The R911290643 (MHD131D-024-PP2-AN) is a Bosch Rexroth MHD-series synchronous servo motor engineered for compatibility with Rexroth Indramat digital drive converters. It accepts an AC input voltage of 117-279 V (±15%) and can be configured with natural or surface (blower-assisted) cooling. At 1000-1500 rpm, it supplies continuous power from 7 to 26.5 kW, with a nominal current of 23.2 A (natural cooling) or 57.8 A (surface cooling). Key features include an IP65-rated black coated housing, 148 Nm continuous torque, 240 Nm electrically-released holding brake, and a digitally integrated multiturn absolute encoder (>4096 revolutions) for position detection. The motor features a keyed shaft, centering diameter of 250 mm, 260 mm flange, and weighs 113 kg excluding the brake. The design supports a 0-40°C ambient temperature range and employs an A-side output connector for power.

Frequently Asked Questions

Why is side-A power connection used in MHD131D-024-PP2-AN?

It positions cabling toward the operator side for access. This placement simplifies maintenance in panel-mounted assemblies.

How does MHD131D-024-PP2-AN maintain alignment during installation?

It uses a 250 mm centering diameter for accurate fit. This alignment minimizes imbalance and vibration.

Why is the D-length configuration valuable in MHD131D-024-PP2-AN?

It achieves compact geometry while preserving torque density. This combination supports smooth acceleration response.

How does MHD131D-024-PP2-AN support load retention after power loss?

It engages the holding brake immediately when voltage drops. This feature prevents unplanned motion or slipping.

Why does MHD131D-024-PP2-AN suit automated production lines?

It runs continuously with controlled temperature and high precision. This makes it reliable for multi-shift manufacturing.
