8LSA35.EB030D000-0 by B & R Automation

B & R Automation designs the 8LSA35.EB030D000-0 for the 8LS Synchronous Motors series. This three-phase synchronous motor mounts directly to a machine flange and is intended for position-controlled or speed-controlled axes in automated machinery. With an integrated encoder interface, the motor reports rotor angle to the controller, allowing closed-loop motion without external feedback accessories. That arrangement helps keep the installation compact and reduces the number of separate components around the axis.

The motor's rated shaft velocity is 3000 rpm, supporting medium-speed conveyors and packaging spindles. The flange has a 91.3 mm face dimension that matches the machine frame and sets the bolt pattern at the mounting surface. Rotor position is monitored by an Inductive EnDat system that is less sensitive to contamination than optical devices. The encoder electronics use version 2.1, which supports bidirectional parameter transfer and online diagnostics. Self-cooling through free air circulation removes heat without external blowers, and the connector housing accepts a swivel cable plug that helps cable routing in tight spaces. Because the motor uses standard bearings, axial and radial loading must stay within normal limits during operation.

The encoder provides 19/12 bits of single-turn and multi-turn data, giving absolute position values without interpolation. Mechanical rotation counting continues for up to 4096 revs, so the controller can retain turn information after a power cycle. The motor uses a smooth shaft for coupling to compliant hubs, which avoids keyway stress concentrations. Wiring exits through an angled swivel connector, reducing vertical clearance in compact enclosures. The lack of a holding brake and oil seal supports the motor's self-cooling layout by reducing inertia and friction during rapid speed changes and repeated start-stop movement.
