NexBot Robotics STP113-005 NEMA 23 Stepper Motor 1.9 Nm

Overview

The NexBot Robotics STP113-005 is a high-performance stepper motor engineered for demanding positioning tasks within automated and robotic systems. This NEMA 23 frame motor provides a robust solution for applications requiring precise, repeatable motion control without the complexity of a closed-loop servo system. Its primary use is in driving smaller axes, positioning auxiliary equipment, and executing high-accuracy movements in compact robotic cells. Key to its performance is a high-density stator and optimized rotor design, which enables it to deliver a substantial holding torque of 1.9 Nm. This high torque-to-size ratio ensures the motor can hold a load securely in position and overcome inertia during acceleration, which is critical for pick-and-place or assembly operations where component placement must be exact. With a standard step angle of 1.8 degrees (200 steps per revolution), the motor provides fine positional resolution. When paired with a microstepping driver, its movement becomes exceptionally smooth, reducing vibration and mechanical noise—a significant benefit for systems handling delicate components or performing inspection tasks. The STP113-005 operates efficiently across a 24-48VDC voltage range, making it compatible with common industrial power supplies. Its standardized NEMA 23 mounting face and shaft dimensions simplify mechanical integration into existing designs or new equipment. This motor is frequently deployed in the wrist axes of collaborative and SCARA robots, where its balance of torque, precision, and compact size is ideal. It is also well-suited for automated tooling, indexing tables, and focus mechanisms in machine vision systems. Built for reliability in industrial environments, the motor features a durable housing and high-quality construction to ensure a long operational lifespan. For maintenance, routine inspection for secure mounting and clean operating conditions is recommended. The STP113-005 motor represents a dependable component for achieving cost-effective, high-precision motion control.
