MKD112D-027-GP0-AN
MKD Synchronous Motors
The Bosch Rexroth Indramat MKD112D-027-GP0-AN from the MKD Synchronous Motors series delivers robust performance with a power rating of 16 kW and a torque rating of 75 Nm. It accelerates to a maximum speed of 6000 RPM while maintaining a compact weight of 45 kg for high-density installations. Rated for three-phase operation at 400V, this servo motor is built to withstand rigorous industrial demands. Its IP65 protection class ensures reliable operation in dusty or wet environments.
Mechanical integrity is reinforced by a shaft design with keyway and a shaft seal, ensuring secure torque transmission and contamination resistance. Without a holding brake, the rotor inertia is minimized, with a continuous torque at standstill of 48.0 Nm for precise positioning retention. The motor size 112 and motor length D adhere to global mounting standards, while a connection direction Side A simplifies panel integration. Designed for ambient conditions from 0 to +40°C and cooled via a standard cooling type, this motor maintains performance under varied thermal loads.
Feedback and control are driven by a high-resolution resolver feedback (RSF) encoder type and relative position detection, delivering smooth motion profiles. The winding code 027 is optimized for dynamic response, and the unit is classified as a servo motor product type. With no additional other designs or optional holding brake, the MKD112D-027-GP0-AN balances simplicity and high-precision functionality for demanding automation applications.

Frequently Asked Questions
How does the MKD112D-027-GP0-AN’s resolver (RSF) feedback influence commutation accuracy and vibration at high speeds?
The analog resolver delivers continuous sine/cosine signals for precise field-oriented control, which smooths torque production across the 0–6000 rpm range and minimizes acoustic/torque ripple. Its encoder unit includes data memory that streamlines commissioning with Rexroth digital drives.
Why is IP65 with a shaft seal and keyway significant for the MKD112D-027-GP0-AN in particulate or splash environments?
The sealing scheme limits ingress for protecting bearings, windings and feedback connectors during wash-spray or airborne dust exposure, while the keyed shaft provides repeatable torque transmission for couplings or pulleys. It enables use on packaging, printing and handling lines.
What mechanical implications follow from motor size 112, length D, and “connection direction Side A” on the MKD112D-027-GP0-AN?
The 112-frame (≈192 mm flange class) aligns with common IEC patterns and Side A connections simplify dress-pack routing in cabinets or machine-sideways exits. Its bearings are specified to allow direct overhung mounting of pinions or pulleys when radial loads are respected.
What considerations arise when operating MKD112D-027-GP0-AN continuously at 6000 rpm near rated torque?
Its sustained operation close to rated speed and torque increases copper and iron losses necessitates attention to ambient cooling airflow and load cycle factors to prevent demagnetization and insulation fatigue.
How does the MKD112D-027-GP0-AN connection direction “Side A” influence cabinet design and field cabling?
The side-A routing dictates cable entry orientation, reducing bending stresses in vertical enclosures. It improves EMC compliance and simplifies parallel motor wiring in multi-axis systems sharing common feedthrough plates.
