Product Description:

The AM3031-0C21-0000 is a synchronous servo motor manufactured by Beckhoff and belongs to the AM Synchronous Servo Motors series. It is supplied as a standard version unit that converts electrical energy into controlled rotary motion for machinery that requires accurate speed and position control. When paired with a compatible servo drive, the motor supports closed-loop movement in automated assembly systems, packaging equipment, and material handling machines. This layout makes it suitable for applications where repeatable positioning, stable speed control, and compact motor dimensions are important.

The motor uses a flange measuring 72 mm, allowing direct installation on compact machine frames or gear units. Its holding brake operates on 24 VDC, so the shaft can be secured during a controlled stop or after power is removed. Depending on the overall motor length, the brake can provide between 2 Nm to 3.5 Nm of holding torque for standstill load retention. Position feedback is provided by an OCT multi-turn encoder, which supplies absolute position data over multiple revolutions and allows the drive to detect shaft location immediately after startup. Torque is delivered through a smooth shaft, which is intended for clamping-style couplings and avoids the stress concentrations associated with keyed designs.

Electrical connections are arranged through a rotatable angular connector or terminal box, allowing cable routing to be oriented to fit the available installation space. A built-in holding brake provides mechanical retention during power-off conditions, which is useful when the axis must remain stationary at rest. The motor uses length code 1, indicating the shortest housing option in the AM3031 family and helping reduce axial space requirements in compact machines. Its electromagnetic setup follows winding code C, which matches the motor to the corresponding drive settings for current response and thermal behavior. These features support straightforward integration into servo axes that need compact packaging, absolute feedback, and dependable standstill holding.
