Product Description:
The MKD090B-047-KG1-KN is a servo motor from Bosch Rexroth Indramat that belongs to the MKD Synchronous Motors series. As a servo unit, it provides closed-loop rotary positioning for automated machinery and indexing axes in production cells. The motor uses a 090 frame with B length, and its plain shaft couples directly to gearboxes or driven loads. Integrated resolver feedback, together with absolute position detection beyond 4,096 revolutions, supports precise commutation and lets the connected drive track position after multiple shaft turns. This arrangement is suited to axes that must restart without a separate external encoder assembly.
The stator winding code 047 supports a continuous torque at standstill of 12.0 Nm, allowing the motor to hold a load at rated current without overheating. Radial location inside a machine frame is aided by a centering diameter of 110 mm, while the square mounting interface uses a 140 mm flange for alignment with compatible machine faces and adapter plates. Electrical angle information is returned as noise-immune analog signals to the drive controller, which helps stable operation where switching devices and motor leads are nearby. This output format is commonly used by servo drives that process sine and cosine signals for commutation and speed estimation. The mounting geometry and torque capability make the motor suitable for medium-inertia axes that need accurate positioning and repeatable holding performance.
A factory-installed holding brake applies 11 Nm of static torque, preventing back-driving when power is removed on vertical or suspended axes. Power and feedback leads exit on Side B, and terminations are completed inside a sealed connection box that helps keep conductors organized and strain relieved. There is a shaft seal so lubricants from adjacent gear stages do not enter the housing, and the plain shaft geometry simplifies coupling to clamped collars or other direct-drive hubs. With the brake, protected cable entry, and sealed shaft area, the motor fits enclosed machinery that requires secure standstill holding and clean internal routing.
