Product Description:

The BH-124-B-63 is a brushless AC servo motor manufactured by Kollmorgen as part of the Kollmorgen Goldline B and BH Motors series. It is intended for industrial automation axes where a compact motor must deliver repeatable torque under digital drive control. This allows machinery to follow precise speed or position commands during coordinated motion. Its compact format suits installations where servo performance is needed without using a larger motor frame.

This model draws a continuous current of 1.8 ARMS, and that current produces a continuous rated torque of 1.06 N-m at the shaft. A rated speed of 7500 rpm is the maximum sustained speed under nominal load, while a supply of 480 VAC matches the winding design to common three-phase drive buses. The line-to-line inductance is 58 mH, which influences current ripple and the attainable current loop bandwidth in the connected drive. Rotor inertia is only 0.0000461 kg-m², and that low moment of inertia supports fast acceleration without excessive drive effort. During continuous operation, the motor can resist stall at 1.3 N-m. Its frameless resolver provides analog sine-cosine feedback for the drive controller, allowing the control loop to monitor rotor position continuously. A standard metric flange simplifies attachment, and the Interconnectron power and feedback connector groups conductors into a single plug.

Transient demands are handled by a peak rated torque of 3.78 N-m and a peak stall torque of 4.2 N-m, both available when the drive supplies up to 6 ARMS for short durations. These overload margins let the axis overcome friction or rapid load changes without oversizing the motor for continuous duty. The housing length is 234.5 mm without a brake, so an external holding mechanism is required if static locking is needed. The motor has no shaft seal, so it is suitable for clean, dry enclosures. No mating plugs are included with the unit.
