AM8553 Servomotor with increased moment of inertia 11.4 Nm (M0), F5 (104 mm)

AM8553 | Servomotor with increased moment of inertia 11.4 Nm (M0), F5 (104 mm)

The AM8553 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 400…480 V AC voltage range. The standstill torque of the motor depends on the winding and is in the range of 10.1…20 Nm. It is available with the OCT feedback system (absolute encoder). The high-inertia servomotor with flange code F5 (104 mm) and motor length 3 has a shaft diameter b = 24 k6 and a free shaft end of d = 50 mm.
