Product Description:
The MHD112B-035-PP2-AN is a servo motor manufactured by Bosch Rexroth Indramat and placed in the MHD Synchronous Motors series. It delivers precisely regulated rotary motion for automated packaging lines, machine tools, and material-handling stations. Identification features include motor size 112, length code B, a keyed shaft, and an output connector that routes the power cable to side A. The combination of the shaft layout, connector orientation, and integrated feedback suits direct installation on servo-driven machine axes. Position data are returned through a digital servo feedback encoder that is integrated into the housing.
It delivers a continuous standstill torque of 28.0 Nm, allowing the axis to hold a load without drift. A built-in holding brake supplies 32.0 Nm of static torque so vertical axes remain locked when power is removed. The enclosure carries a IP65 rating and is fitted with a shaft seal, providing total dust exclusion and resistance to water jets. Heat is removed through liquid cooling, keeping the windings within the F-class insulation limits during sustained duty. The unit operates reliably between 0 to 40 °C, while it can be stored from −20 to +80 °C without degradation. Optical measurement inside the encoder supports digital servo feedback and contributes to the high positioning precision demanded by automated cells.
The mechanical interface uses a centering diameter of 130 mm and a flange square measuring 192 mm. These dimensions let the motor seat directly on standard machine frames without alignment sleeves. Position feedback has a system accuracy of ± 0.5 angular minutes, and the absolute encoder supports more than 4096 revolutions, eliminating the need for homing after power restoration. Winding code 035 matches the electrical constants expected by the drive controller, and installation is permissible up to 1000 m above mean sea level. All measurements reference the optical method used by the feedback system.
