Product Description:

The MHD115B-035-NP0-AA is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. In an automation cell, this unit converts drive commands from a digital controller into precise rotary motion for indexing tables, gantry axes, or packaging equipment across automated production lines. Integrated digital feedback lets the connected drive close the loop on position and velocity for high-repeatability moves during continuous operation.

At standstill, the motor can deliver a continuous torque of 50.0 Nm, allowing heavy loads to remain locked under closed-loop current without overheating. The aluminum frame has an IP65 rating, so dust and low-pressure water jets do not reach the internal windings. Position information is provided by a digital servo feedback (HSF) encoder with optical scanning, giving coarse and fine tracks to the drive. A 192 mm flange and a 180 mm centering diameter align the housing with standard machine plates, while natural convection through its ribbed surface removes waste heat without external blowers. Power is routed through a single output connector that exits on side A for compact wiring layouts.

The motor operates reliably between 0 to 40 °C, aided by F-class insulation that tolerates higher internal temperatures during cyclic duty. When inactive, it may be stored from -20 to +80 °C without performance drift, provided the installation remains below 1000 m above mean sea level. The internal mechanics reach a system accuracy of ± 0.5 angular minutes, supporting relative position detection routines that reference an external marker at power-up. A keyed shaft with an integral shaft seal keeps lubricant inside and contaminants outside, and the lack of a holding brake reduces mass for dynamic axes.
