Product Description:

The MHD112A-024-PP1-AN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It converts commanded current from a drive controller into controlled mechanical torque for positioning tables, gantry axes, and automatic tool changers that require repeatable motion. A built-in absolute encoder sends rotor position data to the drive for closed-loop control. The housing is prepared for a coolant circuit, which helps the motor maintain output in applications where surrounding airflow is limited. This arrangement supports accurate starts, stops, and holding behavior during cyclic machine operation.

The motor provides a continuous standstill torque of 15.0 Nm, which allows it to support stationary loads without excessive heat rise. Its mounting face uses a 192 mm flange, while the centering shoulder measures 130 mm for accurate alignment in the mating machine surface. Heat is removed through liquid cooling, which improves thermal dissipation when compared with surface ventilation alone. Electrical behavior is set by winding code 024, which matches the motor to the correct current settings in a compatible drive. These features make the motor suitable for machine layouts that need stable torque and reliable thermal performance.

An electromechanical brake rated at 22.0 Nm clamps the shaft when drive torque is disabled, helping suspended or vertical loads remain in place during a power interruption. The feedback system retains absolute position over more than 4096 revolutions, so the axis can restart without a homing cycle after shutdown. Power leads terminate at an output connector positioned on side A, which can simplify cable routing when the motor is installed near a panel wall. The motor also uses a keyed shaft and a shaft seal to support direct torque transfer while limiting the entry of contaminants. Its A-length housing keeps the package compact for installations where available motor space is limited.
