Product Description:
The MKD090B-058-KG2-KN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. Within industrial automation cells, it is installed on closed-loop drive axes. Its wound stator and feedback electronics convert drive controller commands into repeatable rotary motion for positioning, conveying, or tool manipulation tasks. This arrangement supports consistent speed and position control during indexing and transfer operations. The motor is suited to machinery that requires repeatable starts, stops, and directional changes.
The motor uses a 090 frame with a 140 mm square flange that mounts to machine plates. A 110 mm centering pilot keeps the motor concentric during installation, and the plain shaft includes a seal to help keep oil or coolant out of the bearing cavity. Continuous stall torque is 12.0 Nm when the winding temperature remains within the Class F insulation limit. Power and encoder conductors exit on Side B through a cast-aluminum connection box, which supports straightforward cable routing toward the cabinet. Housing joints and the connector gasket provide IP65 protection for use on production floors without extra covers. Winding code 058 and the B-length stator stack must match the settings used by the drive.
Rotor position is reported by resolver feedback, which uses an analog transformer pair and an integrated encoder interface. The signal provides Absolute (>4096 revs) multiturn position data, so homing is not required after power loss. System precision is rated at ±8 angular minutes, which suits mid-resolution indexing tables and material feeders. The motor can operate in ambient temperatures from 0–40 °C without derating when airflow around the housing is not obstructed. The drive controller must be compatible with the resolver wiring and insulation class, and the connection-box layout affects cable routing.
