Product Description:
The AM8111-1F21-0000 is a synchronous servo motor produced by Beckhoff and supplied within the AM Synchronous Servo Motors series. As a compact rotary actuator, it supplies closed-loop torque and speed control for positioning tables, pick-and-place axes, and other automation tasks that demand precise motion in restricted spaces. Its 40 mm mounting interface allows direct integration with lightweight gear stages or linear modules, helping keep the overall footprint low while maintaining the fast dynamic response associated with permanent-magnet servomotors.
The motor’s mechanical and electromechanical parameters are indicated by several coded identifiers. A flange diameter of 40 mm sets the bolt circle and pilot dimensions for IEC-compliant motor adapters. Winding code F specifies the copper fill factor and rated phase resistance, matching this unit to Beckhoff AX drive families for effective current utilization. Overall length code 1 indicates the shortest stator stack in the subgroup, which minimizes inertia and reduces axial space when the motor is mounted inside a housing. Shaft geometry follows DIN 6885, and the shaft is supplied with a groove and feather key so the hub transmits torque without backlash. Position feedback is provided by an OCT multi-turn encoder that supplies absolute rotor position over multiple revolutions, eliminating the need for homing routines after power loss.
Electrical holding functions are supported by a coil rated at 24 VDC, and the motor includes an integrated 24 V holding brake to secure the load during power-off or emergency stops. The brake delivers a static holding torque of 0.60 Nm, which is suitable for the moment of inertia associated with the motor’s rated load. Power, brake, and encoder conductors are routed through a rotatable angular connector or an optional terminal box, letting the cabling be directed away from moving machine elements. The standard version motor complies with Beckhoff’s AM series envelope dimensions, and its keyed shaft with groove maintains positive drive coupling without additional clamping elements.
