Frequently Asked Questions

What is the significance of the IP65 protection rating for this servomotor?

The IP65 rating seals the motor against dust and protects it from low-pressure water jets. It allows reliable use in dusty or washdown industrial environments.

How does insulation class F benefit long-term performance?

Class F insulation withstands 155°C winding temperatures. It protects against thermal stress and extends motor life.

What does a sound pressure level below 75 dB[A] imply in practice?

The motor runs with low noise output. It suits applications where quiet operation is important.

Why is the ambient operating range limited to 0–40°C?

The design cools the motor effectively in moderate climates. Running it outside this range requires derating or extra cooling.

How does natural convection cooling affect the motor’s reliability?

Natural convection cools the motor without fans. It reduces mechanical wear and lowers maintenance needs.
