8LSA34.EA060D100-3 by B & R Automation

The 8LSA34.EA060D100-3 motor is produced by B&R Automation and belongs to the 8LS Synchronous Motors series. This three-phase synchronous unit is intended for use as a servo axis in industrial automation, where precise torque and repeatable speed are needed for packaging machines, material-handling gantries, and small machining centers. It uses digital feedback and inverter-supplied current to convert electrical power into controlled rotational motion for the connected load. That closed-loop arrangement supports consistent positioning during repeated starts, stops, and speed changes.

The motor has a rated speed of 6000 rpm, allowing rapid positioning cycles without exceeding its thermal limits. The square mounting face measures 91.3 mm, so the motor pairs with standardized mechanical frames. Heat is dissipated through self-cooling with free circulation, so the aluminum housing fins remove heat without an external fan. Position feedback is supplied by an EnDat 2.1 inductive encoder with a resolution listed as 19/0 for single-turn and multi-turn data. The encoder is factory matched to the stator length indicated by length code 4. The motor is provided without a holding brake and without an oil seal, which keeps the package compact for dynamic installations.

The power and feedback conductors exit through an angled swivel interface, which simplifies cable routing in compact cabinets and tight machine spaces. The motor comes with no reinforced bearing, so it uses the standard bearing arrangement for this build. Mechanical coupling is achieved by a shaft end with a key, which supports secure torque transmission to the driven element. This description refers to product revision 3, and the motor attaches directly to machinery through the provided mounting flange without additional adapter plates.
