Model: 2 Phase Hybrid Nema 8 Non-Captive Linear Stepper Motor 20*20mm-JK20HSC(1.8 degree)
External mechanical components separate from the motor are introduced into the design to keep the lead screw from rotating. The lead screw moves back and forth axially by restricting its rotation, which then drives the device it is attached to back and forth.
Jkongmotor's NEMA 8 series are very small high torque stepper motors that can reach up to 3000 rpm. These motors are used in the model making and maker scene as well as in the industrial environment (e. g. positioning of optics, dosing pumps, interlocks, etc.).
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.
Jkongmotor 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...
