MHD115A-058-NG0-AA
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD115A-058-NG0-AA servo motor from the MHD Synchronous Motors series features an 058 winding code and delivers a continuous torque at standstill of 32.0 Nm with a theoretical maximum torque of 110 Nm. It incorporates Digital servo feedback (HSF) encoder and relative position detection, with a plain shaft design and shaft seal ensuring reliable operation. The natural convection cooling housing and Motor length A construction optimize heat dissipation, while the flange size 192 mm and centering diameter 180 mm facilitate quick mounting. With a moment of inertia 65 x 10^-4 kgm2 and a power connection directed to side A via an output connector, this unit provides high dynamics, overload capability and easy machine integration.

Frequently Asked Questions
What are the installation benefits of the plain shaft design in this servo motor?
The plain shaft simplifies alignment with coupling systems and minimizes mechanical complexity. The absence of a keyway reduces vibration risks in high-speed applications.
How does the shaft seal improve performance in industrial environments?
The shaft seal protects internal components from dust and moisture intrusion. The added sealing extends motor life and reduces unplanned maintenance.
What effect does the motor’s moment of inertia have on motion control?
The relatively high moment of inertia supports smoother acceleration and deceleration. The inertia value enhances control in applications with frequent load changes.
How does natural convection cooling impact thermal management in enclosed spaces?
The natural convection housing relies on ambient airflow which limits cooling performance in tight spaces. The design is best suited for environments with sufficient air circulation around the motor.
Why is relative position detection significant in closed-loop feedback systems?
The encoder’s relative feedback allows for fast position tracking during operation. The system requires a homing routine at startup to establish an absolute reference.
