Description

General part information

QSH2818 Series

NEMA11 (28mm) 2-phase stepper motor optimized for microstepping and give a good fit to the ADI TRINAMIC family of motor controllers and drivers. They can be used in very space critical applications and allow high RPM due to their low back EMF.Variants include small size optical incremental encoder kit. It comes with a resolution of 8192 lines (32768 counts). ADI Trinamic’s stepper motors are quality motors for universal use. They feature a long life due to ball bearings and no wearing out parts.
