Product Description:

Beckhoff manufactures the synchronous servo motor AM8033-1F21-0000 as part of its AM Synchronous Servo Motors series. The unit converts drive current into continuous rotary motion for precise position and speed control in packaging, handling, and general automation cells. Its standard housing and shaft format allow direct coupling to gearboxes or belts, while integrated feedback and brake features allow it to operate with compatible EtherCAT drives for closed-loop performance.

The motor’s encoder is an OCT multi-turn system that feeds absolute position data to the drive across multiple revolutions, eliminating rehoming after power cycles. A square flange of 72 mm follows IEC mounting geometry so the machine frame can accept the motor without adapter plates. With an overall length coded as 3, this model uses a medium magnetic stack, and its electromagnetic circuit uses F insulation class, allowing higher current density at elevated stator temperatures. The listed holding torque is 2 Nm to 3.5 Nm, giving the brake enough clamping force for indexing tables and vertical axes. Power and feedback cables exit through a rotatable angular connector or a terminal box, making routing flexible inside compact cabinets.

The mechanical interface is secured by a 24 V holding brake that engages automatically when DC power is removed, and it is energized through a dedicated 24 VDC supply line from the control cabinet. Torque is transferred through a shaft with groove and feather key that follows DIN 6885, ensuring interchangeability with standard couplings and pulleys. When the motor is installed, the keyed shaft and brake help keep loads from drifting during service. The rotatable connector maintains strain relief regardless of cable direction, and the standard housing helps protect winding insulation and feedback electronics from production-floor contaminants.
