Product Description:

The AM3043-0E21-0000 servo unit is manufactured by Beckhoff as part of the AM Synchronous Servo Motors series. Classified within the manufacturer’s synchronous servomotors program, the device is intended for precise positioning and speed control in automated machinery, packaging equipment, and handling systems. Its electromechanical construction follows the series' standard version and combines a permanent-magnet rotor with optimized stator windings so that drive controllers can achieve tight loop bandwidths during continuous interpolation tasks.

The flange mounting interface measures 87 mm, giving designers a predictable reference dimension when pairing the motor with standard planetary gearboxes or direct-drive couplings. An integrated brake supplies 9 Nm of static torque to secure loads, and it is released with 24 VDC, allowing direct connection to common control-voltage rails. Shaft position is reported through OCT multi-turn feedback, enabling absolute multi-revolution tracking without external batteries and simplifying power-up homing sequences. Mechanical power is transmitted by a smooth shaft, which avoids key stress points and supports backlash-free clamp collars used in high-precision axes.

Wiring is flexible because the housing carries a rotatable angular connector or terminal box, so power and feedback lines can be turned after installation. The spring-applied 24 V holding brake engages when supply power is removed, matching the previously noted mechanical torque to hold vertical loads. Electrical characteristics are identified by Winding Code E, letting AX-series drives load the correct current and voltage tables automatically. The physical build, denoted by Overall Length Code 3, adds stator depth while leaving the 87 mm flange unchanged for easy retrofit. The motor series type and its version are both standard, providing consistent mechanical geometry across the AM304 range.
