8LSA53.DB022S900-3 by B & R Automation

The 8LSA53.DB022S900-3 synchronous motor is produced by B&R Automation within the 8LS Synchronous Motors series. As a three-phase synchronous unit, it supplies controlled torque and velocity for positioning axes and continuous-duty drives in industrial automation cells. The designation 8LSA marks this variant as a standard build without reinforced bearings, and the part attaches to machinery through an integral flange to couple directly with gearboxes or load shafts. This arrangement supports accurate rotary motion where compact installation and stable mechanical alignment are required.

Power and feedback are routed through a single-cable solution that terminates in a shielded connector, simplifying wiring in distributed control cabinets. Inside the housing, an inductive EnDat encoder using version 2.2 provides absolute position data at 19/12 bits resolution and supports electronic nameplate functions. The encoder is tuned to the motor's rated speed of 2200 rpm, allowing closed-loop regulation without overspeed alarms. Mechanical integration is aided by a mounting flange whose outside dimension is 142 mm, and the keyed shaft ensures positive torque transfer. Length code 3 keeps the overall body compact while still accommodating the winding stack needed for the rated speed.

Thermal management relies on self-cooling by free circulation, so no auxiliary fan or coolant lines are required. A standard holding brake is integrated to secure the load during power-off states, and an oil seal helps prevent lubricant ingress into the stator cavity. The encoder's 4096-revolution multi-turn range keeps absolute position valid through extended rotation, supporting machines that re-index after shutdown. Electronic assemblies correspond to product revision 3, and the hybrid cable concept leaves service ports accessible in tight machine spaces.
