NEMA 16 39HM 0.9° 2-Phase Hybrid Stepper Motor

Product Display

A Nema 16 stepper motor is a stepper motor with a 1.6 x 1.6 inch (39 x 39 mm) faceplate. Nema 16 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 motors are wired as a standard configuration with 4-lead for the bipolar series. We can also customize the windings to perfectly match your voltage, current and maximum torque at operating speeds. Additional lead configurations can be offered upon request, along with cable and connector options. It is also possible to add encoders and brakes to suit your customized application.

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.
