Why is a holding brake torque of 11 Nm important, and how should it be used?

The 11 Nm holding (blocking) brake allows the motor shaft to be locked when the motor is de-energized which prevents drift or movement of the load. It is not designed for braking a rotating load—using it to stop motion will cause premature wear or failure.

How does the centering diameter of 130 mm affect installation?

A larger centering diameter (130 mm) improves alignment accuracy when mounting onto flanges or housings that use that diameter for centering. It also means a larger physical envelope, so mechanical support, footprint, and alignment tolerances become more critical.

What impact does nominal speed 3000 min⁻¹ have on the achievable torque and power?

At 3000 rpm the motor is designed to deliver its rated torque at that speed. If you try to operate significantly above or below (especially above), mechanical stresses, bearing loads, and possibly cooling limits may be exceeded, reducing life or causing overheating.

In what applications would the model MDD093C-L-030-N2L-130GB1 motor be especially suitable, given its spec?

The MDD093C-L-030-N2L-130GB1 is well-suited for high precision motion control, such as press/punch machines, tool changers, pick-and-place, or automated assembly, where holding loads at standstill is needed, and precise digital feedback is required. Its sizeable diameter and surface cooling lend to heavier loads and moderate duty cycles.

How does having “plain shaft” rather than keyway affect its mounting and torque transmission?

A plain shaft (smooth) reduces vibration and mechanical stress at the shaft / coupling interface because there is no stress concentration from a keyway. However, coupling methods must ensure sufficient friction or clamp to avoid slippage, especially under high torque.
