The R911278440 (MHD090B-035-NG1-UN) is a permanent magnet servo motor engineered with low inertial mass, utilizing specialized magnet materials. This model employs a brushless design with grease-lubricated bearings and features a closed, IP65-protected housing for operation in demanding environments. The motor supports liquid cooling and includes a holding brake with an 11.0 Nm torque rating. Key specifications include a 12.0 Nm continuous standstill torque, digital servo feedback (HSF) encoder for relative position detection, and a plain shaft with a shaft seal. The device has a centering diameter of 110 mm, a flange size of 140 mm compliant with DIN 42948, and a motor length designated as B. Its power connection is turnable within a 270° range and incorporates both power and feedback connectors. The winding code is 035.

Frequently Asked Questions

Does the holding brake on the MHD090B-035-NG1-UN provide dynamic braking?

No, the holding brake is designed only for static holding when power is removed. It is not rated for motion braking or emergency stop functionality.

Why is a high-resolution digital feedback encoder useful in precision applications?

It enables fine position control down to arc-second resolution, minimizing error during motion. This is critical for synchronized multi-axis operations or micro-positioning.

What’s the practical effect of the 12.0 Nm continuous torque at standstill?

It ensures stable load holding during dwell periods without the need for additional external braking. This is especially valuable in vertical axis or clamping applications.

Can the MHD090B-035-NG1-UN be used in multi-axis automation systems?

Yes, its integration-ready encoder and standard flange dimensions support tight coupling with modular drive systems. That makes it suitable for gantries, pick-and-place arms, and robotic platforms.

Is the shaft seal sufficient for dusty or oily environments?

The integrated shaft seal helps protect the internal bearings and encoder from contaminant ingress. It increases reliability in machining, food packaging, or press automation setups.
