Product Description:

The B-206-B-23 is a permanent-magnet motor produced by Kollmorgen and included in the Kollmorgen Goldline B and BH Motors series. Designed for servo duty, it works with a matched amplifier to regulate shaft motion in automated conveyors, indexers, and robotic joints. By providing controlled rotation from an AC supply, it supports repeatable positioning, stable velocity regulation, and rapid cycle times in factory environments. Its motor type also makes it suitable for applications that require smooth starts, controlled stops, and accurate response to changing load conditions.

The motor draws 5.8 A RMS continuously at rated torque, allowing steady operation without exceeding winding temperature limits. During rapid acceleration or load shocks, it tolerates a peak line current of 19.5 A RMS, supplying additional electromagnetic force for short intervals. A phase inductance of 32 mH slows current rise enough for stable closed-loop control while still supporting responsive operation. The copper winding resistance is 2.32 ohms, which affects heating losses and overall efficiency. At the shaft, the rated speed of 2800 rpm matches the published maximum speed, so the drive can run the motor at full nameplate velocity without derating. A back-EMF constant of 65.1 VRMS/kRPM and a permissible bus voltage of 250 VRMS establish the drive voltage margin needed for normal operation.

Static torque capability is 6.62 N-m at 25 °C and 6.24 N-m at 40 °C, while short-term overload reaches 19.9 N-m for dynamic moves. The motor can deliver mechanical power up to 1.80 kW, which suits mid-frame servo applications such as pumps, spindles, and other continuously regulated axes. Current-to-torque conversion uses a constant of 1.08 N-m/A RMS, which helps relate commanded current to shaft output. A rotor inertia of 0.0002512 kg-m² supports a balance between quick acceleration and rotational stability, and the thermal path to ambient is limited by 0.65 °C/W. The overall mass of 7.6 kg adds mounting stability and supports passive heat dissipation during normal use.
