Product Description:

The MHD115B-024-PG1-AA servo motor is a Bosch Rexroth Indramat unit in the MHD Synchronous Motors series. Intended for industrial automation, it converts regulated electrical energy from a drive controller into controlled mechanical rotation for positioning and velocity tasks on gantries, packaging machines, and material-handling axes. A digital servo feedback unit is built into the motor housing so the controller receives immediate rotor position data without separate external transducers. That feedback helps the drive correct deviations caused by changing load conditions and maintain accurate response during repeated cycles. The motor is suited for axes that need both smooth speed regulation and repeatable positioning over long production runs.

A centering diameter of 180 mm aligns the motor with a matched machine flange, while a face diameter of 192 mm establishes the front mounting footprint. Heat produced in the windings is removed by natural convection, so no external blower or coolant circuit is required. At standstill, the motor can deliver 50.0 Nm of continuous torque for holding and low-speed load control. Power leads exit on side A, which can simplify cable routing when the drive cabinet is positioned along the same side of the machine. Because cooling is passive, surrounding airflow and mounting clearance play an important role in continuous operation. The mounting geometry also supports accurate alignment between the motor and connected mechanical components.

An integrated brake provides 70.0 Nm of static torque to hold the axis when power is removed. This is useful where the load must remain stationary between moves or during a power interruption. The motor uses a plain shaft with a factory-installed seal to help limit lubricant migration and protect the bearing area from contamination. Absolute feedback resolution is listed as absolute (>4096 revolutions), so the controller can retain multi-turn position information through normal operating cycles. Winding code 024 matches the drive voltage table, and the B length in the 115 frame gives the motor a balanced combination of inertia and torque capacity for medium-load applications. The power interface uses an output connector for direct cable attachment and orderly routing at the motor housing.
