Overview

A Nema 11 stepper motor is a stepper motor with a 1.1 x 1.1 inch (28 x 28 mm) faceplate. Nema 11 high torque stepper motors feature high torque density in a small package. These high torque stepper motors deliver great value with no quality sacrifice. These motors are engineered to provide the highest possible torque but minimize vibration and audible noise. A wide range of motor windings and stack lengths are readily available, or the motors can be customized to meet your machine requirements. The standard 4 wire motors can be connected to give you more flexibility in your application. STEPPERONLINE can also have the windings customized to perfectly match your voltage, current and maximum torque at operating speeds.

NEMA stepper motor sizes depend on the frame size of the stepper motor. NEMA means the standards set by “National Electrical Manufacturers Association”, which is comprised of 560 major electrical manufacturers in the United States, primarily consisting of manufacturers of equipment and devices for power generation, transmission, distribution, and power applications. The purpose of standard setting is to eliminate misunderstandings between electrical product manufacturers and users and to specify the safety of these product applications.

This mini nema 11 bipolar stepper motor with step angle 1.8deg and size 28x28x31mm.

It has 4 wires, each phase draws 0.35-0.95A at 2.52-4.56V, with holding torque 4.5-12Ncm (3.37-16.98oz.in).
