AM8051-1E20-0000 by Beckhoff

The AM8051-1E20-0000 synchronous servo motor is produced by Beckhoff within the AM Synchronous Servo Motors series. This rotary unit converts commanded current into tightly regulated torque and speed, making it a common axis solution for packaging stations, pick-and-place robots, and material-handling gantries. By pairing with Beckhoff EtherCAT drive modules, the motor enables coordinated multi-axis motion, supports quick cycle times, and maintains repeatable positioning accuracy in automated equipment. Classified as a standard motor series type, it offers consistent dimensions that simplify machine design across multiple frame sizes.

The motor uses a rotatable angular connector or terminal box so the power and feedback plugs can be oriented to match cabinet layouts and avoid cable stress. Position feedback is provided by an OCT multi-turn encoder that returns absolute rotor position over many revolutions, eliminating the need for homing after power-up. A flange diameter of 104 mm sets the mounting interface for this frame size. The rotor is supplied without a holding brake, so an external clamp is required when power-off torque retention is needed. Its mechanical envelope uses overall length code 1, which corresponds to the shortest stack offered for this frame and helps reduce axis depth in compact machines.

Mechanical power is transferred through a shaft with groove and feather key, and the keyway follows DIN 6885 for coupling alignment and secure torque transfer under load. The winding code E sets the rated current and voltage pairing used with Beckhoff servo drives. The motor is supplied in the Standard version, meaning no special coatings or special bearing options are applied. This arrangement keeps the mechanical interface consistent across installations and supports integration into compact automation hardware.
