Product Description:

The B-206-A-39-010 is a brushless servo motor produced by Kollmorgen within the Goldline B and BH Motors series. The unit is intended for closed-loop industrial automation where accurate position and velocity control are required for packaging gantries, electronic assembly axes, and material handling modules. The motor integrates with Kollmorgen drives through standard resolver feedback, allowing smooth torque production across its operating range. Its compact frame and four-pole rotor design help maintain high torque density while keeping mass and inertia manageable in multi-axis machines.

At continuous load, the motor draws 3.0 A RMS, and this steady-state current supports a rated mechanical output of 0.97 kW. When driven at the nominal shaft speed of 1400 RPM, the motor remains within its thermal limits while supplying uniform torque. For transient move profiles, the rotor can deliver up to 20.5 N·m of peak torque, giving strong acceleration capability before saturation. The phase inductance of 130 mH slows current rise enough to protect power electronics while still supporting responsive current-loop control in servo applications. The 8.82 Ω DC resistance contributes to copper losses at the specified current level.

Thermal management is supported by a housing-to-ambient thermal resistance of 0.64 °C/W, so many applications can rely on convection airflow to control winding temperature. Heat buildup is gradual because the motor has a thermal time constant of 22 min, which allows short overload periods without immediate derating. Electrically, the stator is insulated for supply buses up to 250 VRMS, and the torque constant of 2.15 N·m/A RMS helps determine the current required for a given torque demand. The motor also has a back EMF constant of 130 VRMS/kRPM and a stall torque of 6.90 N·m at 25 °C.
