A Nema 8 stepper motor is a stepper motor with a 0.8 x 0.8 inch (20 x 20 mm) faceplate. Nema 8 high torque stepper motors provide high torque in a compact size. The design of these motors is to provide the highest possible torque but minimize vibration and audible noise. A large selection of motor windings and stack lengths can be selected, or you can customize the motor to meet your machine requirements. Motors are available in a standard 4-lead configuration. We can also have the windings customized to perfectly match your voltage, current and maximum torque at operating speeds. Special shaft modifications, cables and connectors can also be provided upon request.
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.
A Manufacturer’s Certificate of Origin, also known as a Manufacturer’s Statement of Origin, is a specified document certifying the country.
