Product Description:
The B-406-D-23-630 is a brushless servo motor manufactured by Kollmorgen and supplied through the Kollmorgen Goldline B and BH Motors series. It is intended for closed-loop motion axes in industrial automation, where repeatable torque delivery and precise velocity control are required for packaging lines, pick-and-place stations, and general material handling applications. This makes the motor suitable for automation tasks that require accurate starts, stops, and speed changes throughout repeated production cycles. Its four-pole rotor architecture helps support smooth low-speed operation with stable motion at controlled speeds.
The motor has a back electromotive force constant of 74.9 Vrms/kRPM, which links shaft speed to generated voltage. Its torque constant is 1.24 N-m/Arms, showing how much torque is produced for each ampere supplied by the controller. At its rated operating point, the machine delivers 9.55 N-m at a mechanical output power of 2500 W. For steady load holding, the continuous stall torque reaches 18.6 N-m, while short-term overloads are handled by a peak stall torque of 52.9 N-m. Electrical losses are characterized by 0.75 Ω line-to-line resistance, and current ripple is moderated by 20 mH winding inductance.
A continuous stall current of 15 Arms sets the steady-state electrical limit, while a peak stall current of 45 Arms supports rapid acceleration and short bursts of higher demand. The rotor provides a moment of inertia of 0.000929 kg-m², which helps the axis respond quickly during reversals and speed changes. Heat produced in the windings passes through a thermal resistance of 0.35 °C/W, and the thermal time constant of 28 min shows that the motor warms gradually during extended duty. The 15.9 kg mass adds thermal buffering and helps provide a rigid mounting base.
