Product Description:

The B-102-A-14 is a brushless servo motor produced by Kollmorgen and placed in the Kollmorgen Goldline B and BH Motors series. Designed for tightly controlled motion axes, the unit converts electrical power from a matched drive into continuous rotary torque for positioning, velocity regulation, and coordinated moves in industrial automation cells. Its frameless resolver feedback integrates directly with Kollmorgen drives so motion controllers can close the loop on position and speed without external encoders, making the motor suitable for packaging lines, pick-and-place gantries, and light machine tools.

At a rated speed of 7500 RPM, the motor can sustain a continuous output of 0.54 kW while delivering a steady 0.84 N·m of stall torque at 40 °C. That torque is produced with a phase current of 2.4 A RMS, which helps indicate the motor’s thermal load during continuous operation. The back electromotive force constant is 20.9 VRMS/kRPM, which indicates the voltage that the drive must overcome per thousand revolutions. A winding inductance of 30.0 mH shapes current rise time and influences tuning bandwidth so command signals remain stable under servo control. A line-to-line resistance of 6.80 Ω contributes to copper loss and thermal dissipation calculations.

Transient demands are handled by a peak torque of 2.41 N·m, delivered when the drive supplies up to 7.2 A RMS for short intervals. Because torque rises linearly with current at low speed, the stall sensitivity of 0.35 N·m/A RMS helps estimate available load acceleration before motion begins. The rotor’s low inertia of 0.0000309 kg·m² minimizes start-stop lag, permitting rapid indexing in multi-cycle applications. Flying leads measuring at least 457 mm simplify integration into cable tracks, and a maximum line-to-line voltage rating of 250 VRMS helps keep insulation stress within safe limits when the motor is driven from high-bus servo inverters. The 2.5 kg mass supports compact mounting on small mechanical frames.
