Product Description:

The 8LVB22.R0032S5FW00 is an integrated servo gear motor supplied by B&R Automation within the 8LVB Gear Motors series. The unit couples a permanent-magnet synchronous motor with a planetary gearbox and is intended for positioning axes, conveyors, and pick-and-place modules where compact drive solutions simplify machine layouts in industrial automation. It combines the motor and transmission in one housing, reducing cabling and alignment effort compared with separate components. This integrated arrangement also reduces the number of mounting interfaces required between the motor and driven equipment.

Two planetary gear stages provide a gear ratio of 32. The motor has a nominal torque of 0.65 Nm, while the gearbox can deliver an output torque of 44 Nm. At a motor speed of 3000 rpm, the reduction ratio provides a shaft speed suited for indexing tables and belt drives while keeping the drive dimensions compact. Positional accuracy remains consistent because the maximum backlash is limited to 12 arcmin. The gearbox withstands a radial load of 340 N and an axial load of 450 N over 30,000 operating hours, accommodating typical cam or pulley side loads. With a torque constant of 0.23 Nm/A, motor torque scales predictably with commanded current, allowing the controller to regulate force accurately.

Electrical performance includes a nominal phase current of 2.9 A and a stator inductance of 4.1 mH, which affect current rise time and servo tuning. An electrical time constant of 2.05 ms indicates that torque can be established quickly after a command change. The stator resistance is 2 Ω, so copper losses remain moderate during continuous operation. The voltage constant of 13.61 V/1000 rpm establishes the back electromotive force that the drive must overcome as speed increases. A holding brake rated at 2.2 Nm secures vertical axes when power is removed. The dual gear stages add minimal inertia to the servo loop, helping the drive maintain responsive motion during acceleration and deceleration.
