Product Description:

The MHD115C-059-NG0-BN is a servo motor built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for closed-loop industrial axes where continuous torque, fast feedback response, and compact mounting are required. Within an automation cell, this motor converts drive current into rotational motion that the controller can regulate precisely through the integrated feedback circuit. This operating principle suits positioning, speed control, and synchronized motion in machinery that depends on accurate axis response during repeated cycles.

The motor has a centering diameter of 180 mm, which aligns the frame accurately to the host machine, and a flange size of 192 mm, which fits standard bolt patterns. Winding code 059 supports a continuous standstill torque of 70.0 Nm, and liquid cooling passages remove heat so the motor can maintain rated output during continuous operation. Because heat is carried away through internal cooling passages, the motor can be used in demanding duty cycles without relying on external airflow around the housing. A plain shaft transfers torque to the load, and the motor is supplied without a holding brake for applications that use external locking. Motor size 115 with length code C gives the unit a longer active section, and the power conductors exit through an output connector for straightforward cable routing.

Position information is provided through relative position detection from a digital servo feedback (HSF) encoder, allowing the drive to track incremental movement with high resolution. This feedback arrangement supports stable commutation and accurate motion control during acceleration, deceleration, and steady-state operation. The three-phase connections are arranged on side B, which helps keep cables clear of nearby machine components, and a shaft seal protects the bearing area against coolant or oil. The cable orientation and sealed shaft area help maintain orderly installation and reduce the chance of contamination reaching internal mechanical parts during continuous-duty use.
