Product Description:

The MKD090B-085-GG0-AN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. With its motor size 090 housing and B length code, the device supplies controllable rotary power to automated axes used in packaging, printing, and material-handling equipment. When paired with a compatible drive controller, it delivers closed-loop speed and position regulation that supports precise indexing, smooth velocity profiles, repeatable cycle timing, and steady motion during frequent start-stop operation under varying load conditions.

At standstill, the motor sustains 12.0 Nm of continuous torque, allowing fixtures or loads to remain clamped without overheating the windings. A centering pilot of 110 mm aligns the stator concentrically to adjoining mechanics, and a square flange of 140 mm sets the bolt pattern for rigid mounting. Rotor angle is reported through resolver feedback (RSF), which supplies sine-cosine signals for digital commutation and velocity control. All power and feedback conductors exit on Side A, which simplifies wiring when the cabinet is positioned on that side of the machine. The resolver also supports relative position detection, and the B-length stator provides additional copper mass for improved continuous power density.

Cabling attaches through an output connector that accepts standard hybrid plugs, while mechanical energy is delivered by a plain shaft that is free of keyways to reduce stress concentrations. The motor is supplied without a holding brake, so external braking or drive-torque locking is required when power is removed. A shaft seal is fitted to keep contaminants away from the front bearing and to retain lubricant under light washdown conditions. This arrangement suits servo axes that need reliable positioning, consistent reversals, stable operation across repeated machine cycles, and clean coupling to external transmission components.
