Product Description:

The MKD090B-085-GP1-BN is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Within an automation cell, this brushless unit converts electrical drive commands into controlled rotary motion for positioning tasks and continuous-duty loads. Installed with a compatible drive controller, the motor supplies resolver-based feedback for closed-loop regulation and provides the mechanical interface required for industrial handling equipment, packaging machinery, or material processing stations.

At the flange, a diameter of 140 mm sets the mounting bolt circle, while a centering recess of 110 mm aligns the housing with associated gearboxes or frames. The continuous standstill torque reaches 12.0 Nm, allowing the axis to hold static loads without overheating. Protection to IP65 prevents dust ingress and low-pressure water jets, and insulation class F supports winding temperatures up to 155 °C. A resolver provides rotor position feedback, and the signals exit through an output connector. The rotor shaft includes a keyed section for positive torque transmission, and a shaft seal blocks lubricant migration. Motor size 090 with length code B determines the overall package length, and relative position detection suits servo loops that are re-referenced at startup. A spring-applied holding brake is integrated for power-off retention.

Field installation is simplified because all power, brake, and feedback plugs are oriented on Side B, keeping cable routing away from the driven machine face. During emergency stops, the brake delivers 11 Nm of retentive torque, which is suitable for moderate-inertia loads on vertical axes. For motion accuracy, the mechanical-electrical chain maintains a system precision of ±8 angular minutes, enabling repeatable indexing and coordinated multi-axis moves. The motor operates within a permissible ambient range of 0 to 40 °C, so it is suitable for standard industrial environments with normal ventilation.
