Product Description:

The MHD112C-058-NP3-AN servo motor is built by Bosch Rexroth Indramat for the MHD Synchronous Motors series. As a brushless permanent-magnet motor, it provides closed-loop rotary motion for CNC axes, material-handling stations, and other automation tasks that require accurate speed and position control. The motor uses frame size 112 with length code C, giving it a midsized format that balances torque output with available installation space. In typical systems, it operates with an intelligent drive controller, and its feedback channel supports stable positioning during changing load conditions.

At standstill, the motor delivers a continuous torque of 38.0 Nm, and heat is removed by liquid cooling, which helps keep copper temperatures within Class F limits. A 192 mm mounting flange and a centering diameter of 130 mm establish the mechanical interface for accurate alignment on the machine. The motor uses a keyed shaft with an integral shaft seal, which supports reliable torque transmission and helps keep contaminants away from the shaft opening. System feedback is supplied by Digital servo feedback (HSF), which uses an optical measurement method to provide precise rotor position data to the drive. Electrical power reaches the stator through a connector on side A, and the housing is rated IP65, which helps protect internal components from dust and low-pressure water exposure.

The integrated brake provides 70.0 Nm of holding torque when power is removed, helping the axis remain in position at a stop. Motion changes can be resolved within ±0.5 angular minutes, which supports accurate correction of small command deviations during closed-loop operation. Safe operation is permitted at ambient temperatures from 0 to 40 °C, and storage is permitted from –20 to +80 °C. Installation is allowed up to 1000 m above sea level without derating. The relative position detection arrangement helps the control system maintain repeatable movement after stopping, restarting, or completing homing sequences.
