MKD090B-047-KP0-KN-SA001
The MKD090B-047-KP0-KN-SA001 is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It combines a 090 frame and B-length housing to supply medium rotational power for precision axes in automated packaging, handling, and assembly equipment. Driven by a compatible controller, the motor delivers repeatable torque while its integrated resolver supplies real-time rotor position so the drive can regulate speed and angle. This arrangement suits repetitive indexing and positioning tasks that require smooth starts, controlled stops, and consistent motion from cycle to cycle.
The mechanical interface uses a centering diameter of 110 mm and a square flange that measures 140 mm, allowing direct mounting to standard gearheads or machine plates. Thermal sizing yields a continuous standstill torque of 12.0 Nm, so the motor can hold or slowly move loads without exceeding its temperature limit. Position sensing relies on resolver feedback built into the housing, which avoids the need for a separate external encoder assembly. The output shaft uses a DIN keyway profile, and this shaft with keyway simplifies rigid coupling to pulleys or pinions. A shaft seal also helps block dust and oil splash at the drive end. Electrical behavior corresponds to winding code 047, which matches the voltage constant, resistance, and inductance used by MKD-compatible drives.
Cabling is routed on side B, where a sealed connection box houses the power, feedback, and ground terminals and keeps wiring away from rotating parts. The resolver provides multi-turn absolute feedback (>4096 revs), so homing routines are unnecessary after power loss. For applications that already have mechanical locking or vertical load support, the unit is supplied without a holding brake, which reduces inertial mass and maintenance points. The B motor length and 090 frame preserve the mounting pattern and drivetrain alignment used across this MKD size range.
