MHD115A-024-NG0-AA
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD115A-024-NG0-AA from the MHD Synchronous Motors series is a high-precision Product Type: Servo Motor designed for demanding automation tasks. It features a Motor Size 115 frame with Motor Length A, delivering a Continuous Torque at Standstill of 32.0 Nm for reliable holding and low-speed control. Position feedback is provided by a Digital servo feedback (HSF) Encoder Type with Type of Position Detection Relative, ensuring repeatable accuracy in incremental moves. The Winding Code 024 and Plain shaft Shaft Design combine for robust mechanical integrity and simplified mounting.
Cooling and environmental resilience are built into the MHD115A-024-NG0-AA with a Housing Cooling Type Natural convection system that eliminates moving parts and reduces maintenance. A Shaft Seal: Yes and a centering diameter of 180 mm paired with a Flange size 192 mm deliver precise alignment and ingress protection for the rotor assembly. The unit is specified Without holding brake, reducing overall mass and inertia when external brakes are preferred. Power is routed through an Output Connector with a Power Connection Direction to side A, streamlining cable runs in tight cabinet layouts.
Engineers benefit from the MHD115A’s compact dimensions, precise feedback, and passive cooling, making it ideal for pick-and-place systems, rotary tables, and synchronous conveyor setups. Its relative position detection and 32.0 Nm standstill torque ensure stable performance under transient loads. The combination of digital feedback, sealed shaft, and side-A power connection delivers a low-maintenance, high-availability solution for modern machine designs.

Frequently Asked Questions
What determines the torque capability of MHD115A-024-NG0-AA?
The continuous torque capability depends on the cooling method and winding configuration. The torque increases with enhanced cooling efficiency, enabling higher sustained load performance under industrial conditions.
How does the winding inductivity affect servo performance?
The winding inductivity of 8.6 mH influences current response and control stability. The higher inductance smooths current transitions, minimizing torque ripple and improving servo precision.
What is the role of voltage constant Ke in operation?
The voltage constant of 150 V/1000 min⁻¹ defines the motor’s back EMF characteristics. The precise value ensures optimal speed-torque conversion and predictable drive matching.
How do thermal ratings impact continuous current limits?
The thermal ratings at 60 K and 100 K dictate permissible continuous current. The increased temperature margin enables greater torque delivery without thermal degradation.
Why is the rotor moment of inertia important?
The rotor inertia of 6.5 × 10⁻³ kgm² affects acceleration and deceleration response. The balanced inertia supports accurate motion control and smooth dynamic load transitions.
