NEMA Stepper Motor Product Description
Our NEMA Stepper Motor series meets unified dimensional standards set by the National Electrical Manufacturers Association, covering full NEMA11/17/23/34 sizes for automation equipment.
Our NEMA stepper motor lineup includes NEMA 11, 17, 23 and 34 models.
These sizes match mainstream 28mm, 42mm, 57mm and 86mm frame standards.
They fit most industrial automation and desktop precision machines.
Furthermore, all models have universal standard mounting sizes, so they can replace motors from other brands directly.Our NEMA stepper motors use premium winding coils and precise mechanical frames.
In addition, they carry a standard 1.8° step angle and support half-step and multi-microstep drive.
Therefore, this design brings zero cumulative positioning error, stable rotation and low running noise.
The product lineup covers a complete power range from micro to industrial grades, including 5V low-voltage geared motors and 12V/24V industrial universal motors. It works stably with mainstream driver modules such as ULN2003, A4988, and TB6600. Featuring solid construction and excellent load-bearing capacity, the motors deliver progressively increased holding torque across different specifications, suitable for both light-duty precision transmission and heavy-duty industrial operation. Equipped with reliable wide-temperature adaptability and basic dustproof performance, these motors maintain stable performance in diverse working environments.
Compatible with multiple control methods including single-chip microcomputers, PLCs, and serial port web control, this series of stepper motors is widely applied in 3D printing, intelligent PTZ cameras, smart home transmission systems, small valve control, engraving machines, automated production lines and other civilian and industrial fields. It serves as a core universal accessory for high-precision automatic control and intelligent equipment transmission systems.
