Product Description:
The MKD090B-047-KG1-KS is a servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series and is intended for precision motion in automated machinery. It combines a 090 frame with the B length code to suit mid-range power requirements while limiting overall depth. A resolver feedback unit with an integrated encoder provides absolute position detection beyond 4,096 revolutions, allowing closed-loop control without external sensors on each axis. Because absolute position remains available across multiple turns, the motor can support repeated axis travel without depending on separate reference devices. This arrangement helps the drive maintain repeatable position and speed control in handling, assembly, and packaging equipment.
This motor delivers a continuous standstill torque of 12.0 Nm through a plain shaft with a shaft seal. The mechanical interface uses a 140 mm square flange and a centering diameter of 110 mm, so it mounts directly to standard gearboxes or machine plates. Electrical power and feedback conductors are routed on Side B through a connection box, which can simplify cable routing in compact installations. The housing is rated IP65, and the motor maintains positioning accuracy within ±8 angular minutes across its operating range. Winding code 047 identifies the electrical winding used with compatible drive controllers. The sealed shaft area also helps protect internal bearing components from dust and splashed liquids during routine operation.
An integrated braking module specified as with a holding brake supplies static holding capability for axes that must remain stable during power loss. The brake torque of 11 Nm works with insulation class F materials to tolerate winding temperatures up to 155 °C. Operation is permitted at ambient temperatures from 0–40 °C, so the motor can run in typical machine enclosures when adequate airflow is available. The brake supports load retention when the axis is stopped, while the servo controller continues to manage dynamic motion during normal operation. It is commonly used on pick-and-place gantries, tool changers, and indexing tables that require stable positioning during stops as well as accurate closed-loop movement.
