25mm PM Stepper Motor with Planetary Gearbox

Features
Compared with 15mm series PM stepper motors, our 25mm series motor has been increased in motor size (with a housing diameter of 25mm) to produce higher holding torques for different applications.

This stepper motor operates on the attraction or repulsion between a permanent-magnet rotor and an electromagnetic field. Normally we use ferrite sintered magnet to form into a PM rotor.

From the picture, you see that our 25mm PM stepper motors are built with a planet gearbox, whose main material is POM. Currently we offer 2 options in speed ratio, one being 1:76 and the other, 1:30.3.

Planetary gearboxes are used in applications that require low backlash, compact size, high efficiency and resistance to shock. Our 25mm PM stepper motor assembled with the aforesaid gearboxes have been well known in motion control industry due to a highly efficiency in power transmission and greater stability.

Applications
The motor is often found in precise automotive instrumentations, medical equipment and machine tools.
