Product Description:

The MKD090B-035-KG1-KS is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It combines a size-090 stator with a B-length housing and uses winding code 035 to match drive controllers in medium-power axes. Intended for closed-loop motion, the motor uses an integrated resolver system to report rotor position to the control system. The windings use insulation class F, which supports the thermal endurance expected in continuous industrial automation. This configuration is suited to controlled rotary axes that require repeatable motion in handling, positioning, and general machine applications.

The motor delivers a continuous standstill torque of 12.0 Nm, providing steady force when the axis is stopped or moving slowly. Feedback is handled by resolver feedback with an integrated encoder, which provides analog sinusoidal signals with good immunity to electrical noise. Mechanical output is transferred through a plain shaft with a shaft seal, helping protect the internal bearings from contaminants during operation. A 140 mm flange supports mounting to standard gearbox or load interfaces, and the power and signal connections exit on Side B through a sealed connection box. The housing has an IP65 rating, which helps protect the motor against dust and water jets in industrial environments. The Side B cable exit can also simplify routing where the motor is installed close to guards, couplings, or machine frames.

A holding brake rated at 11 Nm stops motion when power is removed and can hold vertical loads without external clamps. Positioning accuracy is maintained to within ±8 angular minutes, and the feedback system tracks rotation over 4,096 turns to maintain absolute position data. The motor is intended for ambient temperatures from 0 to 40 °C, which fits common indoor industrial operating conditions. A 110 mm centering diameter helps the motor seat correctly in the mating machine frame and supports accurate mechanical alignment during installation.
