Product Description:
The MHD112C-024-NP0-RN belongs to the MHD Synchronous Motors series produced by Bosch Rexroth Indramat. It is a three-phase servo motor intended for closed-loop industrial positioning tasks that require constant torque and quick dynamic response. The unit converts commanded current into precise rotary motion for servo-driven axes in automated machinery. It combines motor size 112 with length C and uses winding code 024 to match standard Indramat drive controllers used in modular machine platforms.
The motor can deliver a continuous standstill torque of 38.0 Nm, allowing the axis to hold a sustained load during rated operation without overheating. Thermal energy is removed through liquid cooling, so full torque remains available even in sealed cabinets. The housing is sealed to IP65, which helps keep dust and low-pressure water jets away from internal components. A flange diameter of 192 mm and a centering pilot of 130 mm support accurate and repeatable mounting. The motor uses a keyed shaft with a shaft seal, and power is routed through a right-hand power connector to simplify cable routing. Because the motor does not include a holding brake, the axis must rely on drive torque or an external lock to hold a static load.
The permitted operating ambient temperature range is 0 to 40 °C, and storage is allowed from -20 to +80 °C. Installation is permitted up to 1000 m above mean sea level. Motion feedback is provided by digital servo feedback (HSF), and its optical measurement method with relative position detection supports a system accuracy of ± 0.5 angular minutes. This feedback arrangement gives the drive the rotor position data needed for speed and position control during operation. Insulation built to Class F supports winding temperatures up to 155 °C when cooling flow is briefly reduced.
