Product Description:
The AM277S-1021 synchronous servo motor is produced by Beckhoff and belongs to the AM Synchronous Servo Motors series. It drives rotary axes that require high positional accuracy and repeatable speed profiles in automated assembly stations, gantry systems, and secondary packaging equipment. When paired with a compatible drive controller, the motor provides controlled torque and rapid acceleration for coordinated multi-axis motion. This combination supports precise starts, stops, and position holding during process changes and dwell periods.
Its power interface supports a brake line rated at 24 VDC, which allows the motor brake to be released or engaged independently of the main phase conductors. A square 194 mm flange matches heavy-duty gearboxes or direct machine frames and helps maintain accurate alignment during installation. When energized, the electromagnetic stack can produce up to 70 Nm of static holding torque, allowing the axis to resist external loads at standstill. Position feedback is delivered through an OCT multi-turn encoder that provides absolute position data over multiple revolutions, which reduces the need for repeated homing after power cycles. Power is transmitted through a shaft with a keyway and feather key, providing a positive mechanical connection for couplings or pulleys.
The integrated 24 V holding brake secures the rotor during emergency stops and while gravity acts on vertical axes. Compliance with DIN 6885 governs the shaft interface dimensions, which supports direct coupling to standard transmission elements without additional machining. The motor uses a standardized connection layout for its mechanical, electrical, and feedback interfaces across the AM Synchronous Servo Motors range. This helps machine builders scale axis performance without changing mounting plates or cabinet wiring.
