Product Description:
The MHD112B-024-NP0-RN is a servo motor built by Bosch Rexroth Indramat and positioned within the MHD Synchronous Motors series. As a closed-loop actuator, it converts drive commands into controlled rotary motion for indexing tables, gantry axes, and other automation stages where precise velocity and position are required. It integrates seamlessly with IndraDrive controllers to deliver rapid acceleration and precise electronic gearing in compact industrial machinery.
At standstill, the rotor can deliver a continuous torque of 28.0 Nm, allowing the axis to hold load without overheating during static positioning cycles. A centering diameter of 130 mm and a flange size of 192 mm match common IEC and ISO mechanical interfaces, simplifying direct mounting to gearboxes or frames. The motor has an IP65 rating, which shields internal components from dust ingress and low-pressure water jets, so enclosure sealing is adequate for washdown areas. Heat generated by the stator is transferred to a coolant circuit through liquid cooling, which supports sustained overload without relying on ambient airflow. Because the motor is supplied without a holding brake, external clamping or drive-based torque must secure vertical or overhung loads during power loss.
The unit employs Digital servo feedback (HSF) with an optical measurement path that reports relative position data to the drive. This configuration achieves a system accuracy of ±0.5 angular minutes, which is adequate for fine contour machining or coordinated axis control. A keyed shaft transmits torque positively, and a shaft seal keeps lubricant and coolant from entering the housing. Rated duty is possible from 0 to 40 °C, while storage from -20 to +80 °C avoids condensation damage. Class F insulation expands the thermal margin, and winding code 024 sets the electromagnetic constants for the size 112, length B stator. Installation height is limited to 1000 m above sea level, and a right-side power connector streamlines cable routing inside compact cabinets.
