The AM8542 high-inertia servomotor is suitable for drive solutions with increased moment of inertia to ensure synchronism and optimal ratio of load/motor inertia in the 100…480 V AC voltage range. The standstill torque of the motor is 4.10 Nm. It is available with the OCT feedback system (absolute encoder). The high-inertia servomotor with flange code F4 (87 mm) and motor length 2 has a shaft diameter b = 19 k6 and a free shaft end of d = 40 mm.
