8LVA23.B1030D27-0 by B & R Automation

The synchronous servo motor 8LVA23.B1030D27-0 is produced by B&R Automation as part of the 8LVA Three Phase Synchronous Motors series. Within an automation cell, it provides closed-loop rotary positioning for axes that need repeatable motion, and its smooth shaft end couples directly to gears or pulleys without keyways. This type of motor is suited for positioning axes in packaging, handling, and other automated equipment that requires repeatable rotation. The motor belongs to the 8LV Servo Motor product family and combines motor size 2 with length code 3 in a compact housing.

The motor can reach a nominal speed of 3000 rpm, allowing standard transmission ratios to achieve common machine velocities. A holding brake rated at 2.2 Nm keeps the load stationary when power is removed, while overall positioning error is limited to ±120 arcsec. Position data come from an EnDat 2.2 inductive encoder that provides 19/16 bits of single-turn and multi-turn resolution, and the encoder and power leads exit through separate interfaces to help reduce crosstalk. That arrangement supports cleaner signal transmission where motor and encoder cables must turn sharply near the machine frame. The swivel connection lets cabling be angled to suit tight panel spaces, and functional safety certification is not provided, so any safety-related stop functions must be implemented externally.

Absolute position over the full mechanical range is retained for up to 65536 revolutions. The self-cooling motor body relies on natural convection rather than forced airflow to dissipate heat. The housing uses a built-in double angular connector, and the design is battery-backed to preserve multi-turn data during power outages. Absolute feedback helps the axis retain position information after power interruptions and reduces the need for reference moves at startup. A separate encoder cable helps reduce interference from the power conductors, and there is no oil seal at the shaft exit.
