Product Description:
The 8LVB22.R0030F300-0 is a gear-integrated servo motor produced by B&R Automation within the 8LVB Gear Motors series. It couples an internal permanent-magnet synchronous motor to a predefined gearbox stage so that machine builders can obtain repeatable torque at set speeds without external coupling hardware. In automated assembly lines, packaging systems, and light material-handling axes, the unit converts DC bus energy supplied by a drive module into accurately regulated shaft motion, simplifying installation and reducing cabinet wiring.
The motor delivers a nominal speed of 3000 rpm, matching applications that require rapid yet stable rotation. At this operating point, it produces 0.65 Nm of continuous torque while drawing a nominal current of 2.9 A. Current peaks up to 10.3 A can be tolerated during acceleration, supported by a stator inductance of 4.1 mH and a winding resistance of 2 Ω. These electrical values yield a time constant of 2.05 ms, allowing swift current transients without excessive ripple. The motor contains four pole pairs, so the internal resolver can report mechanical position at high resolution even at maximum speed. A torque constant of 0.23 Nm/A relates phase current to developed torque, and a voltage constant of 13.61 V/1000 rpm indicates the back electromotive force that the inverter must overcome when regulating velocity.
When the shaft is held stationary, the winding produces 0.68 Nm of stall torque at a stall current of 3 A. Short overloads can increase output to 2 Nm without demagnetizing the rotor. The embedded resolver supplies absolute position feedback to the drive, allowing closed-loop control to limit overshoot and cogging. Heat generated by copper loss moves slowly to the housing, as indicated by a thermal time constant of 35 minutes. This thermal response permits intermittent operation above the nominal load without a rapid increase in motor temperature.
