Product Description:

The AM8052-2J21-0000 is a synchronous servo motor produced by Beckhoff within the AM Synchronous Servo Motors series. Designed for closed-loop motion axes, it converts controlled current from a Beckhoff drive into precise rotary movement for pick-and-place stations, feed rollers, or indexing tables. The motor follows a standard build variant, so its mechanical dimensions, electrical windings, and encoder interface match the configuration used across the same family. This layout supports consistent integration in modular machines and multi-axis assemblies used throughout industrial automation.

Cabling can be completed through a rotatable angular connector or terminal box, allowing power and feedback leads to be oriented without changing the machine layout. Position data is supplied by an OCT multi-turn encoder that records absolute shaft position across multiple revolutions, eliminating homing cycles after power loss. The mounting interface uses a 104 mm square flange that centers the stator on standard servo gearboxes or direct-drive frames. A smooth shaft transmits torque through clamp or compression couplings, which can help reduce backlash compared with keyed designs. External contaminants are blocked by a radial shaft-sealing ring with IP65 protection, so the motor can be used in dusty work areas and around incidental coolant spray.

The braking circuit operates on 24 VDC, and the same supply energizes a 24 V holding brake that secures the load when the drive is disabled. Depending on the chosen stack length, the brake can resist between 9 Nm to 20 Nm, which helps keep vertical axes or intermittent-duty tables stationary during stops. Winding code J identifies the winding configuration that sets the motor’s rated current and voltage relationship, while overall length code 2 keeps rotor mass low for high dynamic response. This arrangement suits positioning axes with frequent start-stop cycles and power-off holding requirements.
