Product Description:

The AM8012-1C21-0000 is a synchronous servo motor manufactured by Beckhoff as part of the AM Synchronous Servo Motors series. Designed for integration with compatible drive controllers, it converts electrical energy into precisely regulated mechanical motion for coordinated positioning and velocity control in automated machinery such as small pick-and-place arms, indexing tables, and compact packaging lines. Its compact format also suits installations where responsive servo performance is needed without taking up much mounting space. This makes it useful for axes that require smooth acceleration, repeatable stopping, and stable speed control during frequent cycle changes.

This motor accepts a brake control level of 24 VDC, allowing the external drive to energize the mechanical holding element without an intermediate converter stage. A rotatable connector system simplifies cabling, and the available connection style is a rotatable angular connector or terminal box, so the outlet direction can be aligned with enclosure constraints. Position information is returned through an OCT multi-turn sensor, which feeds absolute multi-revolution data back to the controller for immediate position reference after startup. The mounting interface follows a 40 mm square flange, letting the unit fit standard motor plates. During power-off retention, the brake secures the shaft with 0.60 Nm of torque, which helps prevent drift in vertical or high-inertia axes.

The integrated brake acts on a shaft output that uses a shaft with a groove and feather key for positive torque transmission. This arrangement follows DIN 6885, which establishes the key and groove form used at the output. Internally, the stator uses the manufacturer’s C winding pattern, which sets the voltage constant and thermal loss profile. Mechanical depth is limited by the size 2 overall length code, keeping the assembly short enough for confined servo compartments while still supporting the continuous power expected from the series. The keyed shaft format helps resist slip under changing loads, and the short housing is useful where nearby machine components leave limited clearance around the motor body.
