Engineered for heavy-duty applications, this high-capacity, high-inertia servo family offers 2.9–7.5 kW power and rated torques from 18.6 to 48 N·m, with peak torques up to 120 N·m. Large rotor inertias—reaching 97.1×10⁻⁴ kg·m²—provide exceptional load control and stability for large platforms, high-inertia rollers, heavy moving axes, and continuous-operation industrial systems. With speeds up to 4500 r/min, the series delivers robust, reliable torque for demanding motion environments.
