Product Description:
The BH-826-A-43-B3 is a brushless servo motor produced by Kollmorgen within the Goldline B and BH Motors series. It converts three-phase electrical power into controlled rotary motion. The motor supports positioning tables, gantries, and other automation axes that demand high dynamic accuracy and repeatable torque delivery.
Under load at zero speed, the motor can develop a continuous stall torque of 93.5 N-m while drawing 21.8 Arms of phase current. This continuous operating level remains within the thermal dissipation capacity of the winding and frame. During rapid acceleration, the motor tolerates peak conditions up to 323 N-m and 79.2 Arms, providing a short-term reserve for indexing movements or impact loads before magnetic saturation occurs. The electromagnetic conversion efficiency is represented by a torque constant of 4.29 N-m/Arms, so each ampere from the drive produces a predictable increment of mechanical torque. Combined with the six-pole rotor, these characteristics provide high stiffness and fast response for closed-loop motion profiles.
The phase-to-phase DC resistance is 0.55 ohms, and the 30 mH inductance smooths current ripple so the amplifier can apply rapid vector control without excessive losses. A back electromotive force constant of 260 Vrms/kRPM relates shaft speed to generated voltage, requiring the drive to manage regenerated energy during deceleration. The integrated brake supplies 48 N-m of static holding torque at 24 VDC, securing vertical or suspended loads when power is removed. The rotor has an inertia of 0.0126 kg-m², which affects the acceleration available from a given torque command. A viscous damping factor of 0.36 N-m/kRPM characterizes speed-dependent mechanical resistance, while a 55-minute thermal time constant supports thermal model configuration and sustained-duty planning.
