Product Description:

The B-102-A-24 is a brushless servomotor manufactured by Kollmorgen within the Kollmorgen Goldline B and BH Motors series. Supplied with three-phase power from a servo amplifier, the unit converts controlled electrical input into rotary motion for precision axes in packaging, semiconductor handling, and light machining equipment. Its purpose in industrial automation is to maintain accurate speed and torque across repeated duty cycles where rapid indexing and repeatable positioning are required.

At a rated speed of 7500 RPM, the motor delivers its continuous mechanical output of 0.54 kW while drawing a phase current of 2.4 A RMS. For short bursts of acceleration, the permissible current rises to 7.2 A RMS, producing a peak torque of 2.41 N-m. The stall torque at 40 °C is 0.84 N-m, indicating the static load the motor can hold without motion. A DC resistance of 6.80 Ω limits copper loss, and the absence of a front shaft seal minimizes friction during high-speed operation. These values describe the motor's continuous operating range and its short-term overload capability during repeated servo duty in precision motion systems.

The winding inductance is 30.0 mH, providing an electrical time constant that smooths phase current transitions and assists the servo drive's current loop. A rotor inertia of 0.000031 kg-m² enables rapid speed changes with modest acceleration torque demands. The electromagnetic coupling uses a torque constant of 0.35 N-m/A RMS and a back-EMF constant of 20.9 VRMS/kRPM, which the drive uses to calculate voltage commands during vector control. Connection to the cable set is through bayonet connectors, the mounting face follows a standard metric layout, and there is no rear shaft extension. With a mass of 2.5 kg, the motor can be integrated on lightweight axes without exceeding typical load limits.
