MDD093A-N-030-N2K-110PB1
MDD Synchronous Motors
The MDD093A-N-030-N2K-110PB1, Bosch Rexroth Indramat, MDD Synchronous Motors represents a high-performance AC servo motor designed for demanding industrial automation tasks. This Product Type motor for digital drive controllers combines precision control with robust mechanical design to meet the needs of modern machine applications. The motor’s Motor Size 093 frame and Motor Length Code A deliver a balanced package optimized for space-constrained installations. With an integrated absolute Encoder, it provides accurate position feedback and seamless communication with Rexroth drive platforms.
Incorporating Standard Balancing and an optional With blocking brake mechanism, this servo motor ensures smooth operation and secure holding under load. The Holding Brake Torque of 11 Nm maintains shaft position during power loss or emergency stops, while the Theoretical Maximum Torque of 28.6 Nm supports dynamic acceleration and deceleration. Rated for a continuous Nominal Speed of 3000 min⁻¹ and capable of handling a Peak Current of 79.9 A, it achieves a Torque Constant At 20 °C of 0.52 Nm/A. The motor’s Centering Diameter of 110 mm and Standard (without side B shaft end) Shaft End are complemented by a With shaft seal design that resists contaminants in industrial environments. Its Side B Connection Direction simplifies cabling in tight chassis layouts, and the robust Housing protects internal components without compromising heat dissipation.
Engineers benefit from the motor’s low Rotor Moment Of Inertia of 22 x 10⁻⁴ kg•m², which enhances responsiveness in high-precision positioning tasks. At a Mass of 13.0 kg, the unit balances inertia requirements with ease of handling during installation. The MDD093A-N-030-N2K-110PB1 integrates seamlessly with Rexroth digital drive systems, delivering reliable performance and streamlined commissioning for robotics, packaging, and CNC machinery applications.
