Product Description:
The MKD090B-047-GG2-KN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. Intended for industrial automation, it converts controlled electrical input from a drive into precise rotary motion for positioning, indexing, and process control tasks on packaging, assembly, and material-handling equipment. As a closed-loop component, it works with Rexroth digital drives to maintain commanded speed and torque.
Its stall torque is 12.0 Nm, giving adequate low-speed force for holding loads without overheating. The mounting interface follows a 140 mm square flange, allowing direct installation with compatible gearheads and machine plates. For environmental protection, the housing carries an IP65 rating, so internal windings remain sealed against dust ingress and low-pressure water jets. Position feedback is delivered through resolver feedback (RSF), which outputs analog sine-cosine signals that the drive converts into digital angle data. Power and feedback cabling exit on Side B, which can simplify machine layouts that place the motor at the end of a moving axis. A connection box encloses the terminals and helps protect the conductors under vibration.
The dimensional envelope is tightened by the 110 mm centering diameter, while the plain shaft transmits torque without a keyway for couplings that rely on friction clamping. Relative position detection, combined with a system accuracy of ±8 angular minutes, supports use in medium-precision motion cells. There is a shaft seal, which helps keep lubricant from adjacent gear stages out of the stator cavity. Thermal behavior is supported by class F insulation and an operating window of 0–40 °C, making forced-air cabinet cooling unnecessary in many installations. The size code 090, length code B, and winding code 047 identify the active stack and copper content used for moderate current demand.
