The R911296635 (MHD112B-024-NG0-LN) is a synchronous servo motor in the MHD series by Bosch Rexroth. It features a flange size of 192 mm, centering diameter of 130 mm, and a B-length frame design. This model is equipped with electronic commutation and is designed for high-frequency start-stop operations. The stator windings transfer heat to the outer housing, aided by liquid cooling, and integrated temperature monitoring is provided. The housing is sealed to IP65, and the shaft is designed for a friction-locked shaft-hub connection with a plain shaft and shaft seal. The motor operates at a nominal speed of 2,500 rpm and a maximum speed of 4,000 rpm, with a continuous standstill torque of 28.0 Nm. Digital servo feedback (HSF) is used for relative position detection, and the power connector is oriented to the left. No holding brake is included.

Frequently Asked Questions

What are the installation considerations for the power connector positioned to the left?

Cabling must be routed to avoid strain or interference with moving machine parts. Proper clearance ensures easier maintenance and reliable electrical connections.

What is the role of relative position detection in control accuracy?

Relative encoders require homing at startup to establish reference position. Once initialized, they deliver precise incremental tracking for closed-loop control.

Can the MHD112B-024-NG0-LN operate in dusty or humid environments?

Yes, if properly sealed and integrated with its shaft seal and housing protection. Adequate enclosure and coolant system integrity are key to reliable operation.

What benefits does a continuous torque of 28 Nm provide in servo applications?

It supports high-load processes like pressing or rotary indexing without torque drop. This ensures consistent performance during long duty cycles.

Why is a plain shaft design preferred in some automation setups?

Plain shafts simplify coupling with gearboxes or pulleys and reduce alignment complexity. However, they rely on external retention systems for axial load handling.
