Product Description:

Bosch Rexroth Indramat manufactures the MDD025C-N-100-N2K-040FR1 within the MDD Synchronous Motors series. The unit is a compact permanent-magnet servo motor intended for digital drive controllers in automated machinery, where it converts controlled electrical power into precise high-speed rotation for tasks such as small-axis positioning and spindle duties.

The rotor is balanced to the standard class, and its centering flange measures 40 mm, enabling accurate concentric mounting in tight frames. Under continuous stall conditions the motor delivers 0.90 Nm of torque, while the winding design supports a nominal speed of 10000 min⁻¹ so high-throughput cycles can be reached. A blocking brake is integrated and supplies 1.0 Nm of static holding torque to secure the load when power is removed. Electrical and feedback leads exit to the right because the connection orientation is fixed on that side, and power is routed through a single Connector that mates with standard hybrid cables. The housing and overall mechanical construction follow the series’ standard pattern, giving consistent thermal behavior across the 025 size.

Rotor position data are returned via Resolver feedback, and multi-turn position is tracked by the built-in Integrated absolute encoder; together these devices allow the drive to close velocity and position loops without external sensors. The plain output shaft is a Plain shaft style and is supplied from the factory Without shaft seal, so the installation must be protected from coolant ingress. The shaft end is the standard form without a side-B extension, motor length code C defines the active stack, and the connection type’s right-hand exit helps keep cables clear of adjacent axes. A standard aluminum housing aids heat dissipation, and the 025 frame maintains uniform inertia across machines that share this motor size.
