Product Description:

The MHD112C-058-NG3-BN is a servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It is intended for closed-loop industrial axes that require precise, continuous rotary motion and direct feedback to the drive controller. When used with digital amplifiers, the motor converts electrical power into mechanical torque for positioning tables, pick-and-place heads, and converting equipment in automated machinery.

It delivers a continuous standstill torque of 38.0 Nm, providing static holding capability without thermal overload. The enclosure meets IP65, which prevents dust ingress and resists low-pressure water jets during washdown. Heat is removed through liquid cooling, so the motor can maintain full torque in tightly packed installations. A square mounting flange of 192 mm and a centering diameter of 130 mm help align the frame accurately to gearboxes or machine plates. Position feedback is supplied by an optically scanned digital servo feedback encoder that reports relative rotor angle to the drive, while the plain shaft couples directly to couplings or belt pulleys.

The integrated holding brake supplies 70.0 Nm of static torque to secure vertical or safety-critical axes when power is removed. System accuracy remains within ± 0.5 arcminutes, which supports repeatable motion profiles during controlled positioning. The motor operates in ambient temperatures from 0 to 40 °C and uses Class F insulation to protect the windings against heat. It also has a shaft seal, stores safely from -20 to +80 °C, and receives power through an output connector on side B. Installation is permitted up to 1000 m above mean sea level, while length code C, winding code 058, and frame size 112 identify the motor's coil set and magnetic geometry for the required speed-torque curve.
