The R911262938 (MKD090B-047-KG0-KN) servo motor is a brushless AC motor designed for automation and digital drive systems. It operates with a nominal speed of 3200 rpm and a maximum speed of 3500 rpm. In natural cooling mode, the motor achieves a maximum torque of 12 Nm, increasing to 15 Nm with surface cooling. It is compatible with AC 230 V (+10%) or AC 115 V (+10%) input. The motor is constructed with a plain shaft and shaft seal, resolver feedback with an integrated encoder offering absolute position detection greater than 4096 revolutions, and a system accuracy of ±8 angular minutes. A sealed terminal box facilitates electrical connections. The motor is built with a 140 mm frame, centering diameter of 110 mm, and satisfies IP65 protection class. It features insulation class F and can be mounted in any orientation. The holding brake is not included but may be added if required.

How does MKD090B-047-KG0-KN handle stationary load control?

It provides 12.0 Nm continuous torque at standstill, which holds commanded positions during dwells. This reserve limits drift and maintains fixture alignment.

What helps MKD090B-047-KG0-KN manage brief acceleration spikes?

Its 43 Nm peak torque accommodates short transients without reshaping profiles. This headroom supports clean starts and quick index moves.

What mounting feature stabilizes MKD090B-047-KG0-KN?

A 140 mm flange creates a broad, rigid interface. That footprint improves stability when coupling gearheads or pulleys.

How does the pilot support concentricity on MKD090B-047-KG0-KN?

The 110 mm centering diameter aligns mating hardware precisely. This geometry minimizes runout and vibration.

Why is insulation choice relevant on MKD090B-047-KG0-KN?

Insulation Class F withstands elevated winding temperatures. This rating supports continuous operation under sustained thermal load.
