Product Description:

The MHD131D-024-PP0-AN is a servo motor manufactured by Bosch Rexroth Indramat and belongs to the MHD Synchronous Motors series. It is intended for closed-loop industrial axes, where it converts electrical energy into controlled rotary motion for packaging lines, machining centers, and material-handling equipment. The motor has a keyed shaft for direct coupling and comes without a holding brake, so the load must be secured by the machine when power is removed. Its synchronous design allows the drive controller to regulate torque and speed with high responsiveness during positioning and interpolation tasks.

It provides a continuous standstill torque of 160 Nm, which supports static load holding without overheating during rated operation. The mounting interface uses a 260 mm square flange, and the housing is sealed to IP65 to keep out dust and water jets. Heat is removed by liquid cooling, and the windings use Class F insulation for elevated thermal endurance. The motor has size 131 with length code D and winding code 024, while the keyed shaft includes a seal and power is connected on side A. Operation is permitted up to 1000 m above sea level, and the cooling arrangement supports stable temperature control in continuous-duty service.

Position feedback is handled by digital servo electronics that use an optical measurement method to maintain a system accuracy of ± 0.5 angular minutes. Absolute feedback over more than 4096 revolutions allows the axis to retain position information after power loss, which reduces the need for a homing cycle at startup. The encoder circuitry operates within a normal ambient range of 0 to 40 °C, and the motor can be stored at –20 to +80 °C without damage. This operating range supports repeatable motion on equipment that runs frequent start-stop cycles and must return to service with consistent feedback behavior.
