8LVA23.B1030D027-0 by B & R Automation

The 8LVA23.B1030D027-0 is a three-phase synchronous motor produced by B&R Automation within the 8LVA Three Phase Synchronous Motors series. It operates as a servo element in automated machinery, converting controlled electrical energy into repeatable rotary motion for indexing tables, gantry axes, and conveyor sections where exact positioning is required. This role makes the motor suitable for applications that depend on stable speed control, accurate stopping behavior, and consistent response during repeated motion cycles.

Inside the feedback loop, an inductive encoder delivers a positional accuracy of ±120 arcsec and provides 19/16 bits of single-turn and multi-turn resolution. The rotor maintains a nominal speed of 3000 rpm, which suits common cycle rates in packaging and electronics assembly equipment. Thermal control is handled by a self-cooling housing, so no external fan is required. Position and diagnostic data are exchanged through the bidirectional EnDat 2.2 Inductive interface, and the internal battery preserves the encoder’s absolute position value when power is removed. Length code 3 and size 2 indicate the motor dimensions used in this version. The unit does not include functional safety circuitry, a holding brake, or an oil seal, which helps reduce rotating mass.

For axes that travel through many turns, the absolute counter records up to 65536 revolutions without losing the stored position reference. Wiring is simplified by a built-in double angular connector that can swivel to suit cabinet entry angles and compact installation spaces. Electromagnetic compatibility is improved through separate encoder and power cabling, which helps reduce interference between feedback signals and motor current conductors. A smooth shaft supports backlash-free coupling with clamp, serrated, or shrink-disk hubs. This arrangement supports clean cable routing and straightforward integration in distributed motion systems.
