Product Description:
The MHD112B-058-PP0-AN is a three-phase servo motor produced by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Designed for tightly regulated motion in industrial machines, it supplies commanded torque and speed to feed drives, gantry axes, and material-handling stations. The electromagnetic winding uses code 058 and is matched to common drive combinations for responsive acceleration in general automation duty. Its B length and 112 frame size give the motor a moderate inertia profile that suits mid-range loads.
The centering pilot measures 130 mm in diameter, and the square flange measures 192 mm. A keyed shaft transmits drive power while an integral shaft seal helps block coolant and dust from entering the housing. For continuous load, the motor can provide 28.0 Nm of standstill torque, and heat is removed through a liquid cooling jacket that helps keep winding temperature within the Class F limit. The housing is rated IP65, which protects against dust ingress and water jets during washdown cleaning. Electrical power enters from side A through an output connector, and the motor is supplied without a holding brake for applications that rely on external locking hardware or drive-controlled holding torque.
Position feedback is provided by an optical digital encoder with Absolute (>4096 revolutions) capability, and this arrangement supports repeatable positioning after multiple shaft turns. The feedback system has an accuracy of ± 0.5 angular minutes, which supports fine contouring and consistent indexing performance. The motor can operate continuously in ambient air from 0 to 40 °C, and it can be stored between -20 to +80 °C. Installation altitude is limited to 1000 m above sea level so the cooling system can operate as intended, and the Class F insulation system supports a thermal ceiling of 155 °C at the winding.
