MDD093C-N-020-N2M-130PB1

The Bosch Rexroth Indramat MDD093C-N-020-N2M-130PB1 is a high-performance digital AC servo motor in the renowned MDD Synchronous Motors series, engineered for precision motion control in demanding industrial environments. This compact motor combines permanent-magnet rotor design with advanced digital commutation, delivering smooth torque and rapid response across its operating range. Featuring a nominal speed of 2000 min⁻¹ and an integrated blocking brake, the unit ensures reliable holding capability even in vertical or suspended axis applications. With an overall motor length code of C and a standardized housing footprint, the MDD093C-N model provides an optimal balance of power density and installation flexibility.

The motor’s mechanical and electrical interface is defined by a motor size of 093 with a precision machined centering diameter of 130 mm for direct coupling to machine elements. The integrated multiturn absolute encoder provides real-time position feedback with no battery backup required, while the digital servo feedback (DSF) system supports advanced commutation and speed regulation. The shaft is configured with a keyway per DIN 6885 sh.1, Edition 8-68 and sealed by a shaft seal, ensuring protection against contaminants. Electrical connection is handled via a side-mounted connector on Connection Direction: Side B, simplifying cabling in compact drive cabinets. The standardized housing and balancing rating enable interchangeability with other MDD variants.

Operational performance is governed by precision rotor position and speed control algorithms that leverage the absolute encoder data to maintain stable torque output under dynamic load conditions. The built-in blocking brake exerts 11 Nm of holding torque, securing the load instantly upon power loss or emergency stop. Standard balancing reduces vibration and noise at high rotational speeds, while the permanent-magnet design ensures consistent flux linkage and low inertia for rapid acceleration and deceleration. The motor for digital drive controllers is optimized for seamless integration with Rexroth Indramat controllers, enabling real-time tuning, auto-gain adjustment, and predictive maintenance diagnostics.

System integration is streamlined through compliance with established drive communication protocols and mechanical interfaces used across Bosch Rexroth Indramat platforms. The MDD093C-N series motor’s compact dimensions, precise encoder feedback, and robust braking function make it ideal for applications such as CNC machining centers, robotic articulation modules, packaging lines, and automated assembly systems. Engineers will appreciate the motor’s combination of high dynamic performance and straightforward mounting provisions when designing multi-axis motion systems requiring tight synchronization and high repeatability.
