8LSA46.S1060C200-0 by B & R Automation

The 8LSA46.S1060C200-0 is a three-phase synchronous motor produced by B & R Automation and assigned to the 8LS Synchronous Motors series. Within an automated line, this motor converts regulated drive currents into precise rotary motion for axes that require high speed and encoder feedback. The 8LSA designation marks it as the standard configuration that omits a reinforced bearing, making it suitable for general-purpose positioning tasks where standard radial loads are expected.

At a rated speed of 6000 rpm, the rotor can sustain continuous operation without derating, giving the application a clear speed ceiling when selecting gear ratios or direct-drive couplings. Heat is removed through a self-cooling design that relies on free air circulation, so no external blower or liquid circuit is needed. The motor mounts against machinery through a flange that measures 100 mm, providing a repeatable reference surface and compatibility with common IEC housings. Position feedback is supplied by an optical EnDat encoder, allowing absolute position transfer over a single cable and reducing wiring inside the cable tray.

The integrated standard holding brake secures the axis whenever power is removed, which can eliminate the need for external clamps on vertical loads. Power and feedback lines exit through a straight top connector, which can simplify cable routing in compact cabinets; the mating plug is supplied by B & R. The encoder operates with EnDat version 2.2, delivers 25/12 bit single- and multi-turn resolution, and tracks position across Multi-turn 4096 revs without battery support. A length code 6 stator housing balances torque density against envelope size, while the smooth shaft end eases coupling to precision hubs. No oil seal is fitted, so the application should ensure a clean environment around the shaft opening.
