8LSA44.EB060D900-3 by B & R Automation

B & R Automation manufactures the 8LSA44.EB060D900-3 for servo applications that need rapid acceleration and precise positioning. The unit belongs to the 8LS Synchronous Motors series and is categorized as a three-phase synchronous motor for closed-loop motion tasks in packaging equipment, indexing stations, and compact assembly cells. In the 8LSA configuration, it is supplied in the standard version without reinforced bearings, which suits lighter radial loads often found in these machines. Its compact format supports machine layouts where installation space and responsive motion are both important. The motor is intended for applications that require repeatable starts, stops, and short positioning moves throughout the duty cycle.

A rated top speed of 6000 rpm sets the maximum operating speed and gives the drive controller a wide usable range. Feedback is handled by Inductive EnDat in version 2.1, a digital system that returns position data with low sensitivity to electrical noise. The single-turn and multi-turn counters provide a combined resolution of 19/12-bit, and the internal gear tracks up to 4096 revs so absolute position remains available after a power cycle. Power and encoder connections are arranged on an angled swivel, and the single connector housing helps simplify cable routing in tight machine spaces. Length code 4 indicates the stack height, while product revision 3 reflects updates to winding insulation and thermal monitoring.

The mounting interface uses a flange diameter of 100 mm, which supports secure alignment on the machine face. Cooling is provided by self-cooling through free air circulation, so no external blower or liquid circuit is required for normal operation. A standard holding brake secures vertical or indexing loads when the drive is disabled, and the shaft is machined with a key for torque transfer to pulleys or gearheads. An integral oil seal helps limit lubricant leakage at the shaft exit and helps keep contaminants away from internal bearing areas. The standardized flange pattern supports straightforward mounting in modular machines.
