The AM8122 low-voltage servomotor is suitable for highly dynamic drive solutions in compact design in the voltage range of < 50 V DC. 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 low-voltage servomotor with flange code F2 (58 mm) and motor length 2 has a shaft diameter b = 9 k6 and a free shaft end of d = 20 mm.
