Product Description:

The AM8551-1E00-0000 is a synchronous servo motor produced by Beckhoff within the AM Synchronous Servo Motors series. It serves as a compact drive element that links directly to a servo amplifier, delivering closed-loop speed and position control for pick-and-place units, gantry axes, and other precisely coordinated automation tasks. The motor is supplied in the standard version, so no special environmental reinforcements or custom balancing measures are included.

This model mounts to a machine frame with a flange diameter of 104 mm, a size that aligns with common planetary gearheads and couplings. Position data are returned through a two-pole resolver, giving analog feedback for drive algorithms that tolerate electrical noise and high temperatures. Power and signal lines exit through a rotatable angular connector or terminal box, and either option allows the cable outlet to turn for easier routing in tight enclosures. The motor is supplied without a holding brake, so external locking devices are required when static torque at power-off is needed. Its rotor is built for an increased mass moment of inertia, allowing smoother speed regulation when it is coupled to sizable loads that might otherwise amplify velocity ripple.

The drive side uses a shaft with groove and feather key, permitting positive-fit torque transfer in accordance with DIN 6885 keyway dimensions. Mechanical depth follows overall length code 1, which gives a predictable housing length for stack-up calculations in multi-axis layouts. Coil parameters follow winding code E, which determines the voltage constant and rated current range that must match the chosen servo amplifier. These features support straightforward integration in resolver-based motion systems where keyed shaft transmission and stable feedback are required.
