8LSN58.EB022D900-0 by B & R Automation

The 8LSN58.EB022D900-0 is a three-phase synchronous motor manufactured by B&R Automation for the 8LS Synchronous Motors series. It couples directly to machinery through a mounting flange and delivers rotary power for positioning axes, gantries, and conveyor stations in automated lines. The 8LSN designation identifies it as a standard variant in the series, with a compact format intended for use with matching drive systems. This arrangement allows the motor to serve as a direct-drive element where accurate motion and compact installation space are both important.

A flange dimension of 142 mm sets the bolt circle and the required frame opening in the machine housing. Power and feedback conductors exit the stator through an angled swivel connector, allowing the cable package to be routed parallel to the motor face when space behind the flange is limited. At a rated speed of 2200 rpm, the rotor provides stable operating speed for typical servo applications in this size class. Rotor position is measured by an Inductive EnDat encoder, and version 2.1 supports bidirectional digital communication so the drive can read absolute position, diagnostics, and electronic nameplate data without additional wiring.

The motor uses self-cooling, so heat is dissipated through the housing and normal operating airflow without the need for an external blower. A standard holding brake keeps the load stationary when the drive is disabled, and an integral oil seal helps limit lubricant migration along the shaft. Feedback resolution reaches 19/12 bits for single-turn and multi-turn counting, while the multi-turn counter tracks up to 4096 revolutions so position information remains available after power loss. The keyed shaft transmits torque without slip, and the length code 8 housing provides additional internal space for the winding.
