Product Description:

B&R Automation supplies the 8LSA57.D0030D000-1 as part of its 8LS Synchronous Motors series. The unit is a three-phase servo motor used to generate precise rotary motion for positioning axes and continuous-duty drives in automated equipment. It is intended for applications that need accurate speed control and repeatable positioning during continuous industrial operation. Within the 8LSA designation, it follows the standard configuration without reinforced bearings, so mechanical loads must remain within the bearing limits. The motor is built for flange installation, and its absence of a holding brake means any static shaft locking must be handled by the machine rather than by the motor itself.

The motor reaches a rated speed of 3000 rpm, allowing direct coupling to gear stages or application shafts that require moderate to high rotational velocity. Power and feedback conductors exit through an angled swivel connector, which helps reduce cable bend stress in cramped cabinets. Thermal management relies on self-cooling by free circulation, so unobstructed airflow around the housing must be maintained. Position feedback is provided by an optical EnDat encoder that conforms to version 2.2, enabling digital diagnostics and automatic parameter transfer to the drive controller. The encoder provides a resolution of 25/0 bits, which indicates single-turn feedback without multi-turn counting, and the connector-based cabling fits the length code 7 mechanical envelope.

The mounting flange measures 142 mm, which matches standardized gearbox or frame adapters. A smooth shaft end simplifies coupling to clamp hubs or keyed bushings while minimizing fretting at low torque levels. The motor uses a three-phase synchronous design, so torque remains proportional to current and phase displacement for precision indexing. Because the unit does not include an oil seal, the front bearing should be protected from splash. Connection hardware uses a keyed circular connector for secure attachment without affecting the mounting flange.
