Model: 2 Phase Hybrid Nema 8 Captive Linear Actuator Stepper Motor 20*20mm-JK20HSK(1.8 degree)
NEMA is an acronym for the National Electrical Manufacturers Association which took it upon itself to start standardizing motor sizes using certain criteria. NEMA frame sizes include designations that can help you learn more about the size and capability of practically any particular motor.
NEMA 8 frame (20mm square) is the smallest size of hybrid stepping motor. We supply NEMA 8 stepper motor with 1.8 degree step angle and a weight of only 50g. We also customize the winding to perfectly match your voltage and current. If you want to buy NEMA 8 stepper motor, Our company is definitely your best choice. Our Step motor technology utilizes a simple design to create an effective solution for many applications requiring reasonable accuracy and torque. Get a stepper motor that meets your requirements precisely.
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.
The captive linear stepper consists of an internal threaded shaft connected to an anti-rotational element and external spline shaft. An extended housing with a mating spline element at the end allows the spline portion of the shaft to extend and retract from the actuator housing.
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...
