Product Description:

The AM8043-0E21-0000 is a synchronous servo motor manufactured by Beckhoff as part of the AM Synchronous Servo Motors series. Designed for demanding positioning and velocity loops, the motor converts electrical energy into precise rotary motion for automated machinery, pick-and-place axes, and packaging lines. It belongs to the manufacturer’s Standard motor type, providing a balance of torque density and footprint for general-purpose tasks across industrial automation cells. Integrated features such as an optional holding brake and electronic feedback allow the drive controller to maintain accurate control under dynamic load changes.

The brake coil requires a control voltage of 24 VDC, allowing the drive cabinet to power the brake directly from common auxiliary supplies without a DC–DC converter. Position data are returned through an OCT multi-turn encoder, which transmits absolute rotor angle over multiple revolutions so homing cycles are unnecessary after power loss. A mounting interface sized at 87 mm flange complies with IEC dimensions, simplifying interchange with other motors of the same frame. When the brake is engaged, the shaft can resist up to 9 Nm of static load, preventing drift on vertical axes. Power, brake, and feedback conductors are brought out through a rotatable angular connector or an alternate terminal box, giving flexible cable routing in tight enclosures.

Mechanical transmission from the motor is via a smooth shaft, so couplings must rely on friction or external keying devices instead of an integrated keyway. The overall package length follows code 3, helping machine builders predict clearance behind the flange when drafting layouts. For holding duties the motor can be ordered with a 24 V holding brake that engages automatically when the drive is disabled. Electrical performance is matched to drive inverters labeled with E winding code, while the Standard version and Standard series type ensure consistent thermal ratings across comparable models.
