Product Description:

B&R Automation manufactures the 8LSA34.EB060D000-3, a three-phase synchronous motor in the 8LS Synchronous Motors series, and its internal designation is 8LSA. Designed as a rotary actuator for CNC tables, pick-and-place stations, and other high-dynamics axes, the motor converts servo drive output into controlled torque and speed that a controller can resolve down to a single encoder count. This capability supports short cycle times while maintaining repeatable positioning in automated production lines.

Its rated speed of 6000 rpm allows belt or gear stages to reach high velocities without oversizing. A square flange of 91.3 mm centers the motor on the mounting surface and matches common mounting patterns. Position data are delivered by an Inductive EnDat sensor running protocol version 2.1, and the measuring system exposes 19/12 bits of single-turn and multi-turn resolution to the drive. Wiring is streamlined because power and feedback lines exit through an angled connection that can swivel for strain relief, while a bayonet connector secures the interface. The stator stack carries length code 4, and the standard non-reinforced bearing arrangement fits typical radial loads. Internally wound three-phase coils produce sinusoidal back EMF for smooth torque across the usable speed range.

Heat is removed by a self-cooling housing that relies on free air circulation, so no external fans or liquid circuit are required. A smooth shaft simplifies coupling to clamped hubs or pulleys and avoids keyway stress concentrations. The motor’s multi-turn encoder tracks up to 4096 revs, retaining absolute position after power loss when the axis lacks an external reference switch. Installation is direct because the front face provides a mounting flange with threaded holes, and the angled connector clears adjacent equipment. The design omits an oil seal and a holding brake, which reduces inertia. Hardware revision 3 maintains compatibility with existing B&R drive cables.
