Product Description:
B & R Automation manufactures the 8LVB23.R0025S1FW00 gear motor as part of its 8LVB Gear Motors series. The product combines a permanent-magnet synchronous motor section with a factory-fitted planetary gearbox, so speed reduction and torque multiplication occur in one housing. Intended for industrial automation, the unit provides a direct, feedback-ready mechanical interface for assembly lines, packaging stations, and semiconductor handling equipment where precise velocity control and compact installation dimensions are important. Because the gearbox is supplied as part of the assembly, shaft alignment between the motor and reduction stages is fixed at the factory, which helps maintain consistent motion behavior.
The drive section delivers a nominal shaft speed of 3000 rpm while producing 1.3 Nm of continuous torque after the gearbox reduction. To sustain this output, the winding draws 5.8 A of continuous phase current, and the control amplifier may supply up to 20.7 A during short load peaks. With a torque constant of 0.23 Nm/A, additional current raises the available electromagnetic torque in proportion before the gearbox multiplies it. The integrated resolver reports rotor position to the controller, and a built-in double-angle connector routes both power and feedback conductors without external junction boxes. A back electromotive force value of 13.61 V per 1000 rpm corresponds to the voltage needed for rated speed and matches common 24 to 60 V servo inverters.
Dynamic behavior is influenced by an electrical time constant of 2.41 ms. The stator inductance is 2 mH, and the stator resistance is 0.83 Ω, which affect current rise, copper loss, and amplifier response when the axis accelerates or settles into position. These values are important when the drive is tuned for rapid starts, stops, and load changes in compact automation axes. Resolver feedback is specified to within 10 angular minutes, giving the motion controller enough accuracy for smooth interpolation at the gearbox output.
