Product Description:
The MHD112A-035-NG0-AP is a three-phase servo motor built by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. It combines a size 112 stator with an A-length housing to supply precise rotary motion for automated machine axes in positioning and speed-controlled applications. Its compact housing format helps the motor fit machine layouts where servo performance is required without excessive installation length. A plain shaft transmits torque directly to couplings, and the unit is supplied without a holding brake, suiting systems that rely on drive torque or external clamps when power is removed. Power cabling enters on side A through an output connector that supports straightforward wiring and consistent cable routing.
The motor can maintain a continuous standstill torque of 15.0 Nm, allowing stable force output during positioning or dwell phases. Position feedback is generated by a digital servo feedback (HSF) encoder that is scanned optically, so the control loop receives high-resolution data without mechanical wear. This feedback device supports accurate commutation and closed-loop speed regulation during operation. A centering shoulder of 130 mm helps align the motor on the machine frame, while the housing has an IP65 rating to block dust and low-pressure water. Thermal exchange occurs by natural convection, and the stator assembly is built with IP68 protection against moisture ingress, eliminating the need for forced-air or liquid cooling.
The square flange spans 192 mm, giving the mounting face a broad footprint for heavy loads, and the insulation system is classified as F, permitting winding temperatures up to 155 °C under cyclic duty. During operation, the motor may run in ambient ranges of 0 to 40 °C, and it can be stored from −20 to +80 °C without degradation while unpowered. Angular repeatability stays within ± 0.5 angular minutes, and a shaft seal helps keep lubrication free of contaminants. The flange size and repeatability help maintain alignment accuracy at the load connection during repeated motion cycles. Installation is approved up to 1000 m above mean sea level, and the stated winding code remains compatible with the drive's offset data.
