Model: NEMA11 Captive Linear Actuator Stepper Motor-JK28HSK (1.8 degree)
Each phase draws 670 mA at 6.2 V, allowing for a holding torque of 1.2 kg.cm. With a small frame size of 28x28mm, this is a stepper motor for robotic or CNC applications where weight is a concern.
The captive actuator has a built in anti-rotation mechanism through the use of a splined output shaft that allows it to extend and retract as a unit with no requirements for additional anti-rotation. The captive actuator is designed for shorter strokes.
In addition to providing high-performance hybrid stepper linear motors, Jkongmotor provides high-quality leadscrews and nuts, opening up new avenues for equipment designers who need high performance and superior durability. The Jkongmotor's actuators generate more force than similar actuators due to their special stator geometry and optimized magnet materials.
Our proven permanent magnet linear actuators are ideal for simple designs with lower performance requirements.
There are four types of linear stepper motors: external drive linear stepper motors (including T-type lead screw and ball screw), Captive linear stepper motors and Non-Captive linear stepper motor
