Internal Product Review
The MKD090B-047-EG1-KN is a servo motor with IP65 protection that looks well suited for demanding automation service. An integrated holding brake with 11 Nm brake torque adds valuable control for vertical axes and secure stopping. Strong standstill output remains a key advantage at 12.0 Nm continuous torque.

Product Description:
The MKD090B-047-EG1-KN is a servo motor manufactured by Bosch Rexroth Indramat for the MKD Synchronous Motors series. It serves as the electromechanical element in an integrated drive system, converting controlled current from a drive controller into repeatable rotary motion for positioning tasks. This makes the motor suitable for tooling axes, conveyor sections, and indexing tables that require accurate movement during repeated machine cycles. Its design supports controlled acceleration, steady operation at low speed, and reliable positioning in automated equipment.
The motor provides a continuous standstill torque of 12.0 Nm, allowing it to hold static loads at zero speed without thermal overload under normal operating conditions. A square flange of 140 mm mounts directly to common machine faces, and a centering diameter of 110 mm helps maintain accurate shaft alignment during installation. The housing is sealed to IP65, which helps block dust and low-pressure water spray in washdown or material-processing areas. Windings built to insulation class F tolerate internal temperatures up to 155 °C. Power and feedback connections are routed on side B through a fixed connection box, and the plain shaft uses a shaft seal to help limit lubricant loss and contaminant entry at the output end.
An integrated holding brake delivers 11 Nm of torque, so the rotor can be mechanically locked during power-off conditions or emergency stops. The permissible ambient operating range is 0–40 °C, which fits typical factory environments without added climate control. Frame size 090 indicates the motor’s stator diameter, while the B length code provides a balanced relation between inertia and torque for this housing size. The winding code 047 identifies the electrical configuration used with compatible Indramat drive modules for proper voltage and current matching.
