Product Description:

The AM8131-1F21-1001 is a synchronous servo motor produced by Beckhoff within the AM Synchronous Servo Motors series. It is intended for precision positioning and speed control in automated machinery, where compact size and integrated electronics minimize cabinet space on densely packed axes. The motor combines electromagnetic torque generation with an internal brake circuit so that motion axes can be held when power is removed. Because it belongs to Beckhoff's Synchronous Servomotors product line, it interfaces directly with compatible servo drives for closed-loop control in high-performance packaging, handling, and assembly systems.

The brake coil is energized at 24 VDC, allowing the brake to release or engage from standard control power. Position feedback is delivered through an OCT multi-turn encoder, which returns absolute shaft angle across multiple revolutions and removes the need for homing after startup. The motor uses a mounting flange of 72 mm to match standardized gearboxes and mechanical frames. An integrated 24 V holding brake secures the load during emergency stops or when the drive is disabled, and its retention capability ranges from 2 Nm to 3.5 Nm, depending on the chosen mechanical length. Winding code F sets the stator turns and copper cross-section so that current, voltage, and thermal behavior align with the drive rating.

The motor uses length code 1, the shortest variant in the AM8131 group, which reduces mass and inertia for fast indexing cycles. Power is transmitted through a shaft with groove and feather key, preventing rotation between the shaft and coupled hubs in compliance with DIN 6885. This keyway execution is delivered as a special version rather than the plain-shaft standard while maintaining balance for high-speed service. The keyed output suits couplings and hubs that need positive torque transmission.
