Product Description:

The MHD112D-027-PG3-BN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It works with a drive controller to convert commanded current into controlled mechanical rotation for indexing tables, gantry axes, and other automated motion tasks. Its permanent-magnet rotor, integrated feedback system, and internal cooling circuit support repeatable positioning during demanding duty cycles. This helps the motor maintain stable operation in applications that require accurate motion over long production runs.

A centering diameter of 130 mm aligns the housing concentrically with the machine plate and helps maintain accurate shaft positioning after installation. At standstill, the motor can deliver 48.0 Nm of continuous torque for low-speed process control and controlled holding under load. Position and speed are reported through Digital servo feedback with an integrated multi-turn encoder, so the drive can monitor motion continuously during closed-loop operation. The square flange measures 192 mm, providing a rigid mounting face, and internal coolant passages support Liquid cooling for applications that run in enclosed spaces or under heavy thermal demand.

The holding brake is rated at 70.0 Nm and secures the shaft when control power is removed, which is useful on vertical or suspended axes. Mechanical output is carried through a plain shaft, making the motor suitable for clamp-style couplings and shrink-disk connections. The feedback system stores absolute position across over 4096 revolutions, so the axis can retain position information through power cycles without a homing move at startup. Winding code 027 matches the electrical characteristics expected by compatible Rexroth drives, while a shaft seal and the B-side connector arrangement help protect the assembly and keep cable routing orderly.
