Product Description:
The AM8041-0E21-0000 is a synchronous servomotor manufactured by Beckhoff in the AM Synchronous Servo Motors series. It converts drive current into controllable torque and speed for automated conveyor sections, gantry axes, and pick-and-place stations in industrial cells. This type of motor is intended for servo-controlled axes that require repeatable positioning and stable speed regulation under changing load conditions. The motor is supplied as a standard version, indicating that it does not use special coatings or extended temperature options. Its smooth output shaft and built-in absolute feedback support direct, backlash-free coupling while allowing the controller to detect rotor angle immediately after power-up.
The motor uses an 87 mm flange that fits IEC and ISO mounting patterns used on mid-frame machines. Electrical hookup is simplified by a rotatable angular connector or terminal box, which allows the cable exit to be positioned for the available machine space. Position feedback is supplied through an OCT multi-turn encoder, so the axis can report up to 4096 revolutions without an external battery. The feedback system retains absolute position information through shutdown, which reduces the need for a reference move at startup. The brake provides 9 Nm of holding torque, and its coil operates on 24 VDC. This arrangement helps keep vertical loads in place during power loss or an emergency stop.
The motor includes an integrated holding brake that is factory matched to the rotor inertia for consistent stopping behavior. Motion is transferred by a smooth shaft, eliminating keyways that could introduce slight play in precision couplings. Thermal and electrical behavior matches winding code E, which corresponds to the resistance, inductance, and rated current values used by Beckhoff AX series drives. The housing uses length code 1, the shortest form in the AM8041 family, which helps reduce axis depth in compact machine layouts. Its compact format also supports installation in machines where space is limited but closed-loop servo performance is still required.
