The AM8031 standard servomotor is suitable for drive solutions with highest demands on dynamics and performance in the 100…480 V AC voltage range. The standstill torque of the motor depends on the winding and is in the range of < 1.5 Nm. It is available with the OCT feedback system (absolute encoder). The standard servomotor with flange code F3 (72 mm) and motor length 1 has a shaft diameter b = 14 k6 and a free shaft end of d = 30 mm.
