Product Description:

The MKD090B-035-GP0-KN-SA001 is a servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. With size code 090 and length designation B, it suits medium-frame automation axes that need permanent-magnet torque under drive control. In industrial cells the unit translates inverter current into precise rotary motion, enabling coordinated positioning on packaging, handling, and metal-working equipment.

The motor can supply a continuous standstill torque of 12.0 Nm, delivering stable holding force without thermal overload when the shaft is locked. Installation follows the IEC square mounting interface because the flange is 140 mm across, and axial centering is maintained by a 110 mm pilot diameter for concentric alignment with gearboxes or frames. Feedback is generated by a Resolver feedback (RSF) transducer, giving analogue sine-cosine signals that remain immune to high temperatures and electrical noise. Power and signal exit on Side B, which places the terminal hardware opposite the driven machine and simplifies cable routing in compact cabinets. Within the MKD mechanical coding the stator uses winding code 035 to match inductance and back-EMF to standard drives.

These electromagnetic and geometric attributes integrate with installation features that complete the mechanical envelope. Field wiring enters through a connection box, allowing shield termination and strain relief on the housing itself. Because the rotor is equipped with a shaft with keyway, torque transmission to pulleys or couplings can be achieved without custom hubs, and a factory-installed shaft seal blocks lubricant ingress from adjoining gear stages. The unit is supplied without a holding brake, so static position retention must be provided by the drive or an external clamp when power is removed. Relative position detection, combined with the resolver’s electrical angle, satisfies indexing axes that are homed at start-up.
