Frequently Asked Questions

What is the nominal speed of MDD093C-F-030-N2L-110GB1 motor?

The MDD093C-F-030-N2L-110GB1 motor operates at a nominal speed of 3000 rpm for balanced torque and efficiency. This rating supports dynamic automation where precise speed regulation is critical for synchronized motion.

How does the cooling system function in this motor?

It uses surface cooling through natural convection to dissipate heat across the housing. This passive cooling minimizes noise, reduces moving parts, and ensures thermal stability during continuous operation.

What is the role of the integrated holding brake?

An 11 Nm electromagnetic holding brake secures the motor shaft during power-off conditions. This prevents unintentional movement on vertical or suspended loads, improving safety and system reliability.

How does the feedback system enhance operation of MDD093C-F-030-N2L-110GB1?

The MDD093C-F-030-N2L-110GB1 motor includes a digital servo feedback encoder for accurate position sensing. This ensures consistent torque delivery, smooth motion control, and dependable communication with compatible servo drives.

What thermal management practices improve durability in this motor?

Adequate airflow and proper mounting clearances optimize natural convection efficiency. Connecting the integrated PTC sensor to the drive helps prevent overheating and extends winding insulation life in demanding cycles.
