Product Description:

The MKD090B-035-GG1-KS is a servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. This AC unit converts electrical energy into controlled rotary motion for positioning and velocity tasks in industrial automation. It uses motor size 090 with length code B and winding code 035, and it has a plain shaft with a shaft seal. Class F windings and the integrated holding brake make the motor suitable for precision axes that must maintain position when supply power is removed.

The motor provides a continuous standstill torque of 12.0 Nm, allowing it to support stationary load demand without excessive heat buildup. System accuracy is supported by a positioning precision of ±8 angular minutes, which helps the drive maintain repeatable alignment during indexing and short move cycles. The housing is sealed to IP65, keeping dust and low-pressure water spray away from internal components. Its mechanical interface uses a centering diameter of 110 mm and a square flange measuring 140 mm across. This arrangement supports direct mounting to machine frames or gear units and helps maintain consistent shaft alignment.

An electromagnetic holding brake provides 11 Nm of static torque for stopping and holding the axis during power loss. Rotor position is detected through Resolver feedback, which works with relative position evaluation in the connected drive controller. The motor operates in ambient temperatures from 0–40 °C, matching common industrial enclosures and machine interiors. Power and signal conductors exit on Side B through a sealed connection box, which can simplify cable routing where multiple axes share limited machine space. The shaft seal helps limit lubricant migration, and the closed connection area protects electrical terminations from contamination.
