MKD112C-058-KP0-BN
MKD Synchronous Motors
The Bosch Rexroth Indramat MKD112C-058-KP0-BN servo motor is a high-performance product in the MKD Synchronous Motors series, designed for precision motion control in demanding industrial applications. With a robust continuous torque at standstill of 38.0 Nm and a flange size of 192 mm, this motor delivers exceptional starting and holding capabilities. Its primary function is to provide accurate positioning and dynamic response in automation systems, ensuring consistent operation across diverse production environments.
Featuring a resolver feedback with integrated encoder and absolute position detection (over 4096 revolutions), the MKD112C-058-KP0-BN offers precise feedback for high-resolution control. The shaft is designed with a keyway and a reliable shaft seal, enabling secure coupling and protection against contaminants. The motor’s motor length C and centering diameter of 130 mm provide a compact footprint, while the winding code 058 ensures optimized electrical performance. Cooling is achieved through a standard method that balances thermal management with structural simplicity.
This servo motor is equipped with lifetime lubricated bearings and a brushless, maintenance-free design, contributing to an estimated lifespan of 10 years under regular use. It operates without a holding brake, offering flexibility in system integration and higher efficiency by eliminating brake-related energy losses. The output connector supports multiple power connection directions, simplifying installation and cabling in complex assemblies. With its combination of durability, precision feedback, and long service life, the MKD112C-058-KP0-BN is ideally suited for continuous-duty industrial tasks, minimizing downtime and maximizing throughput.

Frequently Asked Questions
How do the 192 mm flange and 130 mm centering diameter influence alignment tolerance and dynamic accuracy in gantry or spindle applications?
The pilot (centering) diameter defines concentricity, its accurate fit reduces eccentricity-induced runout that stabilizes servo gains. Its larger flange improves joint stiffness to help reject bending moments from belt or pinion overhang.
Which drives and interfaces typically pair with MKD112C-058-KP0-BN, and what encoder-interface requirements exist?
The MKD motors are used with DDS/DKS/DKC/HDS/HDD drives, its resolver electronics supply position plus motor data memory to simplify commissioning. It supports drives with resolver/absolute transfer and the correct DC-bus for the 058 winding.
How should motion profiles exploit the 38 Nm standstill continuous torque on MKD112C-058-KP0-BN without exceeding thermal or current limits?
The shape S-curve profiles of peak current windows follws drive limits by using velocity feed-forward and jerk constraints. It monitors I²t and its housing temperature models avoid prolonged stall beyond continuous torque.
What does connector orientation code (e.g., “BN”) mean for MKD112C-058-KP0-BN and how does it impact EMC and routing?
The orientation of side B affects cable bend-radius planning, shielding continuity and strain relief in dense cabinets. It maintains short and segregates motor/encoder runs.
How does the resolver with integrated multi-turn absolute measurement (>4096 revolutions) on MKD112C-058-KP0-BN improve loop stiffness and disturbance rejection versus incremental encoders?
It eliminates homing, supplies absolute multi-turn position on power-up and preserves deterministic phasing for current control. Its integrated electronics present high-resolution position to the drive to improve velocity/position loop bandwidth under load transients.
