8LSA44.EA030D100-3 by B & R Automation

The 8LSA44.EA030D100-3 belongs to the 8LS Synchronous Motors series produced by B & R Automation. This servomotor is used in industrial automation lines to deliver repeatable torque and speed for positioning tables, packaging axes, and other motion tasks that depend on coordinated drive control. It is intended for closed-loop motion systems in which the drive continuously corrects speed and position during changing loads. That makes it suitable for automated stations that repeat the same travel pattern over long production runs. Because a holding brake is not present, any static load must be secured by the drive controller or an external locking device.

It is a three-phase synchronous unit that reaches a rated speed of 3000 rpm, which suits medium-inertia loads common in conveyor and indexing equipment. A mounting flange with a 100 mm square interface supports direct coupling to machine frames, while the power and feedback leads exit through an angled swivel connector housing that eases cable routing in tight cabinets. This arrangement helps the motor fit compact machine layouts where cable space is limited. Heat is removed by a self-cooling air path, so no external blower or liquid circuit is required. The configuration is designated 8LSA, indicating the standard build without reinforced bearings, and length code 4 indicates the stack height. The absence of an oil seal suits applications that run in clean, dry atmospheres.

Feedback is generated by an integrated inductive EnDat sensor that operates with EnDat 2.1 protocol for bidirectional communication. Position data are delivered at 19/0 bit resolution, and the encoder is limited to single-turn measurement, which suits axes that reference once per cycle. A shaft end machined with key provides positive torque transfer to pulleys or couplings. This shaft style is useful where torque must be transmitted without slip during frequent starts and reversals. Product revision 3 implements the current connector pinout, and the standard bearing arrangement meets lifetime expectations when radial forces remain within the permitted range.
