8LSA35.R0030D100-0 by B & R Automation

The 8LSA35.R0030D100-0 is a three-phase synchronous servo motor produced by B & R Automation within the 8LS Synchronous Motors series. The unit converts drive current from a matched inverter into rotary motion for positioning axes, conveyors, and rotary tooling in general industrial automation. Its mechanical interface follows the standard geometry used in the series, which helps it fit common machine layouts. The motor is intended for applications that require repeatable rotary motion and stable response during changing load conditions.

A flange outer span of 91.3 mm provides the mounting face size used for attachment to machine frames or related drive components. During continuous operation, the rotor maintains a rated velocity of 3000 rpm, which suits many feed-axis and rotary handling duties. Rotor position is returned to the drive by a resolver, allowing closed-loop speed and torque regulation even where electrical noise is present. Heat generated in the stator windings is removed through a self-cooling design that relies on free air circulation instead of forced ventilation hardware. The motor also has a backlash and assembly tolerance limited to 10 arcmin, which supports indexing tables and moderate-precision pick-and-place motion.

Cabling exits the housing through an angled connection that swivels, allowing tighter routing inside cabinets or articulated arms. The stator frame incorporates a mounting flange, so the motor can be attached directly to the machine without an adapter plate in many installations. The motor is supplied without a holding brake, so external holding must be provided when the axis must remain fixed at standstill. No oil seal is fitted at the shaft, so the unit is best used where pressurized coolant or lubricant exposure is not expected. The swiveling cable outlet also helps when nearby structures limit the available bend space around the motor body.
