Product Description:

B&R Automation manufactures the 8LVB13.B1030F000-0 gear motor as part of the 8LVB Gear Motors series. The device combines a permanent-magnet synchronous motor with planetary gearing and a battery-backed absolute encoder. It is intended for midrange motion axes in packaging, assembly, or material-handling machinery where moderate torque must be delivered at precise speeds. The encoder allows the controller to retain position information after power is removed, supporting controlled restarts without repeating the initial positioning process.

The inductive feedback system supports accurate axis control. It offers a precision of 120 arcsec, allowing the drive to detect fractions of a mechanical degree during interpolation moves. Data exchange with the controller uses the EnDat 2.2 serial protocol, permitting parameter downloads and status uploads over a single cable. An effective 18/16-bit resolution captures the shaft angle within each turn, and a nonvolatile register counts 65,536 revolutions for true multi-turn detection. The counter remains active because the encoder electronics are battery-backed, so no reference run is needed after an emergency stop. The winding draws 1.4 A at rated load but can accept up to 5.2 A when short bursts of additional torque are commanded.

The motor has a nominal speed of 3,000 rpm and supplies 0.32 Nm of torque to the gearbox flange at that operating point. If the shaft is held, stall torque rises to 0.36 Nm, while the current stabilizes near 1.6 A under continuous thermal loading. Four pole pairs in the rotor magnet stack support smooth low-speed operation while keeping torque ripple low. This rotor arrangement helps the connected servo drive maintain stable motion when the axis travels slowly or changes direction. For rapid indexing or overcoming static friction, the system can deliver a peak torque of 1 Nm without exceeding the permissible current limit.
