MHD115C-059-NP0-AA

The Bosch Rexroth Indramat MHD115C-059-NP0-AA synchronous motor from the MHD Synchronous Motors series delivers a compelling combination of compact design and precision control for high-performance automation systems. Featuring a Digital servo feedback (HSF) encoder and a Type of Position Detection Relative, it provides accurate speed and position monitoring with a system accuracy of ±0.5 angular minutes. The model’s low-inertia rotor design ensures rapid dynamic response and favorable torque-to-inertia ratio, enabling smooth acceleration and deceleration in demanding applications. With its keyed shaft design and grease-lubricated bearings, the MHD115C-059-NP0-AA operates reliably without the need for regular relubrication. Its design omits a holding brake, maintaining a simplified mechanical configuration and reducing overall system complexity.

The motor’s precise mechanical interfaces facilitate straightforward integration: it features a Centering diameter of 180 mm and a Flange size of 192 mm matched to a Motor Size of 115 frame. The Motor Length C designation reflects the mid-length variant in the MHD series, while the Winding Code 059 specifies the winding configuration optimized for continuous torque delivery. At standstill, the motor provides Continuous Torque at Standstill of 70.0 Nm, supporting high load-holding capacity. The Power Connection Direction to side A and Power Connection Type Output Connector enable modular cabling using standard Rexroth power and encoder cable sets. Complete sealing is assured by the integrated Shaft Seal Yes feature, preserving internal components against contaminants.

Designed for robust operation in industrial environments, the MHD115C-059-NP0-AA employs Housing Cooling Type Natural convection and surface cooling to dissipate heat effectively under continuous load. Its fully closed housing with Ingress Protection rating of IP65 resists dust and water ingress, while an integrated temperature sensor prevents damage from thermal overload. Bearings are grease-lubricated for their entire service life and rated for a service life of 30,000 operating hours when operated within recommended radial and axial load limits. The servo feedback system’s onboard data memory retains motor parameters, enabling rapid startup without external parameter downloads and reducing commissioning time.

System integration is streamlined through compatibility with Bosch Rexroth digital intelligent drive controllers, enabling advanced motion control features such as real-time tuning, vibration suppression, and predictive maintenance diagnostics. The relative position detection and high-resolution encoder make the MHD115C-059-NP0-AA ideally suited for precision tasks in machine tools, paper and printing machinery, handling and automation systems, and food processing and packaging equipment. As part of the MHD Synchronous Motors series, this motor model meets the rigorous demands of modern manufacturing, delivering reliable performance, easy integration, and low maintenance overhead.
