8LSN56.EB030D300-0 by B & R Automation

The 8LSN56.EB030D300-0 synchronous servo motor is built by B&R Automation as part of the 8LS Synchronous Motors series. Within an automation cell, the unit converts electrical power into regulated rotary motion for indexing tables, packaging axes, and material-handling stations. By combining a permanent-magnet rotor with stator windings driven by a matched inverter, the motor delivers repeatable velocity and torque for precision positioning sequences common in industrial robotics and CNC peripherals. Its compact housing and encoder interface allow direct integration into machine frames without external adapters.

At its rated speed of 3000 rpm, the motor can run continuously without derating. A flange dimension of 142 mm fixes the bolt circle so the housing mates with standardized plates. Position feedback comes from an Inductive EnDat sensor that operates on EnDat version 2.1 and supplies absolute data after each power-up. The encoder's 19/12 bit resolution divides each turn into fine steps, while the multi-turn counter records 4096 revolutions without a battery. The keyed shaft end drives pulleys or couplings, and length code 6 extends rotor depth to increase inertia for smoother starts.

The motor uses a mounting flange as its mechanical interface, eliminating the need for separate feet or brackets. Heat is removed through a self-cooling design, so no external blower is needed. Cabling exits in an angled connection direction, and the swivel design reduces strain in confined panels. Motion can be secured when power is removed because a standard holding brake is fitted. The motor follows a standard configuration, carries the internal designation 8LSN, and is built as a three-phase synchronous machine without an oil seal, so the shaft area should be kept away from external lubrication sources.
