Frequently Asked Questions

Why is digital servo feedback used in the model MDD090C-N-020-N5L-130GA1 motor?

The Digital servo feedback provides high resolution rotor position and speed information, enabling precise motion control and contouring. In the MDD090C-N-020-N5L-130GA1, this feedback supports smooth start-stop and dynamic acceleration profiles required in CNC and packaging machinery.

How does the winding inductance value of 7.6 mH affect motor performance?

The windings’ inductance of 7.6 mH limits the rate of current change, reducing electrical noise and improving stability during high-speed switching. This leads to smoother torque delivery and reduced electromagnetic interference in drive systems.

In what types of applications is the MDD090C-N-020-N5L-130GA1 typically used?

The MDD090C-N-020-N5L-130GA1 motor is commonly used in CNC tools, packaging lines, and printing machinery where precise servo control and holding capability are needed. Its continuous torque and brake feature make it ideal for indexing, positioning and high-cycle automation tasks.

How does the nominal speed of 2 000 min⁻¹ benefit integration in automation setups?

A nominal speed of 2 000 min⁻¹ aligns with many standard servo drive systems and gearboxes, offering a good compromise between torque and speed. It allows direct coupling or simple gearing without major modification in many machine designs.

How does the shaft seal contribute to the suitability of the MDD090C-N-020-N5L-130GA1 motor for industrial use?

The motor’s shaft seal helps prevent ingress of dust, coolant or other contaminants, preserving bearings and rotor integrity. This prolongs service life and allows the motor to be used in harsher environments typical of manufacturing plants.
