Product Description:

The MHD112C-035-NG3-LN is a servo motor manufactured by Bosch Rexroth Indramat for the MHD Synchronous Motors series. It serves as a rotary actuator in automated production lines, supplying controlled motion to positioning tables, packaging stations, and processing heads that require stable speed control and accurate feedback. Position feedback comes from a Digital servo feedback (HSF) encoder that is read optically, giving the drive fast rotor data during closed-loop operation. This feedback arrangement helps the connected drive correct speed variation and maintain controlled motion during indexing and positioning tasks.

The motor delivers a continuous standstill torque of 38.0 Nm, and its integrated brake can secure loads with up to 70.0 Nm when power is removed. An enclosure rating of IP65 protects the stator windings and bearings against dust and low-pressure water jets, and the housing uses liquid cooling to limit thermal rise during constant duty. A flange circle of 192 mm works with the 130 mm centering diameter for rigid mounting to machine frames. The motor has a plain shaft with a shaft seal to support direct coupling, and electrical power enters through a connector on the left side. The sealed shaft end helps keep contaminants away from the bearing area during coolant-exposed operation. Its Class F insulation system supports winding temperatures associated with an operating ambient range of 0 to 40 °C.

Long-term storage is allowed between -20 to +80 °C, and the unit may be installed up to 1000 m above sea level without derating. Closed-loop accuracy is held within ± 0.5 angular minutes through the relative position detection method and the high-speed encoder. The motor uses a 112-frame stator with length code C and winding code 035. This combination matches the size and winding arrangement used for this model. Relative position detection allows the drive to track shaft movement precisely during speed changes and short positioning moves.
