Product Description:

The AM8041-1E21-0000 is a rotary servo unit produced by Beckhoff in the AM Synchronous Servo Motors series. With an overall length code of 1 and a standard winding set, the motor fits tasks that need medium continuous torque without extended housing depth. It converts electrical energy supplied by a matched AX5000 drive into controlled mechanical power, enabling indexed positioning, coordinated multi-axis motion, and stable speed control in packaging, assembly, and material-handling equipment. Its servo design supports responsive acceleration and repeatable motion during frequent start-and-stop cycles.

The motor is built on an 87 mm mounting interface, allowing installation on machine connections that follow IEC dimensional rules. Rotor position and revolution count are returned through an OCT multi-turn encoder, giving absolute feedback without external batteries. This feedback allows the control system to detect shaft position immediately after startup and maintain synchronized motion across linked axes. Electrical release of the brake requires 24 VDC, and when engaged, the braking element can hold up to 9 Nm to secure vertical axes. Power, feedback, and brake conductors enter through a rotatable angular connector or terminal box, so the cable outlet can be oriented after installation to reduce bending stress and simplify routing.

The mechanical side is completed by a shaft with groove and feather key cut according to DIN 6885, which supports secure torque transmission to standard hubs. When the axis must remain stationary during power-off, a 24 V holding brake is integrated to hold the load in place. The electromagnetic section follows winding code E, which pairs the stator with drive modules tuned for its resistance and inductance. Beckhoff marks the build as a standard motor series type and standard version. The motor is intended for applications that need accurate stopping, repeatable positioning, and compact installation.
