Product Description:

The AM257S-0001 is a synchronous servo motor produced by Beckhoff and belongs to the AM Synchronous Servo Motors series. It is designed to provide closed-loop rotary motion in automated machinery where precise positioning and repeatable speed control are required. When used with compatible drive amplifiers and the TwinCAT control platform, the motor converts commanded position values into mechanical rotation for handling, packaging, and machining axes. This arrangement lets the axis follow speed changes, positioning moves, and stop commands with repeatable motion during automated operation.

The brake uses 24 VDC, so the coil can be powered from common control-voltage supplies. Position feedback is provided by a two-pole resolver, which returns analog rotor-angle signals with strong noise immunity in industrial environments. Because the resolver is analog, it remains suitable where long motor leads or electrically noisy cabinets are present. A 194 mm square flange supports rigid mounting to large gearheads or machine frames, and the brake can hold up to 70 Nm during static or emergency stops. The output is a smooth shaft, which allows coupling without a keyway and suits connections that rely on clamping rather than keyed engagement.

The motor includes a holding brake and an internal rotor package with an increased mass moment of inertia, which supports stable control on heavier drive trains and helps smooth load transitions. Within the Synchronous Servomotors portfolio, this configuration suits axes that need fast settling while still benefiting from added rotational energy storage. Combining the brake, resolver, and mechanical interface in one housing reduces external wiring on multi-axis assemblies. The arrangement is well suited to rotary index tables, conveyor gantries, and other equipment that must hold position accurately during continuous-duty operation.
