8LSN43.EB060D200-0 by B & R Automation

B&R Automation manufactures the 8LSN43.EB060D200-0 as part of the 8LS Synchronous Motors series, with the internal designation 8LSN. It is a three-phase synchronous servo unit that couples directly to machinery through its mounting flange, allowing compact installation in motion systems that need precise speed regulation and repeatable positioning. Used on packaging stations, pick-and-place heads, and indexing tables, the motor works with a drive controller to translate electrical commands into mechanical rotation for continuous or point-to-point automation tasks. It is intended for applications that require accurate axis control in a compact motor package.

The mechanical interface uses a 100 mm flange dimension and a smooth shaft end, so the motor mounts by flange without foot hardware. A length code of 3 identifies the stack height within the standard configuration family. Power and feedback cables exit through an angled swivel connector that stays clear of linear axes. Rated operation reaches 6000 rpm, supported by an Inductive EnDat feedback system that uses protocol revision 2.1 to transmit position and diagnostic data to the controller. The encoder's multiturn scale delivers absolute position without reset, while single-turn resolution is captured with 19 bits and multiturn counting with 12 bits. This gives the drive both position and status information during operation.

Thermal management relies on a self-cooling housing, so heat is dissipated without external airflow. No external fan is required. Motion can be held at standstill by the integrated standard holding brake, even though no oil seal is present at the shaft. The multiturn mechanism records up to 4096 revolutions, and position data use a 19/12-bit encoder word length, which supports fine synchronization when several axes share a master clock. The motor is supplied in a standard configuration, so the listed cabling, brake, and encoder arrangement remain part of the standard build for this model.
