Product Description:

The AM8111-1F20-0000 is a compact synchronous servo motor produced by Beckhoff and assigned to the AM Synchronous Servo Motors series. In automated machinery, the unit supplies precise cyclic torque for positioning axes, pick-and-place heads, and small conveyor stages, and it connects directly to Beckhoff drive controllers for closed-loop motion. It uses permanent-magnet excitation to deliver repeatable acceleration while keeping a compact form factor that fits cabinet-mounted machine modules. Its low rotor inertia also helps the motor respond quickly during short indexing moves and frequent start-stop cycles in packaging and assembly equipment.

The motor uses a 40 mm flange for mounting to the machine frame. Electrical power and encoder lines connect through a rotatable angular connector or an optional terminal box, so the cable outlet can be turned to suit nearby hardware. Rotor position is monitored by an OCT multi-turn encoder, which provides absolute data across multiple revolutions so homing is not required after a power loss. Mechanical coupling to the load is handled by a shaft with a groove and feather key, machined according to DIN 6885, which helps prevent slipping during repeated torque reversals. Electromagnetic behavior is set by winding code F, allowing the matching inverter to apply the proper current and voltage profile for this torque constant.

At an overall housing length of 66 mm, identified as overall length code 1, the motor stays short enough for densely packed axis arrays and other space-limited assemblies. It is supplied without a holding brake, so vertical axes that need static load support must use an external clamp or rely on drive torque to remain in position. The hardware is delivered in the standard version, which uses the baseline feature set for this motor type and does not add special coatings or other custom options.
