Product Description:
The MHD041B-144-NG0-UN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. In an automation cell, the unit couples with a matching drive controller to deliver regulated torque and velocity for tasks such as pick-and-place heads, indexing tables, or compact conveyors. By providing closed-loop electromechanical power in the 041 frame size, it allows precise load positioning while keeping the installation footprint small. The motor is intended for axes that need repeatable motion under varying loads, because the drive can continually correct current and speed during operation.
Mechanical interface dimensions show how the motor mounts to a machine frame. A flange diameter of 82 mm aligns with standard gearbox patterns, while the centering register measures 50 mm to locate the housing concentrically in the mounting bore. Under continuous duty at standstill, the rotor supplies 2.7 Nm of torque, enabling static holding or slow-speed feed without overheating. Thermal energy is extracted through liquid cooling, so output remains stable even when the ambient enclosure retains heat. Electrical behavior is set by winding code 144, which fixes resistance and inductance values expected by Indramat drives and determines the nominal current required for rated torque. The B length variant adds stack height to accommodate this winding without increasing the overall diameter.
Connection features support flexible cabinet layouts and axis integration. The power connector can be rotated through 270°, letting harnesses exit in the optimal direction for tight spaces. A plain shaft simplifies coupling to clamps or friction wheels, and a shaft seal is fitted to guard the interior bearings against coolant or oil ingress. Feedback is provided by a digital servo feedback (HSF) encoder, giving the drive high-resolution relative position data for speed and commutation loops. This feedback arrangement also supports smooth startup and stable control across low-speed and reversing moves. Because the motor is supplied without a holding brake, the machine must rely on external locking devices when power-off torque retention is required.
