Product Description:

The MHD112D-027-PP3-BN is a servo motor built by Bosch Rexroth Indramat and assigned to the MHD Synchronous Motors series. It is intended for precision industrial automation where rapid, repeatable rotary motion must be synchronized with a controller. The integrated digital servo feedback encoder supplies real-time position and speed data to the drive, enabling tight closed-loop control. The motor serves as a direct mechanical interface for CNC axes, packaging stations, or material-handling gantries that rely on high stall torque and fast response without excessive installation space.

The 112 frame size uses a D-length stator that increases heat-dissipating surface area while keeping installation depth moderate. A centering pilot of 130 mm seats the motor concentrically inside the machine bore, and the flange spreads to 192 mm to distribute clamping forces. The electromagnetic package sustains 48.0 Nm of continuous standstill torque, so the drive maintains force without overheating. Thermal energy is removed by liquid cooling, which circulates coolant through the housing jacket to stabilize winding temperature during continuous duty. Torque is transmitted through a keyed shaft, whose positive engagement helps prevent slippage during sudden reversals. A shaft seal is fitted to protect the front bearing against coolant splash and fine particulates.

Additional design elements address load holding, feedback retention, and drive matching. A built-in brake supplies 70.0 Nm of static torque to secure parked loads. Power is fed through an output connector on side B, which can help reduce cable loops on linear slides and other compact machine sections. The position transducer provides absolute feedback for more than 4096 revolutions, keeping the controller aware of rotor angle even after a loss of power. The 027 winding matches the electrical characteristics expected by compatible Indramat converters for stable current regulation during dynamic cycles.
