Product Description:

The MKD090B-047-KP0-KN is a synchronous motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a rotary drive element, it converts electrical energy into controlled torque and speed for industrial automation axes such as packaging stations, material-handling gantries, and machine-tool spindles. Its mechanical dimensions fit the 090 frame class and the B length code, giving the motor a standardized footprint for compact machine layouts and multi-axis assemblies. This arrangement supports repeatable servo motion where stable speed and precise shaft positioning are required under changing load conditions.

The motor can deliver a continuous standstill torque of 12.0 Nm, allowing it to hold static loads without overheating when controlled by the drive. A centering diameter of 110 mm aligns the housing concentrically with the driven machine, which helps reduce runout at the coupling interface. All power and feedback leads exit on side B, so cable routing remains predictable in mirrored or tandem installations. Terminations are made inside a connection box that helps protect joints from vibration and contaminants. A 140 mm square flange matches common IEC mounting patterns and supports direct installation on compatible machine faces.

A resolver feedback sensor is integrated to provide analog sine and cosine signals for velocity and position evaluation. The motor also has absolute position capability of more than 4096 revolutions, so the axis can power up with stored position information and may not require a homing cycle. The shaft with keyway transfers torque positively into pulleys or couplings, and the shaft seal helps block dust and oil entry at the output end. Because the unit is supplied without a holding brake, an external clamp is required when vertical load retention is needed. The winding code 047 indicates the electrical resistance and inductance set used by compatible Rexroth drives, supporting thermal balance at rated load.
