The AM8051 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 4.80…6.30 Nm. It is available with the OCT feedback system (absolute encoder). The standard servomotor with flange code F5 (104 mm) and motor length 1 has a shaft diameter b = 24 k6 and a free shaft end of d = 50 mm.
