28000 SERIES SIZE 11 STEPPER MOTOR LINEAR ACTUATOR

The Haydon™ Size 11 hybrid stepper motor linear actuators are one of our more compact additions to an extensive line of production proven miniature stepper motors. The various patent pending designs deliver high performance, opening avenues for equipment designers who require performance and endurance in a very small package. Three designs are available, captive, non-captive and external linear versions. The 28000 Series stepper motor based linear actuator is available in a wide variety of resolutions — from 0.000125” (.003175 mm) per step to 0.002” (.0508 mm) per step. The Size 11 stepper motor based linear actuator delivers thrust of up to 25 lbs (11.5 Kg).

Ramping can increase the performance of a motor either by increasing the top speed or getting a heavier load accelerated up to speed faster. Also, deceleration can be used to stop the motor without overshoot.

NOTE: All chopper drive curves were created with a 5 volt motor and a 40 volt power supply.

With L/R drives, peak force and speeds are reduced, using a unipolar drive will yield a further 30% force reduction.
