Product Description:
The AM8122-0J00-0000 is a synchronous servo motor produced by Beckhoff and assigned to the AM Synchronous Servo Motors series. It is intended for closed-loop positioning and velocity control in compact automation axes where high dynamic response and precise feedback are required. Within an installation, the motor links directly to a drive controller to convert electrical commands into mechanical rotation for tooling, handling equipment, or small conveyor applications. Its permanent-magnet design supports responsive torque generation when paired with a compatible servo drive.
The mechanical interface uses a 58 mm square flange that mates with corresponding gearboxes or machine frames. Power and feedback lines exit through a rotatable angular connector, allowing cable runs to be oriented without placing excessive stress on the conductors. Rotor position is reported by a two-pole resolver, which provides analog sine-cosine feedback suitable for demanding environments and high shaft speeds. Motion is transferred through a smooth shaft, so couplings rely on friction clamping or adhesive bonding rather than key engagement. This shaft arrangement can help minimize runout in precision assemblies while providing a uniform coupling surface.
The motor’s electromagnetic characteristics are grouped under winding code J, which balances torque density with thermal limits for medium-power compact drives. The design belongs to the Compact Drive Technology platform, which provides dimensional compatibility with short-depth servo controllers used in distributed cabinets. The unit is supplied without a holding brake, making external load retention necessary when an axis must remain stationary after motor power is removed. The absence of a brake also reduces motor mass and rotor inertia, supporting faster acceleration during repetitive motion cycles. The motor is supplied in the standard version, with no special surface coating or additional sensor option installed. Its connector orientation, flange dimensions, feedback method, and shaft style support installation in space-constrained automation equipment that requires accurate motion control.
