We deliver 400g-cm start torque and ≤1.2V start voltage. Our 8V DC motor series integrates high insulation resistance (≥1MΩ) and wide temperature tolerance (-20°C~60°C). We customize windings, shaft dimensions, and speed-torque curves — we eliminate guesswork. Deploy ready-to-integrate modules for robotics, medical pumps, and industrial actuators.

✅ 200±10% rpm no-load ✅ 170±5 rpm @200g load ✅ ≤0.4A start current ✅ Any orientation operation
