Product Description:

The MDD025C-N-100-N2K-040GB1 is a small-frame synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it translates commanded current into precise rotary motion for positioning axes or light spindles in automated machinery. By combining feedback, braking, and sealing features inside a compact envelope, the unit supports high-speed pick-and-place, packaging, and electronics assembly lines that demand reliable cycle accuracy and minimal downtime.

The rotor is balanced to the standard class, and the centering flange measures 40 mm, enabling accurate coaxial alignment with gearboxes or couplings. A nominal speed of 10000 min⁻¹ supports rapid indexing, while the continuous stall torque of 0.90 Nm lets the axis hold load during dwell periods. For emergency stops, the built-in blocking brake applies 1.0 Nm of static torque. Motion feedback is delivered by an integrated absolute encoder that works with resolver electronics for fine-resolution velocity and position data. Power and signal terminations exit on Side B of the housing, keeping cables clear of moving assemblies and simplifying routing in confined enclosures.

The electrical interface is a sealed Connector that permits quick removal without rewiring. An internal lip maintains lubrication and blocks contaminants because the shaft is fitted with a shaft seal. The output is a plain shaft supplied without a rear-side extension, so couplings or pulleys seat directly on the main journal. Frame size 025 fixes the external diameter group, and motor length code C sets the active stack depth for higher peak torque without altering the mounting circle. Standard housing construction and balancing ease interchange across the series, while resolver feedback remains available for controllers that require analog sine-cosine signals.
