Why is brake torque essential in MKD112B-048-GG1-AN?

It applies 22 Nm holding torque. This locks axes safely during power-off, particularly in vertical loads.

Why does cooling method matter in MKD112B-048-GG1-AN?

It employs a radial fan system. Forced air circulation enhances thermal dissipation during high-output duty.

Why is maximum speed important for MKD112B-048-GG1-AN?

The motor achieves up to 6000 RPM, enabling high-speed motion for rapid traverses in automated systems, reducing cycle times while maintaining positional accuracy and controlled dynamics.

How does flange geometry strengthen MKD112B-048-GG1-AN?

Featuring a 192 mm flange, the motor distributes mounting and coupling forces evenly, enhancing mechanical rigidity, minimizing vibration, and ensuring stable operation during high-torque or high-speed cycles.

What benefits arise from feedback design in MKD112B-048-GG1-AN?

It employs resolver feedback. Noise immunity ensures reliable performance in electrically intense factories.
