8LSA57.D0030D000-3 by B & R Automation

The 8LSA57.D0030D000-3 is a three-phase synchronous servo motor produced by B&R Automation for the 8LS Synchronous Motors series. It is intended for positioning and velocity control tasks in automated machinery where compact mounting and encoder feedback are required. This type of motor is typically paired with a servo drive for closed-loop motion control on indexing, transfer, and handling axes. The 8LSA configuration code indicates a standard build without reinforced bearings, and revision 3 identifies the assigned product version for this model.

The motor delivers a rated speed of 3000 rpm, which suits common drive controller outputs used in packaging lines and pick-and-place modules. Heat is removed by a self-cooling method that relies on free air circulation, so no external blower is required. Position data are generated by an optical EnDat encoder, and protocol version 2.2 supports bidirectional transmission of both position and diagnostic data over a single cable. Electrical power and feedback pass through a swivel connector that is angled relative to the stator housing, which helps keep cabling clear of linear axes and other nearby machine elements. The unit is supplied without a holding brake, so any static load retention must be provided by the drive or by external mechanical components. A mounting flange supports direct attachment to the machine, and length code 7 identifies the stator stack depth used for this housing.

Cable management is improved by the angled connection orientation, which reduces bend stress at the cable exit point during installation and operation. The square flange measures 142 mm, providing a standardized interface for machine frames or gearbox adapters. A smooth shaft end is provided for couplings that use friction or shrink-fit joints, and the absence of an oil seal limits use to clean environments without pressurized lubricant. The EnDat sensor provides a 25/0 bit single/multi-turn resolution, while the motor is configured for single-turn feedback in applications that return to home after each cycle.
