Frequently Asked Questions

Why is an insulation grade F important for this servo motor?

The insulation grade F allows the MDD090C-N-020-N2L-110PA2 to withstand higher temperatures (up to 155 °C), increasing durability and reducing the risk of insulation failure under thermal stress.

How does the rated elevation of 1,000 m affect motor operation?

The operating up to 1,000 m altitude ensures the motor maintains cooling efficiency and electrical performance without derating, suitable for various factory floor elevations.

Why is the holding brake important in this servo motor?

The holding brake with 11.0 Nm torque in the MDD090C-N-020-N2L-110PA2 provides fail-safe stopping power, especially during power loss, preventing unintended movement and enhancing operational safety.

How does the thermal time constant of 60 minutes affect motor use?

The 60-minute thermal time constant allows the motor to manage heat dissipation efficiently, maintaining performance during extended cycles without overheating or thermal shutdown.

What is the significance of the IP65 protection rating?

The IP65 rating in the MDD090C-N-020-N2L-110PA2 guarantees protection against dust ingress and low-pressure water jets, making it suitable for harsh industrial settings where contamination could impair motor function.
