MHD115A-058-NP1-AA
MHD Synchronous Motors
MHD115A-058-NP1-AA, Bosch Rexroth Indramat, MHD Synchronous Motors. This Servo Motor in the MHD Series features a robust Motor Size 115 design with a Flange size of 192 mm and a Centering diameter of 180 mm. Engineered for flexibility, the unit employs a Keyed Shaft with an integrated Shaft Seal to protect against contaminants. A compact Motor Length A profile ensures compatibility with space-constrained installations.
The motor delivers a Continuous Torque at Standstill of 32.0 Nm and integrates a With holding brake system offering a Holding Brake Torque of 70.0 Nm for static load retention. Temperature management is handled by Natural convection Housing Cooling Type, eliminating fan maintenance and reducing acoustic emissions. Position feedback is provided by a Digital servo feedback (HSF) Encoder Type with Relative Type of Position Detection, enabling high-resolution control. Power is supplied via an Output Connector Power Connection Type oriented to side A for streamlined cabling, and the Winding Code 058 optimizes thermal performance under dynamic loads.
Designed for seamless integration, the MHD115A-058-NP1-AA mates directly with standard drive controllers, simplifying commissioning and reducing wiring complexity. Its rugged sealed housing and precision encoder deliver dependable operation in demanding automation environments. The combination of high brake torque, efficient passive cooling, and precise feedback ensures reliable, low-maintenance performance across high-duty-cycle applications.

Frequently Asked Questions
Why is natural convection cooling advantageous for maintenance-sensitive environments?
The system removes heat without a fan which avoids extra parts and noise. The design also limits dust buildup improving reliability over time.
How does the digital servo feedback encoder enhance motion precision?
The encoder sends high-resolution feedback to the drive system. The signal allows fast corrections that improve path accuracy and repeatability.
What is the function of the holding brake in maintaining system safety?
The holding brake keeps the motor shaft fixed when power is off. The feature prevents unwanted motion in vertical or suspended axes.
How does the flange and centering diameter simplify motor alignment?
The precise geometry ensures a tight mechanical fit with the machine mount. The alignment minimizes vibration and improves bearing life.
What installation precautions are needed when using natural convection cooling?
The motor must be installed with enough space for air movement. The area should stay clean and free from nearby heat sources.
