Frequently Asked Questions

How does the centering diameter (130 mm) impact installation and torque transmission?

The centering diameter defines how the motor is mounted to mating parts (e.g. flange, coupling) and how loads are aligned. A correctly matched centering diameter in MDD093C-L-030-N2L-130GL motor ensures minimal misalignment, reducing vibration, bearing loads, and mechanical wear.

Why is “connector” type connection chosen over terminal box or direct wiring?

Connector‐type allows quicker, more reliable connections/disconnections, often with sealed plugs to aid in environmental protection. In the case of MDD093C-L-030-N2L-130GL motor connectors can simplify maintenance and reduce wiring errors, but require matching connector hardware and ensuring good sealing.

Why is digital servo feedback (DSF) used, and what difference does it make in control accuracy?

The DSF provides high-resolution information on rotor position and speed, allowing tight control loops with reduced error and quicker response. For MDD093C-L-030-N2L-130GL, it means better repeatability and smoother motion in precision tasks.

How does the “shaft seal” in this motor affect its lifespan and performance?

The shaft seal prevents dust, moisture, or contaminants from entering via the shaft, protecting internal bearings and rotor components. This reduces maintenance frequency and helps maintain efficiency over time, especially in harsher environments.

What benefit does the 11 Nm holding (blocking) brake provide in the MDD093C-L-030-N2L-130GL motor?

The holding brake ensures the shaft stays locked when power is removed, preventing drift or motion under load. It is especially useful for applications with vertical loads or where precise stoppage is required without continuous torque from the motor.
