Product Description:

The MKD090B-047-KP2-KS is a servo motor manufactured by Bosch Rexroth Indramat and sold within the MKD Synchronous Motors series. Intended for use with Indramat digital drive controllers, it serves as the rotating actuator in automated production lines, gantries, and packaging machines. By supplying controlled torque and velocity on demand, the unit links electronic motion commands to mechanical movement and supports synchronized positioning across multiple machine axes. This arrangement allows the motor to respond to changing speed and torque commands in closed-loop systems where accurate motion is required. The stator uses winding code 047, which matches the electrical characteristics expected by compatible power modules in the same platform.

It delivers a continuous standstill torque of 12.0 Nm, which provides a reference for static load holding without external brakes. The centering pilot of 110 mm ensures concentric seating against the machine frame, and the square flange spans 140 mm so standard bolt circles can be used without adapters. The mounting geometry helps maintain shaft alignment when the motor is coupled to gearboxes, pulleys, or direct-drive assemblies. A sealed housing with a rating of IP65 helps keep internal components isolated from dust and low-pressure water jets near coolants or cutting fluids. For velocity and phase feedback, the motor uses resolver feedback, allowing the connected controller to track rotor position during acceleration and deceleration.

Integrated electronics provide multi-turn absolute position information for more than 4096 revolutions, so the drive can retain position data across multiple shaft turns. The drive system uses a mechanical tolerance window of ±8 angular minutes for repeatable alignment between electrical zero and the shaft key. Power is transferred through a shaft with keyway, and a shaft seal helps limit lubricant migration. All electrical terminations are placed in a connection box on Side B, which keeps the wiring away from the driven load and can simplify cable routing. Insulation Class F supports winding temperatures up to 155 °C, and the assembly operates in ambient temperatures from 0 to 40 °C without derating.
