NSM2304
by Kollmorgen
The Kollmorgen NSM2304 servo motor, part of the NSM Brushless Servo Motors series, is engineered by Kollmorgen for demanding industrial automation and motion control applications. It delivers a continuous stall torque of 0.5 Nm (4.4 lb-in) and a peak torque of 1.4 Nm (13 lb-in), ensuring both sustained force and high dynamic response. With a maximum continuous operation speed of 5000 RPM, this compact, lightweight motor excels in precise positioning tasks and rapid start-stop cycles required in robotics, packaging, and high-speed assembly lines.
Under the hood, the NSM2304 features a high-resolution 2000-line incremental encoder for precise feedback on position and velocity. The phase-to-phase winding resistance is 3.18 ohms, and the winding inductance is 4.1 mH, optimizing current response for smooth torque delivery. Torque constants include a sine wave Kt of 0.18 Nm/A and a square wave Kt of 0.20 Nm/A, enabling efficient conversion of electrical input to mechanical output. The rotor moment of inertia is 0.00002 kg·m², which contributes to rapid acceleration and deceleration. Thermal resistance is rated at 3.0°C/watt, supporting reliable operation under continuous load.
Beyond core performance metrics, the NSM2304 supports a radial load capacity of 8 kg at 1000 RPM and maintains low friction torque of 0.014 Nm, minimizing energy loss and wear. The encoder supply runs on 5 VDC, ensuring compatibility with standard drive controllers. Weighing 1.5 kg, this servo motor balances compactness and robust construction for seamless integration into existing systems. Designed for extended service life with minimal maintenance, the NSM2304 enhances throughput and precision in industrial settings, delivering reliable, high-efficiency motion control essential for modern automated processes.
