Product Description:
The MKD090B-085-KG1-RN is a servo motor manufactured by Bosch Rexroth Indramat and supplied within the MKD Synchronous Motors series. Inside automated production cells, it delivers commanded torque and speed to linear tables, rotary indexers, and similar motion axes, forming the electromechanical link between the drive controller and the mechanical load. When paired with a compatible drive, it converts electrical commands into controlled rotary motion for repeatable positioning and stable speed regulation under changing machine loads. This operating role suits axes that must accelerate, stop, and hold alignment as product handling or indexing sequences change during each cycle.
The motor centers on a 110 mm pilot, allowing precise seating of the square flange that matches the 140 mm frame size. At zero speed, it can sustain a continuous torque of 12.0 Nm, so machinery can hold process loads without losing position. Rotor position is monitored by integrated resolver feedback, and the position memory exceeds 4096 revolutions for immediate position awareness at power-up. The enclosure is rated IP65, which helps protect the stator windings and bearings from airborne dust and directed water jets. Operation is permitted in ambient air from 0–40 °C, matching typical plant-floor conditions. Class F insulation tolerates winding temperatures up to 155 °C, and the B length code with the 090 frame code identifies the motor's stack height and diameter relationship for this model.
An electromechanical holding unit delivers 11 Nm of static brake torque so vertical or suspended loads remain fixed when drive power is removed. The plain shaft with a shaft seal limits lubricant escape and contaminant ingress at the output journal, while the internal feedback chain supports system precision of ±8 angular minutes for repeatable positioning. A rear power connector oriented to the right side simplifies cable routing in compact cabinets, and this layout suits packaging, material-handling, and light machining modules that require accurate motion through continuous duty cycles.
