NEMA 17 High-Performance 2-Phase Stepper Motor (0.48 Nm) STM4238s
- CE
- RoHS
- ISO9001
Engineered for Uncompromising Stability & Zero Downtime
Engineered for precision motion control and ultra-reliability, the STM4238S-0524CM is a high-performance 42mm (NEMA 17) 2-phase stepper motor delivering 0.48 N.m of holding torque. Manufactured under strict ISO9001 protocols with an industry-leading defect rate of <0.3%, this motor utilizes optimized rotor inertia (54 g.cm²) and Class B insulation. It is the definitive choice for system integrators, CNC machinery builders, and OEM applications requiring continuous, drop-in operation without compromise. Fully compatible with standard industrial stepper drives, including the Sefowod DGD223M.
Key Engineering Advantages:
- Industrial-Grade Durability: Features a black electrophoretic end cap and UL1430 AWG26 leads, ensuring maximum environmental resistance in harsh operational conditions.
- Precision Motion Control: Delivers a 1.8° step angle with strict ±5% accuracy and minimal detent torque (2.2 N.cm Max), eliminating resonance and ensuring smooth, predictable rotation.
- Optimized Thermal Performance: Engineered with a low phase resistance (1.72 Ω) and a 2.9V rated voltage, guaranteeing superior heat dissipation during heavy-duty continuous cycles.
- Source Factory Flexibility: 100% proprietary engineering allows for deep-level OEM/ODM customization, including specific shaft modifications, wire harnessing, and complete white-label manufacturing.
- Universal Integration: Standard NEMA 17 (42.3 x 42.3 mm) flange with 4-M3 mounting holes enables seamless deployment as a drop-in replacement or core component in new ecosystem builds.
