The R911279633 (MHD112D-024-PP3-BN) is a servo motor equipped with an integrated digital encoder for absolute position detection exceeding 4096 revolutions and features a keyed shaft with shaft seal. The motor provides a holding brake with 70 Nm torque, activated with a 24 V DC signal, and optional lower torque variants are available. With a flange size of 192 mm, centering diameter of 130 mm, and motor length D, it is designed for mounting using four flange holes. The housing is rated IP65 for dust and moisture protection and supports liquid or surface cooling. Continuous torque at standstill is 48 Nm. Operational parameters are 0–40°C ambient temperature and up to 1000 m altitude. Power is connected on side B using an output connector. Installation is to be performed by trained personnel only.

Frequently Asked Questions

What is the centering diameter specification?

The centering diameter is 130 mm, matching the standardized series housing interface. The dimension ensures precise radial alignment with machine flanges and avoids misalignment in multi-axis assemblies.

How long is the motor housing overall?

The motor housing length is 526 mm for the PP3 version. The extended length accommodates internal windings, torque output, and mounting of auxiliary components such as brakes or encoders.

What is the shaft diameter and accessible length?

The shaft diameter is 32 mm, with about 60 mm accessible outside the housing. The specification provides sufficient coupling area for keys or hubs and ensures secure torque transmission.

How are the mounting flange dimensions specified?

The flange size is 192 mm for the MHD112 series motors. The flange matches standard mounting patterns and ensures bolt compatibility with industrial frames and adapters.

What shape does the housing adopt for cooling purposes?

The housing is cylindrical with fins allowing natural convection or surface cooling. The external geometry increases surface area, aiding thermal dissipation and maintaining consistent operating temperature.
