Why is brake torque significant in MKD112B-048-GG1-BN?

The motor includes a 22 Nm holding brake, which secures stationary loads under gravity or external force. This prevents slippage in vertical axes, enhancing safety and reducing external clamping needs in multi-axis machines.

How does radial cooling benefit MKD112B-048-GG1-BN?

It employs radial cooling, where forced airflow dissipates excess heat. This improves winding insulation longevity and enables stable torque output, particularly in continuous production processes with high duty cycles and thermal demands.

Why does bearing lubrication matter in MKD112B-048-GG1-BN?

Its bearings are lifetime lubricated, removing the need for scheduled lubrication. This minimizes maintenance intervals, reduces downtime costs, and ensures reliable support of shaft loads through long-term continuous duty.

How does the flange design help MKD112B-048-GG1-BN?

The 192 mm flange provides a wide, stable mounting surface. This increases structural rigidity and maintains alignment during torque transmission, which is crucial for reducing vibration in machine tool applications.

What role does shaft configuration play in MKD112B-048-GG1-BN?

It features a plain shaft, simplifying coupling to gearboxes. This design reduces backlash, increases stiffness, and enables smoother torque transfer, supporting precision in applications requiring repetitive positioning.
