Product Description:
The MKD090B-047-EG0-KN is a servo motor from the MKD Synchronous Motors series manufactured by Bosch Rexroth Indramat. It converts drive-controller current into precise rotary motion for packaging machines, gantry systems, transfer lines, and other industrial axes that require accurate speed and position control. The unit combines a size 090 frame, a B-length stator, and the 047 winding code to provide a balanced mix of inertia and voltage matching for mid-range motion applications. The motor is supplied without a holding brake, so any load that must remain fixed after power removal needs external holding support.
The motor uses a centering diameter of 110 mm and a square flange measuring 140 mm, which helps the housing seat accurately on mounting plates or gearbox faces. Power and feedback conductors exit on Side B, and the integrated connection box provides screw-terminal access for field wiring. At standstill, the motor delivers 12.0 Nm of continuous torque, allowing constant force on feed rolls, indexing tables, and similar driven elements without thermal overload. The flange geometry and cable exit arrangement also help keep installation compact while supporting consistent coupling alignment.
A housing rated IP65 resists dust ingress and low-pressure water jets, and a factory-installed shaft seal helps maintain that protection around the rotating element. The Plain shaft profile simplifies hub mounting and avoids the stress concentration associated with a keyway. Class F insulation supports the winding temperatures associated with high-duty operation, and the motor maintains its thermal limits in ambient temperatures of 0–40 °C. These characteristics make the motor suitable for enclosed equipment where direct shaft coupling and protection from common industrial contamination are important.
