MKD112C-058-KP0-RN
MKD Synchronous Motors
The Bosch Rexroth Indramat MKD112C-058-KP0-RN from the MKD Synchronous Motors series is a precision-engineered Servo Motor designed for demanding automation applications. It operates across a Voltage Range of 110 – 480 V to deliver a Rated Speed of 3,000 rpm and a Rated Torque of 26.9 Nm, with the capability to reach a Maximum Torque of 87.9 Nm for short periods. At standstill, it maintains a robust Continuous Torque at Standstill of 38.0 Nm, ensuring stable holding performance under load. Its Winding Code 058 configuration optimizes thermal management, enabling continuous operation at rated torque without derating.
Constructed around an integrated Resolver feedback w/ integrated encoder, the MKD112C provides Absolute Position Detection over more than 4,096 revolutions for ultra-precise motion control. The rotor spins on a Shaft with keyway safeguarded by a durable Shaft Seal, and the housing meets IP65 Protection standards to resist dust and water ingress. Mechanical alignment is simplified by a Flange size of 192 mm and a Centering diameter of 130 mm, while the compact Motor Length C conserves installation space. Connection is handled via a standardized Power connector, and the design is offered Without holding brake and without Other Designs variants to streamline stocking and reduce complexity.
Weighing and balancing characteristics of the MKD112C combine rigidity with low inertia for fast acceleration and deceleration cycles in robotics, CNC machines, or packaging equipment. The integrated encoder–resolver feedback loop and rugged electrical architecture minimize tuning loops, shorten commissioning time, and enhance reliability under cyclic loads. Overall, the MKD112C-058-KP0-RN sets a new benchmark for efficiency, precision, and durability in high-performance servo applications.

Frequently Asked Questions
How do the IP65 housing and shaft-seal/keyed-shaft interface on MKD112C-058-KP0-RN affect contamination tolerance and torque transmission integrity?
The IP65 guidance addresses dust-tightness and water-jet exposure when correctly installed, while the shaft seal limits ingress along the output. Its keyed interface maintains positive torque transfer by aiding coaxial couplings in coolant-rich machine-tool envelopes.
For vertical or loaded axes, when is a holding brake advisable if MKD112C-058-KP0-RN already provides 38.0 Nm continuous standstill torque?
The continuous standstill torque resists drift under command, however safety-critical or de-energized holding often requires a brake. Its specifies brake as optional and warns additional safeguarding may be necessary for falling-load risk.
What mounting precision follows from the 192 mm flange and 130 mm centering diameter, and how does this influence gearbox or belt-drive alignment?
The centering pilot constrains runout and concentricity to allowing coaxial alignment with reducers or pulleys. Its 192 mm bolt circle provides stiffness against side loading to support repeatable kinematic alignment in multi-axis frames.
How do low rotor inertia and a 3,000 rpm nominal speed aid acceleration profiles on MKD112C-058-KP0-RN for robotics or pick-and-place?
The reduced polar moment lowers torque required to change speed for compressing accel/decel times and improving point-to-point throughput. Its resolver feedback, tight loop bandwidth is achievable by mitigating overshoot during aggressive S-curve profiles.
How do zero-pulse multiplicity and 4,096-rev absolute range on MKD112 influence gear ratio selection and feed constants?
The MKD071/090/112 encoders generate multiple zero pulses per revolution, so overly large ratios or tiny feed constants can alias reference marks. It maintains encoder granularity and reliable reference detection.
