MDD090A-N-030-N2M-130GB2

The Bosch Rexroth Indramat MDD090A-N-030-N2M-130GB2 is a high-performance member of the MDD Synchronous Motors series, engineered for precision motion control in digital servo systems. This Digital AC servo motor features a permanent-magnet rotor design and an integrated multiturn absolute encoder for commutation, rotor position, and speed control. With its robust construction by Bosch Rexroth Indramat, the MDD090A offers reliable operation under continuous industrial loads and precise responsiveness across a wide speed range. The motor is equipped with a plain shaft output, facilitating straightforward mechanical coupling and minimizing alignment complexity in machine designs. This part’s combination of advanced feedback technology and compact form factor makes it ideal for integration into modern, high-density automation equipment.

The MDD090A’s technical specifications define its capability envelope. It features a Centering Diameter of 130 mm and a Motor Length Code A housing with a standard balancing grade. The motor’s Motor Size 090 provides a balanced power-to-volume ratio, while the Continuous Torque at Standstill of 3.7 Nm ensures stable holding under load. Rated for a Nominal Speed of 3000 min⁻¹, the unit operates efficiently in tandem with Rexroth’s digital drive controllers. A blocking brake with Holding Brake Torque of 11.0 Nm delivers immediate fail-safe retention, and the integrated shaft seal protects internal components from contaminants.

Operational features emphasize precise, digital closed-loop control and seamless feedback integration. The motor’s Digital Servo Feedback (DSF) mechanism works in concert with the integrated multiturn absolute encoder to achieve sub-micron position resolution and automatic commutation. The plain shaft design reduces inertia mismatches, improving dynamic response, while the motor’s standard balancing minimizes vibration at high speeds. With a connection direction Side B and a robust connector interface, installation and maintenance are streamlined, reducing downtime in production environments. Built for consistent performance, the motor maintains torque output and feedback fidelity even during rapid acceleration or deceleration cycles.

This servo motor is optimized for seamless system integration with Bosch Rexroth Indramat digital drive controllers, supporting industry-standard communication protocols and real-time diagnostics. Its compact footprint and comprehensive feedback systems suit applications in CNC machine tools, robotics, packaging machinery, and semiconductor handling equipment. The robust design, coupled with precise digital control, makes the MDD090A particularly well suited for environments demanding high throughput, minimal maintenance, and maximum positional accuracy. Engineers will find the MDD Synchronous Motor a versatile solution for modern motion-control challenges.
