8LSA35.E0030D000-0 by B & R Automation

The 8LSA35.E0030D000-0 is a three-phase synchronous motor from B&R Automation and belongs to the 8LS Synchronous Motors series. Within an automation cell, it provides rotary motion for axes that require consistent torque and precise position feedback. The 8LSA designation indicates a standard configuration without reinforced bearings, making the unit suitable for general-purpose handling, packaging, or transfer tasks where high dynamic accuracy is needed but extreme radial loads are not expected.

Its mechanical output reaches a rated speed of 3000 rpm, allowing direct coupling to gear stages or belt drives used in medium-speed production lines. Position feedback is supplied by an optical EnDat encoder that transmits data through EnDat 2.1, and the native resolution of 13/0 bits supports fine incremental moves and absolute referencing within one mechanical revolution. Thermal management relies on self-cooling through free circulation, so the housing dissipates heat into ambient air without forced ventilation. Installation space is set by a flange dimension of 91.3 mm, which aligns with common IEC motor plates, and all power and signal conductors exit through an angled swivel connector that can be rotated to relieve cable strain. The length code 5 indicates the active stack depth, while the absence of a holding brake and the lack of an oil seal reduce inertia and simplify maintenance.

Machine builders secure the stator using a mounting flange that provides a flat, repeatable interface to frames or gearbox inputs. A smooth shaft eliminates keyway stress concentrations and is preferred when clamp or shrink couplings are used for zero-backlash transmission. For applications that only require absolute positioning over one mechanical revolution, the encoder feedback path is limited to a single-turn range, which keeps the feedback data simple while still supporting homing and accurate position tracking.
