8LSA44.D1022D400-0
The 8LSA44.D1022D400-0 is a three-phase synchronous motor produced by B&R Automation and assigned to the 8LS Synchronous Motors series. Acting as a compact servo prime mover, it converts regulated drive output into repeatable rotary motion for tasks such as indexing conveyors, camming packaging axes, and coordinated robot joints in automated production environments. The motor’s electrical characteristics are matched to compatible AC servo amplifiers for straightforward integration into closed-loop motion systems.
Its mechanical interface starts with a mounting flange that measures 100 mm across and is paired with length code 4 to establish the overall stator stack. The shaft is a smooth shaft, so couplings or belt pulleys can slide on without key machining. Speed capability tops out at 2200 rpm, giving a balance between velocity and continuous torque for mid-range motion duties. Power and feedback leads exit through an angled swivel outlet, and a single connector carries both phases and encoder lines, which helps simplify cable routing. Thermal management relies on self-cooling with free air circulation, eliminating the need for external blowers. The configuration is standard without reinforced bearings, and because no oil seal is present, the surrounding environment must be free of liquid contaminants.
Position information is delivered by an optical EnDat feedback unit that uses EnDat 2.2 for fully digital transmission. The encoder supplies 25/12 bits of single-turn and multi-turn data, while an internal counter tracks up to 4096 revolutions, enabling absolute position reporting even after power loss. For load retention during shutdown or faults, a heavy-duty holding brake clamps the rotor. The 8LSA designation differentiates this motor variant within the series and assists with selecting compatible drive parameters in B&R drive setups.
