8LSA45.EA060D300-0 by B & R Automation

B&R Automation's 8LSA45.EA060D300-0 belongs to the 8LS Synchronous Motors series and is used as a rotary axis drive in automated machinery where precise speed control is required. Within the 8LSA designation, this model is supplied in a standard configuration without reinforced bearings, and it connects to machine structures through a 100 mm flange interface. By operating with servo drives and PLC-controlled motion systems, the motor provides regulated torque for positioning tasks on packaging lines, pick-and-place gantries, and indexing tables.

The unit is a three-phase synchronous design that reaches a rated speed of 6000 rpm, allowing direct coupling to fast spindle or conveyor loads. Position feedback is generated by an inductive EnDat encoder that communicates through EnDat version 2.1, and its measuring electronics are housed inside the stator to help protect signal quality. Thermal management relies on self-cooling with free air circulation, so no external blower or liquid loop is needed during continuous duty. Mechanical attachment is made on the mounting flange, whose pilot diameter is 100 mm, and the motor uses body length code 5. The standard build omits reinforced bearings but retains a shaft end with a key for slip-free power transfer. Electrical terminations are made through a single connector, which simplifies cabinet wiring.

Cabling can be routed cleanly because the connector exits in an angled swivel direction, reducing bend stress in tight enclosures. A standard holding brake keeps the load stationary when the drive is disabled, which is useful on vertical axes. The encoder offers a resolution of 19/0 bits for single-turn and multi-turn data and supports a single-turn measuring range that suits indexing applications. An oil seal is not present, so the motor should be installed where excessive coolant or oil splash is avoided. The mounting flange provides the required face-mount points to secure the stator without additional brackets.
