MHD115A-058-NG0-AN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD115A-058-NG0-AN is a precision Servo Motor from the MHD Synchronous Motors series featuring a Winding Code 058 and a Motor Size 115 frame. This Plain shaft motor includes an integrated Digital servo feedback (HSF) encoder for high-resolution position detection. Designed with Liquid cooling for sustained duty, the unit supports Relative position detection without external encoders. Power is delivered through an Output Connector directed to side A, ensuring streamlined installation and serviceability.
Constructed with a compact Motor Length A housing, the MHD115A-058-NG0-AN delivers a continuous torque at standstill of 32.0 Nm. Precision alignment is provided by a Centering diameter 180 mm and a robust Flange size 192 mm, while the sealed construction features a Shaft Seal for enhanced protection. With no integrated holding brake (Without holding brake), the motor achieves a lightweight design optimized for dynamic applications. This configuration ensures stable performance at rated speeds and simplifies integration into existing machine-tool assemblies.
Engineered as a maintenance-free permanent magnet unit, the MHD115A-058-NG0-AN guarantees reliable operation in automation, handling, and food processing equipment. Absence of a holding brake reduces complexity, while the built-in digital encoder supports precise closed-loop control. This servo motor’s combination of compact dimensions, liquid cooling capability, and high-torque density makes it an ideal choice for demanding industrial environments.

Frequently Asked Questions
Why is a plain shaft design preferred in some automation setups?
The plain shaft allows flexible coupling options and easier integration into direct-drive systems. It is ideal for applications where backlash elimination and alignment precision are critical.
How does the compact housing length affect machine tool integration?
The reduced housing length enables installation in tight enclosures or retrofit scenarios. It helps maximize workspace while maintaining required torque output.
What does the centering diameter contribute to during motor mounting?
The centering diameter ensures accurate motor alignment on the mounting flange. This improves load balancing and minimizes shaft runout under rotational stress.
How does the digital HSF encoder improve motion accuracy?
The high-resolution feedback supports fine position control and consistent velocity regulation. This enhances process precision, especially in CNC and robotic applications.
What installation benefits come from having the power connector on side A?
The fixed output connector orientation simplifies cable routing and access during servicing. It reduces installation variability and ensures repeatable electrical connections.
