NexBot Robotics STP113-009 Stepper Motor 1.9 Nm

Overview

The NexBot Robotics STP113-009 is a high-torque stepper motor engineered for precise positioning and velocity control in automated systems and industrial robotics. This component is designed to deliver consistent, step-by-step motion, making it an ideal choice for applications where accuracy is critical and feedback systems are not required. The core of the STP113-009's performance lies in its robust design, which provides a holding torque of 1.9 Nm. This substantial torque ensures that the motor can hold its position firmly against external forces, preventing unintended movement and maintaining the integrity of the robotic task. With a standard 1.8° step angle (200 steps per revolution), the motor offers fine resolution for detailed and accurate positioning tasks. This precision is essential for applications such as the fine-adjustment of end-of-arm tooling, precise dispensing, or component placement where even minor deviations can impact quality. Constructed for longevity in demanding industrial environments, the motor features a durable anodized aluminum housing and high-quality internal components that resist wear and thermal stress. The design facilitates efficient heat dissipation, allowing the motor to operate reliably over extended periods without significant performance degradation. An IP40 rating protects the internal workings from solid objects larger than 1mm, ensuring durability in typical factory floor conditions. The standardized NEMA 23 frame makes it a direct drop-in replacement or an easy-to-integrate component for new designs, simplifying both maintenance and system builds. Typical applications for the STP113-009 stepper motor include driving auxiliary axes on collaborative robots, controlling the orientation of tooling, or powering small-scale pick-and-place mechanisms. Its reliability and precision are well-suited for tasks in electronics assembly, laboratory automation, and material handling where repeatable motion is paramount. The motor operates on a common 24VDC power supply, aligning with standard industrial control system voltages. For proper operation, it must be paired with a compatible stepper motor driver capable of supplying the required current to achieve its rated performance. This ensures smooth micro-stepping and minimizes resonance, resulting in quieter operation and enhanced motion quality.
