The Indramat MPN R911277130 (MHD090B-035-NP0-UN) is a low-inertia, permanent magnet servo motor designed for use in automation and motion control applications. It features electronic commutation, a brushless design, and pre-greased bearings for reduced maintenance. The motor has a liquid-cooled housing, a keyed shaft with shaft seal, and supports a maximum speed of 5000 RPM with a rated continuous torque of 12.0 Nm. It utilizes digital servo feedback (HSF) for relative position detection, includes a temperature monitoring system, and incorporates a DIN 42948 flange for flexible mounting. The power connection is turnable within 270°, mass is 14 kg, centering diameter is 110 mm, motor size is 090, motor length is B, peak current is 49.5 A, and it is rated for installation up to 1000 m above mean sea level. The motor is supplied without a holding brake.

Frequently Asked Questions

What are the advantages of using liquid cooling in servo motors like the MHD090B‑035‑NP0‑UN?

Liquid cooling enables higher thermal dissipation, allowing the motor to sustain higher torque without overheating. It also permits compact motor designs in thermally constrained environments.

Can the MHD090B‑035‑NP0‑UN be installed above 1000 meters elevation?

It is optimized for use up to 1000 m; above this, air pressure and cooling efficiency drop, potentially requiring derating. Custom installation adjustments or additional cooling may be needed for higher elevations.

Why is a digital servo feedback (HSF) encoder important in automation?

HSF encoders offer precise, high-resolution relative positioning, essential for closed-loop control in fast, dynamic systems. They support accurate velocity and torque regulation in real-time.

What implications does the 4-pole pair design have on motor performance?

How should wiring be handled for motors with separate power and feedback connectors?
