The Bosch Rexroth Indramat MKD112C-058-GP3-BN is a high-performance component in the MKD Synchronous Motors series, engineered for precise motion control in demanding industrial applications. As a 3-phase synchronous servo motor with a rated speed of 3000 RPM and a maximum speed of 6000 RPM, it delivers consistent dynamic response and high accuracy. Equipped with a shaft with keyway and flange mounting, this unit integrates seamlessly into automated systems, providing robust mechanical coupling and secure attachment. With a holding brake offering a 70 Nm holding torque, the motor ensures safe standstill positioning and load retention under all operating conditions.



Within this model, the continuous torque at standstill of 38.0 Nm underlines its capability to sustain high loads without motion, while the resolver feedback (RSF) encoder type ensures reliable position detection in relative mode. The C-length motor features a centering diameter of 130 mm and a flange size of 192 mm, optimizing installation flexibility and alignment accuracy. The motor’s output connector allows for rapid electrical connection, and its synchronous design guarantees smooth torque delivery across the entire speed range. The 058 winding code emphasizes a tailored coil arrangement for efficient thermal management and consistent performance.



Designed for durability and maintenance simplicity, the MKD112C-058-GP3-BN employs a sealed shaft to protect internal components and extend service life. Compatibility with standard flange interfaces and its versatile mounting type make it suitable for retrofit or new installations in packaging, robotics, and CNC machinery. The integrated holding brake enhances safety by preventing unwanted motion during power loss or emergency stops. Energy-efficient operation and low vibration levels minimize heat generation, promoting longer operating cycles and reduced cooling requirements. In industrial settings where precision, reliability, and uptime are critical, this servo motor offers streamlined integration and superior control for optimal productivity.

How does the 70 Nm holding brake on the MKD112C-058-GP3-BN maintain axial stability during power loss or an E-stop?

Its electrically released brake applies clamping torque when de-energized to prevent back-driving on vertical or suspended loads. Its 70 Nm rating provides substantial static holding margin for fine-pitch ball-screws and belt transmissions to improve stop-state determinism and restart repeatability.

How do the 192 mm flange and 130 mm centering diameter of the MKD112C-058-GP3-BN influence mounting accuracy and rotor–load concentricity?

The large pilot and bolt circle minimize eccentricity and simplify coaxial alignment for reducing radial load on bearings. Its correctly toleranced locating fit improves coupling balance at speed to lower vibration and enhances interpolation quality on precision axes.

Why is the MKD112C motor’s 38.0 Nm continuous torque at standstill relevant for indexers and dwell-heavy profiles?

The continuous static torque allows sustained holding without thermal runaway during long dwells or clamp cycles. It supports aggressive S-curve profiles where average speed is low but high static torque is repeatedly demanded.

How does a sealed output shaft contribute to reliability on the MKD112C-058-GP3-BN in washdown-adjacent or dusty cells?

The shaft seal mitigates ingress of contaminants and lubricant egress to preserve bearing life and insulation integrity. It reduces maintenance intervals in environments with atomized coolants, paper dust or packaging particulates.

What tuning and bearing-load considerations arise from 3000 rpm rated and 6000 rpm maximum speed on the MKD112C-058-GP3-BN?

The servo gains follows mechanical resonance and back-EMF near the upper speed region to avoid saturation. Its bearing preload and coupling balance become increasingly critical above rated speed to control heat and axial growth.
