MHD115C-059-NG0-AA

The Bosch Rexroth Indramat MHD115C-059-NG0-AA servo motor is a high-precision actuator within the MHD Synchronous Motors series, engineered for demanding industrial applications. Manufactured by Bosch Rexroth Indramat, this product type: Servo Motor features digital encoder feedback and delivers exceptional dynamic response. It achieves a continuous torque output of Continuous Torque at Standstill 70.0 Nm and exhibits favorable torque-to-inertia characteristics for rapid acceleration. Designed as a plain shaft unit without a holding brake, it provides friction-locked hub connection with minimal play and high running smoothness. The motor’s robust construction and integrated data memory enable a straightforward startup sequence and reliable performance under fluctuating loads.

The motor’s mechanical and electrical parameters are precisely defined to support rigorous control systems. It incorporates Winding Code 059 and a Motor Size 115, while the physical envelope is defined by a Centering diameter 180 mm and a Flange size 192 mm. The Motor Length C designation corresponds to optimized winding dimensions for efficient heat dissipation. Power is delivered through an Output Connector arranged Power Connection Direction to side A. The device employs <> Encoder Type Digital servo feedback (HSF) with system accuracy of ±0.5 angular minutes and uses Type of Position Detection Relative to streamline motion control. Cooling is provided by Housing Cooling Type Natural convection, eliminating the need for external cooling circuits, and the motor sealing ring is resistant to oils and chemicals.

Operationally, the MHD115C-059-NG0-AA is a fully enclosed design rated for storage and transport between –20 °C and +80 °C, with reliable functionality up to an elevation of 1000 m above sea level. It can be mounted horizontally or vertically, provided there is no liquid ingress around the shaft when oriented upward. The Shaft Design Plain shaft is fitted with a Shaft Seal Yes that protects internal components and maintains high overload capacity by ensuring efficient thermal conduction between stator windings and the housing exterior. Integrated temperature monitoring safeguards against thermal overload, while electronic commutation delivers peak torque across a wide speed range. The unit’s natural convection cooling supports sustained operation without auxiliary fans, and the simple cabling arrangement expedites installation and maintenance.

System integration is facilitated through compatibility with standard industrial drives and controllers, allowing seamless incorporation into multi-axis systems. The absence of a holding brake simplifies mechanical design and reduces maintenance requirements. Ideal target applications include precision assembly, robotics, CNC machinery, and high-speed packaging equipment, where the combination of high continuous torque, rapid dynamic response, and precise encoder feedback are critical success factors. Bosch Rexroth Indramat’s quality assurance and one-year warranty tag further ensure reliable long-term operation in industrial automation environments.
