Product Description:

The 8LVB23.B9010S4FW00 gear motor is produced by B&R Automation as part of the 8LVB Gear Motors series. It combines a permanently excited servo motor with a compact planetary gearbox, supplying precise rotary motion to indexing stations, conveyors, and light assembly modules. In an automation system, the device converts drive current from the controller into position-controlled shaft motion while the gearbox multiplies torque. This arrangement supports space-saving installation where a comparable direct-drive package would be too large.

Mechanical output is matched to machine inertia through a gear ratio of 10 implemented in one gear stage. Combined transmission and motor losses remain low, resulting in an efficiency of 96% at rated load. The device supplies a nominal torque of 1.3 Nm at 3000 rpm and can momentarily reach 4 Nm during acceleration. Motion feedback comes from a high-resolution encoder with 19/12-bit resolution, which stores absolute position over 4,096 turns without requiring a homing cycle. Positioning repeatability is supported by a maximum backlash of 12 arcmin, keeping errors within acceptable limits for pick-and-place equipment. Drive current response is influenced by a stator inductance of 2 mH, while the winding resistance of 0.83 Ω determines steady-state copper loss.

For holding an axis at rest, the motor integrates a brake rated at 2.2 Nm that clamps the shaft when power is removed. The winding has a thermal time constant of 38 minutes, indicating how quickly its temperature responds to sustained operating losses. The back electromotive force has a slope of 13.61 V/1000 rpm, which helps the drive scale voltage commands across the operating speed range. A torque constant of 0.23 Nm/A converts current into proportional motor torque for closed-loop control. The moderate thermal response allows generated heat to accumulate gradually during continuous operation without requiring additional cooling hardware.
