Product Description:

The 8LSA35.EB030D000-3 is a three-phase synchronous motor built by B&R Automation for the 8LS Synchronous Motors series. Its 8LSA designation and length code 5 indicate a standard build without reinforced bearings. A smooth shaft and mounting flange support direct coupling to precision gear stages or pulleys in packaging, printing, and material-handling equipment where compact servo axes are needed. The design is intended for controlled rotary motion in applications that need accurate speed and position response within a compact footprint.

This model delivers a rated speed of 3000 rpm, giving consistent torque at typical servo bus voltages used on B&R inverters. Position feedback is produced by an inductive EnDat encoder that resolves single-turn and multi-turn angles to 19/12 bits, which supports fine velocity loops and repeatable indexing. The flange dimension of 91.3 mm matches IEC size patterns, allowing the motor to fit common machine frames without adapter plates. Because the unit is supplied without a holding brake, vertical loads must be secured by mechanical clamping or drive-applied torque when power is removed. This arrangement keeps the motor focused on servo motion duties rather than static load holding.

An EnDat protocol revision of 2.1 lets the drive read temperature and electronic nameplate data through the same serial pair, which reduces separate feedback wiring. Thermal management relies on a self-cooling housing with free air circulation, so no external fan or liquid jacket is required. Power and signal leads exit through an angled swivel connector, which eases cable routing in tight enclosures and helps maintain a compact installation. The encoder supports up to 4096 multi-turn revolutions, allowing absolute position recovery after shutdown without batteries. The motor also comes without an oil seal and uses a standard connector interface for straightforward integration with compatible drive hardware.
