Frequently Asked Questions
What are the mechanical integration implications of the 192 mm square flange and 130 mm centering diameter on MKD112D-027-GG0-BN?
The 192 mm IEC-style flange with a 130 mm pilot simplifies concentric alignment to reducing coupling runout and bearing load. It eases drop-in mounting on heavy machine axes and packaging stations.
Why specify a plain shaft with sealing ring on MKD112D-027-GG0-BN for washdown-adjacent or dusty environments?
The plain shaft plus seal limits ingress along the shaft line for complementing the motor’s enclosure rating and extending service life of front bearings. It’s useful where airborne particulates or splash are present.
How does the RSF resolver in MKD112D-027-GG0-BN influence commutation quality and position observability under electrical noise?
Its analog resolver (RSF) delivers sine/cosine signals enabling robust relative position detection and stable field-oriented control, even with inverter switching noise and EMI. Its drive interpolation yields fine electrical angle resolution for smooth torque production across speed ranges.
How does the side-B power connector orientation on MKD112D-027-GG0-BN influence cabinet and cable routing in tight machines?
The side-B orientation allows rearward/side exit to avoid cable loops near moving guards for improving EMI separation from feedback lines. It also mirrors common Rexroth cabinet layouts for cleaner harnessing.
What thermal and environmental boundaries should be respected when deploying the MKD112D family on factory floors?
Its ambient 0–40 °C, storage −20–80 °C and installation ≤1000 m elevation, with insulation class F and IP65 enclosure constraints. It needs additional cooling as conditions approach these limits.

Internal Product Review
The Rexroth Indramat's MKD112D-027-GG0-BN synchronous servo motor pairs a plain shaft with sealing ring and uses RSF resolver for relative feedback. It possesses D-length frame and it provides 48 Nm at standstill. This motor comes with a 192-mm flange, Ø130-mm pilot, side-B connector and lacks any brake assembly. It is ideal for printing, machine tools and food packaging automation systems.
