Product Description:
The AM8071-1TB4B-0000 synchronous servo motor is built by Beckhoff within the AM Synchronous Servo Motors series. Classified in the manufacturer’s Synchronous Servomotors product platform, it serves as a rotary actuator that converts commanded three-phase currents into regulated mechanical output for automated machinery. The motor is designed to pair with Beckhoff drive amplifiers so that conveyor, pick-and-place, and machine-tool axes can achieve fast acceleration, repeatable velocity, and precise positioning. Low cogging torque and integrated feedback make the unit suitable for cyclic or interpolated motion in systems that require controlled speed and accurate movement.
The electrical interface is provided through a rotatable angular connector or an optional terminal box, allowing the cable exit to be aligned with cabinet routing and reducing installation constraints. Rotor position is measured by an OCT multi-turn encoder that delivers 23-bit resolution, giving the drive controller fine granularity for smooth speed control and precise position interpolation. The stator winding marked with code T indicates the voltage constant and thermal class selected for this frame. The rectangular flange measures 194 mm across, matching IEC mounting patterns for large-frame gearboxes and belt transmissions. This flange provides a broad mounting surface that supports stable alignment between the motor and connected equipment during operation.
Mechanical output is transferred through a shaft with a groove and feather key, an arrangement that conforms to DIN 6885 and secures pulleys or couplings against slipping. The motor carries the series-wide construction rating of Standard, indicating a general-purpose housing without liquid-cooling channels or special coatings. Its length designation 1 indicates a short active stack that reduces the space required behind the mounting surface when the motor is installed on compact machine frames. The keyed interface provides positive torque transfer to attached equipment, while the flange helps maintain mechanical alignment under changing loads. These features support installation with common rigid couplings, pulleys, and gearbox input assemblies used in industrial motion systems.
