High Inertia Motors – for increased stability at low speeds

HJ series of AC servomotors have high inertia rotors along with larger than standard shafts and bearings to provide ultra smooth operation with minimal vibration and resonance when coupled to high inertial loads. Ideally suited for machine tool axis or for applications where the reflected inertia is high. HJ motors are available in 5 frame sizes with a stall torque range of 3 to 67 Nm.
