Product Description:
The MHD041A-144 is a small-frame servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a permanent-magnet synchronous unit, it converts commanded stator currents into precise rotary motion, making it suitable for axes that demand tight velocity and position control in packaging lines, compact pick-and-place heads, or light gantry stages. The motor integrates with Rexroth digital drives, where its built-in feedback supports closed-loop control of torque and speed.
The mechanical interface follows industry envelope codes. A centering recess with a diameter of 50 mm aligns the flange to gearboxes or machine plates, minimizing radial runout. Mounting holes share an 82 mm square flange, so the motor can replace earlier IEC-compliant frames without adapter rings. The rotor has size 041, which corresponds to the active iron length and magnet set used in this frame. Length code A marks the shortest stator stack offered in this family, which lowers mass and helps achieve rapid acceleration on light loads. During static holding, the electromagnetic system supplies 1.3 Nm of continuous torque, allowing the axis to resist external disturbances without overheating when stopped under rated current.
Electrical behavior is set by winding code 144, which sets the phase resistance and inductance that the matching drive uses for stable current loops. The unit is a compact Servo Motor, and its integrated sensors report absolute rotor position for closed-loop speed and position control during operation. The motor belongs to the MHD Synchronous Motors series, where shaft dimensions, cooling surfaces, and feedback pinouts stay consistent across frame sizes. This common layout helps keep motor connections straightforward in compact machine spaces.
