MHD115A-058-PP0-BA
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD115A-058-PP0-BA from the MHD Synchronous Motors series delivers precision motion control with a motor size of 115 and a compact motor length A frame that fits tight cabinet layouts. This servo motor is equipped with digital servo feedback with integrated encoder and provides absolute position detection for over 4096 revolutions, ensuring repeatable accuracy in demanding applications. Designed without a holding brake, it relies on natural convection housing cooling to dissipate heat efficiently under continuous operation. Power connectivity is streamlined via an output connector, routed neatly to side B, reducing installation time and simplifying cable management.
Built for robust industrial environments, the MHD115A-058-PP0-BA delivers a continuous torque at standstill of 32.0 Nm and features a precision keyed shaft design with integrated shaft seal to prevent contamination. Its flange size of 192 mm and centering diameter of 180 mm ensure straightforward mechanical integration with gearboxes, couplings, and mounting surfaces. The winding code 058 offers consistent thermal performance and repeatable torque curves across production units. The motor’s encoder offers closed-loop control for high-speed servo applications while maintaining a compact footprint.
Installation and maintenance are simplified by the motor’s rugged construction and standardized dimensions. Its natural convection cooling eliminates the need for external fans, reducing noise and potential points of failure. The result is a high-performance servo solution ready for packaging machines, robotics, and precision assembly lines requiring reliable, low-maintenance operation.

Frequently Asked Questions
What installation advantage does the output connector on side B provide?
The side B output connector allows clean cable routing in compact layouts. The arrangement simplifies maintenance and shortens installation time in control cabinets.
How does the absence of a holding brake influence system design?
The lack of a holding brake requires external mechanical restraint when power is off. The design reduces weight and inertia improving dynamic motion response.
What effect does the winding code 058 have on performance consistency?
The winding code 058 standardizes thermal and torque behavior across units. The uniform winding characteristics simplify drive parameter setup and system tuning.
How does the encoder support performance in multi axis synchronization?
The encoder delivers precise position feedback that enables tight synchronization between axes. The feedback stability ensures minimal phase lag during coordinated motion.
Why is the centering diameter important for mechanical alignment?
The centering diameter guarantees accurate alignment with attached gearboxes and fixtures. The correct fit minimizes vibration and prevents shaft misalignment during operation.
