Product Description:

The MHD115B-024-PG1-AN is a servo motor manufactured by Bosch Rexroth Indramat within the MHD Synchronous Motors series. Designed for industrial automation, it delivers controlled rotary motion for feed drives, pick-and-place heads, and other CNC axes where closed-loop precision is required. Its permanent-magnet rotor and integrated position electronics place motion generation and feedback in one housing, which helps keep the machine layout compact. When paired with compatible Indramat digital controllers, the motor supports programmable acceleration profiles and continuous position monitoring during dynamic axis movement.

Mechanical output is governed by a continuous standstill torque of 50.0 Nm, allowing the axis to resist load at zero speed without overheating under rated conditions. When power is removed, the integral holding brake applies 70.0 Nm of static torque to secure the shaft in place. A centering diameter of 180 mm aligns the motor with precision housings, while the 192 mm square flange provides a standardized mounting surface for rigid installation. Heat from the stator is removed by liquid cooling channels in the housing, and power and feedback cabling exit toward side A to support straightforward routing inside the machine.

The integrated digital servo feedback encoder supplies absolute feedback for more than 4096 revolutions to the drive controller, so axis position remains available across repeated turns without requiring a separate external transducer. Its plain shaft, machined without a keyway, is fitted with a shaft seal to help limit lubricant or coolant ingress at the output end. Electrical behavior follows winding code 024, which matches the motor to compatible drive settings and supports the B-length rotor stack used for this frame size. This arrangement supports accurate indexing and stable velocity control in packaging, transfer, and gantry applications.
