 11, size 14, size 17, size 23, and size 34.  Each size has three designs available – captive, non-captive and an external linear version.  There are over twenty different travels per step available, from .00006 inch (.001524 mm) to .005 inch (.127 mm).  Micro stepping can be used for even finer resolution.

These linear actuators are ideal for applications requiring a combination of precise positioning, rapid motion and long life.  Typical applications include X-Y tables, medical equipment, semiconductor handling, telecommunications equipment, valve control, and numerous other uses.

The Haydon™ brand of can-stack stepper motor linear actuators provides both a broader range and, for a given size, significantly higher thrust than previously available from mini-steppers. Five basic frame sizes are available, Ø 15 mm (.59"), Ø 20 mm (.79"), Ø 26 mm (1"), Ø 36 mm (1.4") and Ø 46 mm (1.8"). Available step increments vary with the motor frame sizes and are dependent on the basic step angle of the motor and the lead screw pitch. A captive, external or non-captive shaft (lead screw) option can be supplied for almost every size. The captive shaft configuration features a built-in "anti-rotation" design. The non-captive shaft option requires the customer to provide external anti-rotation. The external linear actuators incorporate a rotary lead screw and an external translating nut. These motors are ideal for applications where there is no space behind the motor for a through-screw design. Both unipolar and bipolar coil configurations are available.

Haydon Kerk Motion Solutions patented design accepts a larger rotor than conventional units, improving efficiency and eliminating the need for massive heat sinks. Unique features impart ruggedness and reliability that assure long life and consistent performance. Rare earth magnets are available for even higher thrust. All units are built with dual ball bearings for greater motion control, precise step accuracy and long life.

Applications include medical instrumentation, machinery automation, entertainment, semiconductor, robotics, sophisticated pumping systems and other automated devices which require precise remote controlled linear movement in a broad range of temperature environments
