Product Description:

The 8LSA35.EA030D000-0 is a three-phase synchronous motor produced by B & R Automation and supplied in the 8LS Synchronous Motors series. Intended for industrial automation, the unit converts controlled electrical power into precise rotary motion for positioning or speed-regulated axes. It is part of the 8LSA configuration, a standard build without reinforced bearings, aimed at general machinery that demands compact size and reliable servo performance. It is also well suited to compact packaging, assembly, and transfer systems that use coordinated servo motion.

The motor reaches a rated speed of 3000 rpm, enabling direct coupling to equipment that operates in that velocity range without reduction gearing. A mounting flange diameter of 91.3 mm establishes the mechanical interface and helps maintain axial alignment. Power and feedback conductors exit through an angled swivel connector, allowing flexible cable routing as the axis moves. The output shaft is a smooth shaft, which suits press-fit hub connections where keyways are unnecessary. The motor is supplied without an integrated brake, so load retention during power loss must be handled by external devices or drive torque. This arrangement is useful on axes where holding force is managed elsewhere in the machine design.

Thermal management relies on a self-cooling design that uses free air circulation, eliminating fans or liquid loops in typical enclosures. Position data are delivered by an Inductive EnDat encoder that uses protocol version 2.1, which supports automatic parameter upload and extended diagnostics. The encoder has a resolution of 19/0 single-turn/multi-turn bits, providing fine angular detail within each revolution. The motor has length code 5, connector-based wiring, and no oil seal, making it suitable for standard environments. It is often used where direct feedback connectivity and compact installation are important.
