Product Description:

The 8LSA44.EB030D300-3 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. Designed for industrial motion systems, the unit converts electrical input into precisely controlled torque for indexing tables, pick-and-place axes, and continuous-duty conveyors. By pairing with compatible servo drives, it provides a compact rotary actuator that fits directly onto a mounting flange without intermediate transmission stages. Its mechanical envelope follows IEC flange standards, which helps simplify integration into multi-axis platforms.

At a rated speed of 3000 rpm, the motor meets cycle-time targets common in packaging and electronics assembly. Mechanical attachment is through a 100 mm flange that mates to standard housings. Power and signal lines enter from an angled swivel orientation and are terminated by a single connector to reduce cabinet depth. A standard holding brake is fitted to secure loads whenever the drive is disabled. The shaft end is keyed for positive torque transfer, and the 8LSA configuration uses a standard bearing arrangement without a reinforced bearing, which is appropriate for moderate radial forces. Length code 4 indicates the stator stack height, and product revision 3 marks the current production release.

Thermal regulation relies on self-cooling by free circulation, so airflow around the housing is all that is required. For position feedback, the motor carries an Inductive EnDat sensor that operates with protocol version 2.1. The encoder supplies absolute resolution of 19/12 bits for single-turn and multi-turn values and tracks up to 4096 multi-turn revolutions, enabling the controller to recover position after power loss without batteries. Because an oil seal is not present, the front bearing area must be kept clear of process fluids.
