Micro linear servo actuator, mightyZAP has been developped for precise linear position control in small space.
The key feature of mightyZAP is a miniaturazation which integrates motor, gear box, circuitry and other linear mechanical parts in single small case. We realized miniaturation with durable lifespan, robust force (max. 100N) comparing to its size, and reliable repeatability (within 50μm). Force & speed are varied according to gear ratio for a model and that is, the stronger force, the slower speed.
Premium lineup mightyZAP is for industrial applications such as factory automation, medical equipment or UAV industry. Due to high performance coreless DC motor, premium lineup boasts stronger force and longer lifespan than economical lineup.


Control mightyZAP along with various API/library such as Arduino, C++, C#, JAVA and Python.


The large sized linear servo motors with AC power have been used widely in various industrial applications in modern industry. But in case of compact linear servo motors with DC power, it could not be applied to real applications yet due to limited force, speed, accuracy and durability while there have been considerable demands from the market.
Based on longstanding R&D, we proudly introduce our own compact linear servo motors which innovatively strengthened weak points of existing products in the market. From economical DX series to the premium LX series with coreless motor, we offer customized solutions of compact linear servo motors for various market demands.

Standard Accessories

Hinge : Hinge is rotatable by 90degree according to the mounting condition.
Without hinge, actuator can be mounted using IR-MB02 (for 27mm stroke version) or IR-MB03(for 41/56/96mm stroke version) Metal brackets.
Also, IR-EB01 Rod end bearing is also one of mounting option. Please refer to the mounting manual for each accessory.
Socket head bolts are not included in 27mm stroke version. (they are for 41/56/96mm stroke versions.)
IR-MB03 metal bracket or IR-EB01 Rod end bearing can be another mounting option.
Rod-end tip and Socket-set screw can be used according to user’s need.
Or, user may apply their own rod-end tip(M3 standard). Make sure to put M3 nut before applying rod-end tip.
The M3 nut is a double nut concept for angle adjustment of rod-end tip mounting.
When mounting rod-end tip, make sure to fix the M3 nut and the rod-end tip by the tool(such as long nose) to set angle and to prevent the rod from turning together. (If not, it may cause damage to the product. The rod should not be turned all the time.)
