Product Description:
The 8LVA23.B1030D027-0 is a three-phase synchronous servo motor manufactured by B&R Automation within the 8LVA Three Phase Synchronous Motors series. Designed for electrically driven axes, it converts regulated inverter output into controllable torque for positioning tables, feeder mechanisms, and other motion-focused stations on automated lines. Its design follows the 8LV servo motor profile, allowing machine builders to pair the unit with B&R drives and standardized mounting hardware in space-constrained installations. The synchronous design supports precise speed and position control when the motor is connected to a compatible servo drive.
At a nominal speed of 3000 rpm, the rotor achieves positioning repeatability of ±120 arcsec, supported by the integrated EnDat 2.2 inductive feedback system. This encoder provides 19-bit single-turn and 16-bit multi-turn resolution and tracks 65,536 revolutions after power is removed because the sensor stage is battery-backed. Power conductors and encoder lines exit through separate interfaces, and the built-in double-angle swivel connector simplifies cable routing inside tight enclosures. The motor has a size of 2 and a length of 3, giving it torque and inertia characteristics suited to the middle of the 8LV servo motor range. Separate cabling also limits crosstalk between phase currents and encoder signals, improving the quality of diagnostic data received by the drive.
Thermal losses are removed through self-cooling, so ambient airflow around the housing is sufficient without auxiliary fans or liquid cooling circuits. Mechanical power is delivered through a smooth shaft, allowing the use of clamp-hub couplings that help keep backlash low. The design has no functional safety certification, so external safety monitoring must be added when required by the application. Because the motor has no holding brake, vertical or overhung loads require a separate locking device when power is removed. The shaft is also supplied without an oil seal, so the motor should be isolated from lubricant splashes. External sealing may be necessary when the motor is coupled to a gearbox in an oily environment.
