SPF NEMA16 Bipolar Stepper Motor 12V 1.8 0.33A 2.3kg cm 4-Wire

The SPF NEMA16 12V Bipolar Stepper Motor (ROB-09238) is a compact, high-precision stepper motor designed for robotics, CNC equipment, automation systems, and motion control applications. Featuring a standard NEMA 16 mounting pattern, this reliable 2-phase bipolar motor provides accurate positioning, smooth rotation, and excellent holding torque, making it an ideal choice for projects requiring repeatable and controlled movement.

Operating from a 12V supply with a rated current of 0.33A per phase, the motor offers a 1.8 step angle, providing 200 full steps per revolution for precise positioning without the need for feedback sensors in many applications. Its 2.3kg cm holding torque delivers dependable performance for light to medium-duty motion control tasks, including linear actuators, camera sliders, robotic arms, pan-and-tilt mechanisms, and laboratory automation.

The motor features a 4-wire bipolar configuration, making it compatible with a wide range of popular stepper motor drivers such as the A4988, DRV8825, Big Easy Driver, TB6600, and other compatible bipolar stepper motor controllers. A factory-fitted cable simplifies installation and reduces wiring time during project assembly.

Constructed with a 5mm diameter drive shaft and a 42mm motor body, the motor is suitable for coupling to gears, pulleys, lead screws, and timing belts. The standard 31mm NEMA 16 mounting hole pattern ensures easy integration into new designs or existing motion systems.

Whether you're building a CNC machine, educational robotics platform, automated positioning system, or custom engineering project, the SPF NEMA16 Stepper Motor delivers the precision, reliability, and smooth operation needed for demanding motion control applications.
