Product Description:
The MHD112D-012 is a synchronous motor supplied by Bosch Rexroth Indramat under the MHD Synchronous Motors series. Intended for industrial automation, the unit acts as an electromechanical actuator that delivers commanded speed and position feedback to numerical controls and motion controllers. By translating drive current into rotor torque without slip, it supports precise axis regulation in machining centers, material-handling equipment, and general-purpose assembly lines. Its stator windings are selected through coded variations so the motor can be matched to a compatible drive module.
A centering pilot of 130 mm aligns the housing to the machine plate and helps keep runout low. The rectangular mounting face has a 192 mm square flange, which gives the shaft solid support for belt pulleys or gear couplings commonly used on this frame size. Frame designation 112 identifies the stator outer diameter used for this motor size. Coil variant 012 sets the winding impedance and back EMF profile so the drive can reach rated speed without excessive current. These dimensions and winding characteristics support consistent installation and electrical matching in motion systems. The motor is produced by Bosch Rexroth Indramat.
The motor provides a continuous stall torque of 48.0 Nm, so the axis can hold heavy tables or press rams at zero speed without an external brake. Length code D indicates an extended active stack that increases thermal mass and torque capability compared with shorter versions in the same frame size. Within the MHD Synchronous Motors series, this model serves applications that need a larger motor package than shorter units in the same platform. As a Servo Motor, it responds to fine current commands from digital drives and supports smooth low-speed interpolation during controlled motion.
