Product Description:

The MHD115C-058-NG1-BN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. This unit integrates digital servo feedback and an internal holding brake to provide controlled torque and position data for industrial automation axes. By converting electrical energy into regulated mechanical rotation, it supports machine tools, packaging stations, and handling modules that demand coordinated motion profiles with repeatable precision. Its synchronous operation allows the connected drive to regulate speed and position continuously, which is useful on feed axes, indexing tables, and transfer systems.

The motor has a 180 mm centering diameter and a 192 mm square flange, while motor size 115 and length code C establish the housing envelope. Its plain shaft provides 70.0 Nm of continuous standstill torque, and the holding brake supplies the same torque for power-off retention. Heat is removed by liquid cooling, and the enclosure is sealed to IP65 to resist dust and low-pressure water jets. Power is routed through a connector on side B, and the optical measuring system works with digital servo feedback for relative position detection. Installation is permitted up to 1000 m above mean sea level, and storage is allowed from -20 °C to +80 °C.

The motor uses F-class insulation and can operate in ambient temperatures from 0 to 40 °C without derating. That insulation class supports the winding during repeated acceleration and deceleration cycles. A shaft seal helps keep dust and coolant away from the bearing chamber, which supports reliable bearing protection in washdown-prone or dirty machine areas. The optical feedback system provides ±0.5 angular-minute system accuracy, helping the drive correct small position deviations during indexing, contouring, and other precise motion tasks.
