21000 SERIES SIZE 8 STEPPER MOTOR LINEAR ACTUATOR

Equipment designers and engineers now have an even more compact option for their motion applications. The Haydon 21000 Series Size 8 stepper motor based linear actuator occupies a minimal 0.8” (21 mm) space and includes numerous patent pending innovations that provide customers high performance and endurance in a very small package. Three designs are available, captive, non-captive and external linear versions. The 21000 Series is available in a wide variety of resolutions — from 0.00006” (.0015 mm) per step to 0.00157” (0.04 mm) per step. The Size 8 stepper motor based linear actuator delivers thrust of up to 10 lbs (4.5 Kg).

PERFORMANCE CURVES - 21000 SERIES - FORCE VS. PULSE RATE STEPPER MOTOR LINEAR ACTUATOR

Size 8 Stepper Motor Linear Actuator Force Curves

*Care should be taken when utilizing these screw pitches to ensure that the physical load limits of the motor are not exceeded. Please consult the factory for advice in selecting the proper pitch for your application.

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.

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

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.
