Frequently Asked Questions

What does insulation class F mean for MKD112D-027-GG0-AN with respect to thermal headroom and ambient 0–40 °C operation?

The class F insulation allows higher permissible winding temperature rise versus lower classes to preserve dielectric strength during continuous duty near nameplate torque. Its specified ambient range, thermal design margins support reliable torque delivery when cooling and cabling are implemented per guidelines.

How should a sealed plain shaft on MKD112D-027-GG0-AN guide coupling selection and ingress protection at the motor-machine interface?

The shaft sealing ring reduces lubricant egress and contaminant ingress but alignment and runout must stay within coupling tolerances to minimize seal wear. Its backlash-controlles elastic couplings and respect radial/axial load limits documented for MKD112 variants.

What mounting and alignment constraints follow from the 192 mm flange and Ø130 mm centering diameter for the MKD112 frame?

The centering spigot carries primary concentricity that datums the gearbox or machine plate to Ø130 mm to limit bearing preload. Its bolt pattern and flange size standardize interchange with other MKD112D variants for easing field replacements without re-machining.

Why does MKD112D-027-GG0-AN list 48.0 Nm continuous torque at standstill yet 47.4 Nm maximum torque and how should drives be tuned accordingly?

The MKD data segregate S1 stall torque and series peak/limit values, its controller current limits follow the lower of drive or motor tables. Its tune velocity and position loops are used to avoid sustained current saturation during low-speed indexing.

What are the commissioning implications of relative position detection on MKD112D-027-GG0-AN for safety-critical stop/restart routines?

Its position is incremental and homing or marker capture is required after each power cycle. It implement stateful restart logic prevent inadvertent motion on resolver index loss.

Internal Product Review

Bosch Rexroth Indramat develops the servo motor MKD112D-027-GG0-AN that comes with a built-in resolver-based feedback system. Its three-phase synchronous design is built with a 192 mm IEC-style flange and a sealed plain shaft. This motor has a rated speed of 6000 rpm and its torque delivery in standstill mode is 48 Nm that suits packaging, CNC machining, printing and material-handling cells, where resilient relative feedback within 0 – 40 °C is required.
