MKD090B-085-GG1-AN

The Bosch Rexroth Indramat MKD090B-085-GG1-AN servo motor from the MKD Synchronous Motors series is engineered to deliver reliable performance in demanding industrial automation applications. This permanent-magnet servo motor features a robust plain shaft design combined with integrated resolver feedback (RSF) for precise position detection. Housed in a durable enclosure with an included shaft seal, the MKD090B-085-GG1-AN provides resilient protection against contaminants while maintaining high mechanical stability. The compact form factor, identified by motor length code B, supports flexible mounting options and simplifies installation across diverse machine layouts. It is optimized for continuous operation at standstill, boasting a continuous torque at standstill of 12.0 Nm and the ability to sustain rapid speed changes without maintenance.

Detailed technical specifications of the MKD090B-085-GG1-AN outline its capacity to support high dynamic loads and control requirements. The motor uses a windings code 085 and an 8-pole configuration to achieve a maximum speed of 6000 RPM under peak drive conditions. It draws a peak current of 33.4 A during transient loads, while the standard power interface is provided via a connector at top for streamlined cabling. Mechanical connection to the driven system is facilitated through a flange size of 140 mm and a connection direction on Side A, ensuring compatibility with standard mounting hardware. With position detection set to Relative and servo control executed by the resolver feedback, this unit guarantees repeatable accuracy and tight closed-loop response.

Operational features focus on safe handling and high availability in continuous-duty scenarios. The MKD090B-085-GG1-AN is equipped with holding brake, delivering a holding brake torque of 11 Nm to secure the motor shaft during power-off or emergency stops. Brake performance includes a clamping delay of 13 ms and a release delay of 30 ms, supporting rapid cycle times while minimizing downtime. A sealed bearing and plain shaft arrangement reduce maintenance requirements and prevent ingress of contaminants. The motor’s robust design and integrated feedback ensure stable torque delivery and dynamic response, making it suitable for high-speed indexing, precision pick-and-place, and tension control applications.

System integration is simplified through Bosch Rexroth’s standardized interfaces and the proven reliability of the MKD Series. Engineers can leverage the MKD090B-085-GG1-AN in combination with Rexroth servo drives and motion controllers to implement coordinated multi-axis systems, robotics, and automated assembly lines. The unit’s product type: Servo Motor designation and comprehensive spec sheet facilitate fast selection, procurement, and commissioning in OEM and retrofit projects. Target applications include packaging machinery, CNC equipment, and material handling installations where precise position control, repeatability, and low maintenance overhead are essential.
