8LVA23.B8A95S004-0 by B & R Automation

The 8LVA23.B8A95S004-0 is a three-phase synchronous servo motor manufactured by B&R Automation in the 8LVA Three Phase Synchronous Motors series. Within the 8LV Servo Motor family, this model is intended for positioning axes and gantry modules in industrial automation that depend on repeatable motion. It converts electrical power into regulated rotary motion and returns encoder data to the controller so speed and position can be regulated during operation.

The motor reaches a nominal speed of 950 rpm, which suits conveyor and indexing duties that need steady base speed rather than high-end spindle velocity. Feedback is supplied by an EnDat 2.2 inductive encoder with a resolution of 19/0 bits for single-turn and multi-turn feedback, and the reported positioning accuracy is ±120 arcsec. Power conductors and encoder lines are combined in a single-cable solution that exits through an angled swivel connector, which reduces cable bulk and supports flexible routing. The encoder provides single-turn information only, and the motor has no holding brake, so the shaft must be restrained externally when power is removed. Because the motor also lacks an oil seal, it is better suited for clean, dry operating areas.

The motor has size 2 and a proportionate motor length 3, which helps it fit dense multi-axis layouts without requiring a large installation envelope. Cooling is handled by self-cooling, so no external fan or liquid circuit is needed. The compact housing leaves room for adjacent axes, and the passive cooling arrangement avoids separate airflow hardware around the motor body. The output uses a smooth shaft, making it suitable for couplings, belt pulleys, and gearheads that do not require a keyed shaft. Integrated functional safety features, including safe torque off, support installations that need the drive axis to be shut down through built-in safety functions.
