8LSA53.DB030S800-3 by B & R Automation

The 8LSA53.DB030S800-3 is a three-phase synchronous motor manufactured by B&R Automation as part of the 8LS Synchronous Motors series. It carries the 8LSA designation with length code 3 and product revision 3. The unit serves as a compact drive element for industrial automation axes where regulated torque and velocity are required to coordinate motion between machine stations. Its compact housing suits servo applications in packaging, indexing, and material-handling equipment where installation space is limited.

This model is engineered for continuous operation at 3000 rpm, a speed class that suits common inverter outputs used on packaging and material-handling lines. Rotor position is reported through an Inductive EnDat 2.2 encoder that provides 19/12-bit single-turn and multi-turn feedback across a tracking range of 4096 revolutions. This feedback allows the connected drive to track shaft position and speed during closed-loop operation. Heat produced by copper losses is removed through self-cooling with free air circulation, so no external blower or liquid jacket is required. The motor uses a standard bearing set without reinforcement, and an internal oil seal helps block lubricant migration toward the stator windings. A smooth shaft end simplifies coupling to backlash-free hubs, and the mounting flange mates directly to gearboxes or machine plates.

A standard holding brake is integrated to secure vertical or indexing loads when the drive is disabled. Power, brake, and encoder signals share a single-cable solution that terminates in a molded connector, which helps reduce cabinet penetrations and cable carrier bulk. The mounting flange has a 142 mm center dimension, providing a rigid interface for direct attachment to machine plates or gearboxes. As a three-phase synchronous motor, the unit works with servo systems that use EnDat feedback and hybrid cable routing.
