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. These high-performance hybrid actuators directly drive a rotor drive nut on a stainless steel precision acme lead screw. This patented interface reduces tolerances and noise while increasing efficiency and durability over v-thread and bronze nut configuration commonly used in other linear actuators. Actuators are available in captive, non-captive and external linear configurations.
Linear stepper motors are available with hybrid and permanent magnet motors. The linear stepper motor is based on a stepper motor to which a linear actuator is connected. There is a combined stepper motor and threaded rod where the motor moves the threaded rod back and forth. Hybrid linear stepper motors come in six sizes, the smallest being 21 x 21 mm and the largest 87 x 87 mm.
There are three different models for each size: captive, non-captive and external linear configuration. The motors have more than 20 different step lengths from 0.001524 to 0.127 mm. Micro-walking achieves even lower readings. The benefits of linear stepper motors are best seen in applications that require precise positioning, fast movement, and long service life.
The following list presents standard models, customer-specific models available for projects.
