The Pololu Bipolar 42×48mm 4V Stepper Motor is a newer, high-performance, low-cost stepper motor designed for energizing a wide range of motion control applications. This stepper motor features a low voltage capacity (4V) and provides 1.2A/phase current output. It is constructed with high-quality windings and a robust 4-pin connector for easy connection. The 4V is perfect for applications that require higher levels of torque, such as those associated with robotics, light industrial tasks, and more. Its low-profile design ensures that it fits into even the most space-restricted mechanical systems, making it ideal for use in robotic arms, 3D printers, and other DIY projects.
