The R911319931 (MHD131D-024-NP2-BN) is a synchronous servo motor engineered by Bosch Rexroth Indramat, featuring a keyed shaft, shaft seal, and digital servo feedback (HSF) for relative position detection. This motor operates on a 3-phase AC supply with a nominal voltage range of 400V to 480V and provides a continuous standstill torque of 160 Nm. Its holding brake delivers 240 Nm torque. The unit is equipped with four pole pairs and a winding code of 024, with winding resistance at 0.08 Ω and inductance at 2.5 mH. The motor achieves a characteristic speed of 2000 rpm and weighs 113 kg. The housing has IP65 protection, suitable for environments from 0°C to +40°C, and includes liquid cooling. It incorporates a thermal time constant of 140 minutes for natural cooling and 60 minutes for surface cooling, and is classified with insulation class F according to DIN VDE 0530 Part 1.

Frequently Asked Questions

How does the side B power connection aid installation efficiency?

Side B placement helps organize cabling in space-restricted control setups. It supports neater wiring paths and reduces connector interference near adjoining machinery.

Why is the MHD131D-024-NP2-BN motor ideal for repetitive motion cycles?

Its liquid-cooled housing keeps internal components within steady thermal limits. Continuous cooling enables dependable torque delivery through long operational sequences.

What benefit does the keyed shaft with seal provide in MHD131D-024-NP2-BN?

The key prevents rotational slip while the seal protects bearings from contaminants. Combined design enhances torque reliability and safeguards internal parts from wear.

How does relative position detection support quick motion restarts?

Relative sensing allows the controller to resume operations without lengthy calibration. It maintains process flow after brief shutdowns or system resets.

Why is motor length D beneficial for torque and balance control?

Length D construction offers balanced rotor inertia across torque ranges. The proportioned length promotes vibration reduction during acceleration and deceleration phases.
