Product Description:
The AM8043-1E00-0000 is a synchronous servo motor produced by Beckhoff for the AM Synchronous Servo Motors series. As a compact rotary actuator, it supplies precisely controlled torque and speed for closed-loop motion systems. The motor supports positioning axes, packaging equipment, and pick-and-place gantries that require accurate and repeatable movement.
The motor bolts to machinery through an 87 mm square flange that establishes the lateral footprint for gearbox or direct-drive couplings. Power and signal leads exit through a rotatable angular connector or a terminal box, allowing the cabling to be oriented without turning the housing. Rotor position is returned by a two-pole resolver, which provides analog sine-cosine feedback that compatible drives can interpolate at high sampling rates for smooth velocity regulation. Because the unit is supplied without a holding brake, vertical axes must rely on external clamping or drive torque when power is removed. The shaft geometry conforms to DIN 6885, so the keyway dimensions follow an established industrial standard for compatible mechanical couplings.
The mechanical output uses a shaft with a groove and feather key that prevents pulleys or pinions from slipping during acceleration. Internally, an E-code winding uses copper turns and wire sizing that provide electrical resistance and inductance values suited to compatible Beckhoff drives and midrange current requirements. The stator stack uses length code 3, balancing thermal capacity with dynamic response during repetitive start-and-stop duty cycles. The motor is delivered in a standard version that uses the base housing dimensions and sealing arrangement for this motor type. Its keyed shaft provides positive torque transfer where clamping couplings alone may not offer sufficient resistance to sudden load changes. The resolver supplies continuous angular information to the drive, allowing the control loop to correct speed and position as operating loads change. Cable orientation can be adjusted to accommodate confined machine layouts while reducing unnecessary bending near the connection point.
