Built by \u003cstrong\u003eSanyo Denki\u003c\/strong\u003e, this motor features a \u003cstrong\u003e24 VDC (constant current)\u003c\/strong\u003e operating voltage and a \u003cstrong\u003e2 A\/phase\u003c\/strong\u003e current rating, ensuring stable torque delivery. With a winding inductance of \u003cstrong\u003e3.8 mH\/phase\u003c\/strong\u003e and a rotor inertia of \u003cstrong\u003e0.057 × 10^-4 kg·m²\u003c\/strong\u003e, it delivers precise motion control for indexers, pick-and-place systems, and robotic axes.\u003c\/p\u003e\n\n\u003cp\u003eThis motor’s technical prowess includes a phase resistance of \u003cstrong\u003e0.6 Ω\/phase\u003c\/strong\u003e and an insulation resistance of \u003cstrong\u003e≥ 100 MΩ (DC 500 V)\u003c\/strong\u003e, providing electrical robustness. It maintains a static angle error within \u003cstrong\u003e± 0.054°\u003c\/strong\u003e for high-precision positioning. Vibration performance is exceptional: a \u003cstrong\u003e1.52 mm amplitude\u003c\/strong\u003e at 10–70 Hz and \u003cstrong\u003e147 m\/s² acceleration\u003c\/strong\u003e at 70–500 Hz, plus an impact resistance of \u003cstrong\u003e490 m\/s² (11 ms)\u003c\/strong\u003e. These specifications reduce resonance and ensure consistent step accuracy even under shock and vibration.\u003c\/p\u003e\n\n\u003cp\u003eEngineered for reliability, the 103H7121-0410 offers an \u003cstrong\u003eIP40 protection grade\u003c\/strong\u003e to guard against light dust ingress and operates across an ambient temperature range of \u003cstrong\u003e–10 °C to +50 °C\u003c\/strong\u003e. Mechanical tolerances include an axial play of \u003cstrong\u003e≤ 0.075 mm (10 N load)\u003c\/strong\u003e and radial play of \u003cstrong\u003e≤ 0.025 mm (5 N load)\u003c\/strong\u003e, ensuring shaft stability. Its compact \u003cstrong\u003e41.8 mm\u003c\/strong\u003e length eases integration into tight assemblies. By combining durability, low electrical noise, and precise control, this stepping motor enhances throughput, reduces maintenance, and boosts efficiency in industrial automation applications.\u003c\/p\u003e","brand":"Sanyo Denki","offers":[{"title":"Unused Surplus","offer_id":52102167691565,"sku":null,"price":464.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/StepSyn_Stepping_Motors__2e2ce885-2f82-46cf-8c03-a21f2e3fe860.webp?v=1759519598","url":"https:\/\/servosupplier.com\/products\/103h7121-0410","provider":"Servo Supplier","version":"1.0","type":"link"}
