Product Description:

The B-102-A-22 is a brushless servo motor manufactured by Kollmorgen within the Kollmorgen Goldline B and BH Motors series. It is built for industrial automation axes that require compact dimensions and high rotational speed. The motor includes an integrated resolver so the paired drive amplifier can regulate velocity or torque as commanded. In automated machinery, it converts electrical input into mechanical rotation for positioning, feeding, and light-duty spindle tasks.

During continuous operation, the drive electronics supply a line current of 2.4 A RMS, producing a continuous stall torque of 0.84 N·m. Copper losses are limited by 6.8 ohms of DC resistance, while the phase inductance of 30 mH helps filter switching ripple from the amplifier. The rotor reaches a rated mechanical speed of 7500 rpm, and that speed with the torque curve yields an output of 0.54 kW. Bayonet connectors without preinstalled plugs simplify cable routing, and the standard metric face supports direct mounting on IEC frames. The assembly weighs 2.5 kg, which helps limit moving mass in multi-axis gantries where lower mass can support quicker axis response.

For short acceleration bursts, the amplifier may deliver a peak line current of 7.2 A RMS, allowing the magnetic circuit to develop up to 2.41 N·m of torque. Dynamic response benefits from the 0.000031 kg·m² rotor inertia, and position feedback is supplied by a frameless resolver mounted directly on the shaft. The generated back EMF is 20.9 VRMS/krpm, which affects the required DC bus voltage during operation. An IP65 housing blocks dust and low-pressure water jets, and the design omits a rear shaft extension to reduce external seal points. This arrangement also leaves the motor with a simpler shaft layout for installations that do not need a secondary mechanical takeoff.
