Product Description:

The AM8112-0F21-0000 is a synchronous servo motor manufactured by Beckhoff as part of the AM Synchronous Servo Motors series. Designed for compact drive technology, it converts electrical input into precise rotary motion for axes in packaging machines, pick-and-place modules, and small machining centers. Permanent-magnet excitation, a concentrated winding layout, and integrated feedback allow the unit to deliver tightly regulated speed and torque when paired with Beckhoff drive controllers. Its compact format is well suited to machine sections where accurate acceleration, repeatable positioning, and limited installation space are all important. Because the feedback device is integrated into the motor housing, the drive can monitor rotor position continuously during motion control tasks.

An electromagnetic brake energized at 24 VDC keeps the shaft locked during power-off states, helping prevent unintended movement when the axis is stopped. A rotatable angular connector or terminal box lets power and feedback leads be routed in a direction that better suits the machine layout. This arrangement supports cleaner cable routing in confined spaces and reduces sharp bends near the motor housing. Position data are transmitted through OCT multi-turn feedback, providing absolute multi-revolution information for startup without a separate homing cycle. Absolute position information is useful on axes that must resume operation with minimal reference movement after a shutdown. The mounting interface uses a 40 mm square flange for compact gearheads and ISO motor plates. Once engaged, the brake resists motion with 0.60 Nm of holding torque. Electrical and thermal behavior correspond to Winding code F, which indicates the coil resistance and current ratings expected by the associated drive.

The integrated 24 V holding brake is supplied as a standard feature rather than an added option. Overall stack depth is identified by Overall Length Code 2, which helps verify enclosure clearance and nearby component spacing during machine layout. Power is transmitted through a smooth shaft, allowing the use of backlash-free clamping couplings and avoiding keyway-related stress concentration. A plain shaft surface also helps maintain concentric coupling alignment in small servo axes that prioritize smooth torque transmission. The standard version keeps the configuration straightforward for compact motion assemblies.
