Product Description:

The MHD112C-035-NP0-AN is a servo motor produced by Bosch Rexroth Indramat in the MHD Synchronous Motors series. Designed for closed-loop industrial automation, it converts drive current into regulated rotary motion for positioning, conveying, and process equipment. Its keyed output shaft integrates with couplings or pulleys, and the 112-frame housing fits machines where space is limited.

At standstill, the motor delivers a continuous torque of 38.0 Nm, allowing heavy loads without excess current. A centering diameter of 130 mm aligns the housing to the machine plate, and the 192 mm flange provides four-bolt mounting for secure attachment. Heat is removed through liquid cooling, which stabilizes winding temperature during high-duty operation. The motor is sealed to IP65, which helps protect the bearings and stator from dust and water jets. A keyed shaft with an integral shaft seal helps prevent slip and lubricant loss, and the power leads exit on side A through an output connector to keep wiring orderly. Because the motor is supplied without a holding brake, any static holding force must be provided by the drive or by external mechanics. The motor has frame size 112, motor length C, and winding code 035.

Position control is handled by a digital servo feedback (HSF) encoder that uses an optical measurement method and provides a system accuracy of ± 0.5 angular minutes. The feedback is relative, so an external homing routine is required after power-up. The winding uses Class F insulation for thermal durability during repeated cycling. The motor operates in ambient temperatures from 0 to 40 °C, and storage is permitted from -20 to +80 °C without damage. Operation is allowed up to 1000 m above mean sea level, and a positive shaft seal helps keep coolant or washdown fluids out of the stator cavity.
