Product Description:

The MHD115B-059-PP1-AA belongs to the MHD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is a servo motor intended for closed-loop industrial automation where precise rotary motion must be coupled directly to drive controllers. Its synchronous design supports accurate torque and speed regulation for positioning, transfer, and indexing tasks in automated equipment. The unit’s B-length mechanical frame and size 115 stator package provide high torque density without forced cooling, making the motor suitable for packaging lines, gantry axes, and general material-handling tasks.

The motor can deliver a continuous standstill torque of 50.0 Nm, giving machinery enough static force to hold or slowly accelerate loads without overheating. Thermal energy is removed by natural convection, so no fan or liquid circuit is required and enclosure layouts remain simpler. Accurate centering during installation is aided by a 180 mm centering diameter, while the square mounting interface uses a 192 mm flange size that matches standardized machine plates. A keyed shaft transmits torque through positive mechanical engagement, which helps prevent slippage during startup and repeated direction changes. Power enters the stator windings through an output connector on side A, allowing cable routing to follow cabinet layouts without sharp bends.

Position retention during power loss is handled by a holding brake that produces 70.0 Nm of static torque, which is useful on vertical axes and other loads that must remain fixed at a stop. Rotor position is reported by digital servo feedback with integrated encoder, and the system uses absolute position detection beyond 4096 revolutions, allowing a compatible control to recover axis position after an interruption. A shaft seal is fitted to help block dust and oil ingress, supporting use in mildly dirty environments. The feedback system also allows the drive to resume operation with position data already available after power is restored.
