Product Description:

Bosch Rexroth Indramat manufactures the MHD112D-024-NP0-BN in the MHD Synchronous Motors series. This servo motor converts electrical energy into controlled rotary motion for positioning axes, conveying stages, and similar automation tasks where closed-loop velocity and torque control are required. It is suited to machines that need repeatable motion, stable speed regulation, and accurate response to changing loads during normal operation. Because the motor is intended for servo applications, it supports responsive acceleration and deceleration when used with a compatible controller.

The motor can deliver a standstill torque of 48.0 Nm, allowing it to hold or start heavy loads without additional gearing. Heat generated during operation is removed through liquid cooling, which supports continuous output even inside sealed machine housings. Mechanical attachment uses a 192 mm square flange with a 130 mm centering diameter to keep the motor aligned with the driven assembly. Motion feedback is supplied by a digital servo feedback (HSF) encoder that sends high-resolution incremental data to the drive for relative position tracking. This feedback arrangement lets the control system monitor rotor movement continuously and supports precise homing at startup. The size 112 stator cross-section provides a larger active iron volume, and the D frame length increases stack depth to support higher torque capacity.

Electrical power reaches the stator windings through a connector on side B of the housing, which can simplify cable routing when the driven load is positioned opposite the bearing end. The winding code 024 matches the electrical values expected by the paired drive. A keyed shaft transfers torque securely, and a shaft seal helps keep coolant or lubricant from migrating along the journal into the motor interior. The unit is supplied without a holding brake, so load holding at rest must be provided by the machine or drive system when power is removed.
