Product Description:

The MHD131D-024-NG2-BN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It drives large loads with precise velocity and position control in automated production equipment, supporting synchronized multi-axis motion in gantry systems, presses, and high-torque spindle applications. The motor operates with a digital drive controller that modulates its windings, while an integrated optical encoder supplies real-time rotor data to the control loop.

At the stator, this model delivers a continuous standstill torque of 160 Nm, allowing stable holding or low-speed machining without overheating. Heat is removed through liquid cooling, which helps keep the windings within the insulation limit during sustained demand. The housing carries an IP65 protection rating, providing complete dust protection and resistance to directed water jets. Mounting interfaces use a 260 mm square flange, and concentric alignment is secured by a 250 mm centering diameter. Position feedback is provided by optical digital servo feedback with a relative measuring system, so the control system performs absolute referencing after power-up.

An integrated holding brake provides 240 Nm of torque and engages automatically when power is removed. During motion, the encoder maintains a system accuracy of ± 0.5 angular minutes, supporting fine contouring and coordinated axis interpolation. The motor is rated for continuous operation within an ambient range of 0 to 40 °C, and installation is permitted up to 1000 m above mean sea level without derating. Winding code 024 identifies the electrical characteristics used for drive matching. Additional features include a plain shaft with a factory-installed shaft seal and a power connector oriented on side B for straightforward cable routing.
