Product Description:

The MHD112D-027-NP0-RN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as the rotary drive element in automated machine tools, gantry stages, and handling equipment, converting electrical control signals into controlled mechanical rotation. Within an automation loop, the motor supports rapid acceleration, precise positioning, and repeatable speed regulation for coordinated multi-axis motion. Its permanent-magnet design and closed-loop feedback arrangement help maintain high torque density while limiting thermal rise during continuous operation.

The winding code 027 corresponds to electrical characteristics suited to compatible servo drives, and the D-length housing increases the active iron stack within the 112-frame motor. At standstill, the motor can deliver a continuous 48.0 Nm without exceeding its thermal limits. Heat is removed through a jacket that supports liquid cooling, which helps the motor sustain output during prolonged low-speed operation. Rotor position is reported by digital servo feedback (HSF), and a centering shoulder of 130 mm helps align the flange with the machine interface. The motor is supplied without a holding brake, includes a shaft seal to restrict lubricant migration, and routes the power cable to the right side of the end bell.

The square mounting flange measures 192 mm across, allowing direct attachment to ISO mechanical adapters without extra shims. Torque is transferred through a keyed shaft, so couplings can be secured against slip under cyclic load. The internal counting electronics provide relative position detection, which allows the controller to establish a home reference before closed-loop moves begin. Electrical power enters through a sealed power connector, which simplifies connection and helps keep the liquid-cooling hoses clear of the motor face.
