8LSA44.DA045S200-3 by B & R Automation

The 8LSA44.DA045S200-3 is a three-phase synchronous motor produced by B&R Automation and supplied as part of the 8LS Synchronous Motors series. Within an industrial automation cell, the unit converts three-phase electrical power into controlled mechanical rotation for closed-loop axis motion. It is suited for positioning tables, gantries, and packaging axes that rely on precise speed control, repeatable motion, and rapid start-stop cycles.

The motor reaches a rated speed of 4500 rpm, giving the drive a usable velocity range for medium-to-high-speed servo tasks. A flange dimension of 100 mm sets the mounting pattern and supports installation on compatible machine interfaces. Position feedback is provided by an Inductive EnDat 2.2 encoder, so absolute position data is transmitted digitally to the drive with strong noise immunity. Power conductors and encoder lines share one connector through the single-cable solution, which reduces wiring bulk and simplifies cable routing through drag chains. Thermal management is handled by self-cooling with free circulation, so the housing dissipates heat without external blowers or liquid circuits.

For load retention during power-off states, the motor includes a standard holding brake, which helps keep vertical or indexing axes in place. A smooth shaft eases coupling to backlash-free clamps or timing pulleys while avoiding keyway stress concentrations. The integral mounting flange supports direct attachment to machine frames, aligning the stator bore without additional adapter plates. The motor uses a three-phase synchronous winding arrangement for consistent torque production through each electrical cycle. The encoder provides 19-bit single-turn resolution with no multi-turn count, which supports fine position interpolation in servo loops. Revision 3 indicates the current revision level, and the design omits an oil seal for dry mounting environments.
