Product Description:
The 8LVA23.B8A95S004-0 is a three-phase synchronous servo motor supplied by B & R Automation within the 8LVA Three Phase Synchronous Motors series. It belongs to the manufacturer’s 8LV Servo Motor platform and is sized for axes that require moderate torque and precise positioning. The motor is intended for direct integration into machine tools, packaging stations, and material-handling gantries where its compact construction and single-cable installation simplify equipment layout.
This model delivers a nominal shaft speed of 950 rpm and dissipates heat through a self-cooling housing, eliminating the need for external blowers. Power conductors and encoder lines share one connector because the unit uses a hybrid single-cable solution. The angled connector can swivel to reduce cable strain and accommodate different routing directions. Rotor position is reported by an EnDat 2.2 inductive feedback system that supports online diagnostics and digital calibration. Positional accuracy reaches ±120 arcsec, allowing consistent repeatability during indexing tasks. The motor operates without a holding brake, so the drive must provide static torque when load drift must be prevented. Its encoder does not require a backup battery and provides position data within one mechanical revolution.
The unit supports functional safety, enabling safe-stop and speed-limited functions when paired with suitable drives and controls. Mechanical output is transmitted through a smooth shaft, which accommodates backlash-free clamp couplings on gearheads or pulleys. Encoder granularity uses a 19/0-bit structure, providing 19-bit single-turn resolution without multi-turn counting. The stator stack has motor length 3, providing greater magnetic volume than shorter configurations while retaining a size 2 frame. The motor does not have an oil seal and should not be exposed to environments containing pressurized lubricant. Its mounting area should remain protected from fluids that could reach the shaft opening, and the connected machine should provide suitable guarding where contamination is possible.
