The R911282008 (MHD090B-035-PP0-UN) is a synchronous servo motor designed for industrial automation applications. This motor utilizes electronic commutation for high peak torque across a wide speed range and employs liquid cooling for heat dissipation, ensuring consistent performance and high overload capacity. It features a keyed shaft with a shaft seal, a 140 mm flange, a centering diameter of 110 mm, and motor length B. The unit offers a continuous standstill torque of 12.0 Nm, does not include a holding brake, and supports digital servo feedback with absolute position detection exceeding 4096 revolutions. Power and feedback connections are provided via turnable connectors adjustable within 270 degrees. Winding code is 035.

Can the MHD090B-035-PP0-UN be installed in compact enclosures with limited airflow?

Yes, because it uses liquid cooling, it doesn’t rely on ambient airflow for thermal management. This makes it suitable for sealed or densely packed control cabinets.

What type of application benefits from absolute position detection over 4096 revolutions?

Multi-turn absolute encoders are ideal for motion systems requiring power loss recovery without rehoming. This is crucial in robotics, gantry systems, and vertical axes.

Does the lack of a holding brake limit vertical axis applications?

Yes, without a holding brake, external mechanical braking or power-on torque must secure the load when powered off. It's not ideal for vertical axes unless additional measures are taken.

What role does the 12.0 Nm continuous torque play in motion system design?

It defines the sustained load capacity without overheating under rated conditions. This helps size the motor accurately for duty cycles in automation or machining tasks.

What considerations are needed when using liquid-cooled motors like this one?

A reliable coolant circuit with proper flow and temperature control is mandatory. System design must include leak detection and regular maintenance planning.
