Product Description:
The B-102-A-34 is a brushless servo motor from Kollmorgen and belongs to the Kollmorgen Goldline B and BH Motors series. It is intended for precision positioning or velocity-regulated axes in industrial automation cells. Compact power density and rapid response are important for coordinated motion tasks in industrial machinery.
The motor’s back electromotive force constant is 20.9 Vrms/kRPM, indicating how much voltage the winding generates at a given shaft speed; this value guides drive selection for proper voltage margin. A continuous stall current of 2.4 Arms pairs with the winding design, and when that current is held the motor produces 0.84 N-m of continuous stall torque, enough to hold loads without overheating. Inductance of 30 mH shapes the current rise time, allowing smoother current loops and reducing peak ripple under high-bandwidth control. The mechanical envelope permits operation up to 7500 RPM, so the motor can service high-speed indexing or spindle applications while remaining within its electrical limits. Supplemental figures include a 6.8 Ω DC resistance that establishes typical copper loss and a thermal resistance of 1.3 °C/W for heat flow from stator to ambient.
Total mass is 2.5 kg, which minimizes load on small machine structures, and the rotor is engineered with 0.0000309 kg·m² of inertia to support fast accelerations. A four-pole design with 4 magnetic poles balances torque ripple against speed capability. For transient events, the drive may supply a peak current of 7.2 Arms, allowing the motor to reach a peak stall torque of 2.41 N-m for short intervals. Thermal time constant is 10 minutes, giving the system a predictable warm-up profile under cyclic duty. The shaft is supplied with no rear extension and no front seal, and power enters through a bayonet connector with mating plugs for quick installation.
