87000 SERIES SIZE 34 STEPPER MOTOR LINEAR ACTUATORS

87000 Series, Size 34... our largest, most powerful stepper motor linear actuator is also available with a captive, non-captive, and external linear shaft. Despite its large size and strength, this stepper motor linear actuator incorporates the same precision, high performance and durable patented designs featured in our entire hybrid product line. The 87000 series delivers forces up to 500 lbs. (2224 N) in a compact, 3.4-in (87 mm) square package. The 87000 Series stepper motor linear actuators are available in a wide variety of resolutions - from 0.0005-in (.0127 mm) per step to 0.005-in (.127 mm) per step. Speeds exceed 3.0-in (7.62 cm) per second.

In addition to our standard configurations, Haydon Kerk Motion Solutions™ can custom build this powerful motor to meet your specific motion requirements. The in-house design and engineering team is available to assist you with a solution to fit your needs and your budget.

Standard Lubrication Options - Grease, No Grease, TFE Coating

 Size 34 Stepper Motor Linear Actuator Force Curves

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 75 volt power supply.

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