Product Description:

The AM8551-0EG1-0000 synchronous servo motor from Beckhoff is utilized in applications where a higher moment of inertia is required to maintain synchronism with varying loads. The world recognizes Beckhoff as a top provider of electrical and electronics machinery.

The AM8551-0EG1-0000 servo motor operates in a voltage range of 100 to 480 V AC and consumes a continuous standstill torque (M0) of 4.8 Nm. Its rated speed (nN) is specified at 2500 revolutions per minute which makes it suitable for controlled motion profiles in industrial systems. It meets IP54 protection class with thermal class F insulation. This feature ensures resistance against limited dusty setups and water drops while supporting accurate operation. The rated current of the motor is expressed as 2.7 Arms as this represents the supply stated for rated performance without adding any load on it. Rating voltage (UN) is specified as 400 Vrms in keeping with the usual industrial supply value. The rated power output is (PN) which equals 1.2 kW which is instrumental in supplying adequate mechanical output power for medium duty servo tasks. It also uses the standard EN 60034-1 for rotating electrical machines.

The AM8551-0EG1-0000 servo motor has an integrated brake system operated at 24 V DC using 18 W power which serves the purpose of in-place holding during power-off or emergency stops. The flange code F5 prescribes a mounting dimension of 104 mm. Shaft specifications include a diameter of 24 mm having a tolerance class of K6. It also includes a shaft length of 50 mm for the free end design. The motor has an OCT absolute encoder for giving accuracy in feedback position. Its major certifications include CE, UL and EAC which are certified under E355768.
