Product Description:
The BH-226-C-63-B3E106 is a servo motor manufactured by Kollmorgen and offered in the Kollmorgen Goldline B and BH Motors series. It is intended for closed-loop industrial automation where precise velocity and position control are required, such as indexing tables and coordinated multi-axis assemblies. The motor converts current from a matched drive into rotational torque that can be coupled directly to the machine load. This makes it suitable for applications that need repeatable motion and steady control during changing operating conditions.
Under continuous stall conditions, it delivers 5.6 N-m while drawing 4.46 Arms. This operating point represents the continuous load the motor can hold without overheating. The peak stall capability is 19.5 N-m at up to 16.5 Arms, giving additional torque for acceleration and short-duration demand. The phase inductance is 44 mH, which helps moderate current rise for smoother drive response, while the dc resistance of 4.12 Ω limits steady-state losses. Its outside diameter is 92 mm, giving the unit a compact mechanical envelope, and the four-pole rotor supports synchronous operation with standard digital drives. A torque constant of 1.25 N-m/Arms links commanded current to output torque, which supports predictable current-based control.
The motor includes an electromagnetic brake with 6 N-m of holding torque when powered by 24 VDC, allowing vertical axes to remain fixed when input power is removed. Its back-emf constant is 75.4 Vrms/kRPM, which indicates the generated voltage in relation to speed and helps match the motor to an appropriate bus voltage. The rotor inertia of 0.000251 kg-m² supports rapid speed changes, and the shaft dimensions of 14 mm diameter and 30 mm extension fit common coupling arrangements. Thermal response is relatively gradual, with a thermal time constant of 21 min, so winding temperature changes occur progressively during cyclical duty.
