Product Description:
The MHD112C-058-PG3-RN is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It executes closed-loop industrial automation tasks by translating drive commands into regulated rotation for common machine axes such as feed drives, transfer units, and positioning systems. The unit uses motor size 112 and length code C, while winding code 058 identifies the stator configuration for this frame. Its digital servo feedback system uses an integrated optical encoder to return multi-turn absolute rotor position to the controller. This arrangement allows the connected drive to monitor rotor angle continuously for commutation, speed control, and precise position correction during repeated cycles.
Thermal and mechanical performance are supported by liquid cooling, which transfers loss heat to an external circuit and allows the motor to deliver a continuous shaft torque of 38.0 Nm without derating. The housing is sealed to IP65, helping protect internal components from dust and low-pressure water jets in demanding machine environments. Mounting is handled through a 192 mm square flange that aligns on a 130 mm centering boss for coaxial seating and secure machine attachment. Position feedback accuracy at the shaft remains within ±0.5 angular minutes, giving the drive fine interpolation capability for contouring tasks. The face-mounted arrangement helps preserve alignment between the motor shaft and the driven mechanism, while power enters through a right-facing connector and the plain shaft includes a shaft seal.
An integral holding brake supplies 70.0 Nm of static torque to secure the axis when power is removed. Class F insulation supports elevated winding temperatures, and the motor maintains rated output in ambient conditions from 0 to 40 °C. The brake is intended to hold the load at standstill, while storage is permitted between -20 and +80 °C and installation is allowed up to 1000 m above mean sea level without derating. These limits support indoor industrial use where stable thermal performance and secure axis holding are required.
