Linear Stepper Motors: These stepper motors with linear motion are open-loop systems with a base and a slider. They provide high speeds and resolutions. The sliders are also called forcers which contain a permanent magnet, teeth, and motor windings.

Linear motors are commonly used for actuating high performance industrial automation equipment. Their advantage, unlike any other commonly used actuator, such as a ball screw, timing belt, or rack and pinion, is that they provide any combination of high precision, high velocity, high force and long travel.

A stepper motor is a device used for precise motion control, while a linear actuator is a linear motion device used for simple linear motion applications. They differ in construction, feedback, and force and speed characteristics, among other factors.

Motion Control Products range of 20mm (NEMA8) Hybrid stepper motors are ideal for applications where size and cost is an important factor. JKONGMOTOR's NEMA 8 stepepr motors can be supplied with a variety of housings, single or double shaft options, winding configurations and IP rating options, JKONGMOTOR can also provide other stepper motor or bldc motor customized, such as brake, encoder, gearbox or integrated step motor...
