Product Description:

The MDD025C-N-100-N2G-040PR1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for direct coupling to digital drive controllers, the unit delivers motion control for light industrial axes where rapid positioning accuracy and high spindle speed are required.

At its nominal speed of 10000 min⁻¹, the rotor can follow high-frequency command changes without loss of synchronization, making it suitable for pick-and-place heads and small tooling spindles. A continuous standstill torque of 0.90 Nm defines the force available for holding loads when the shaft is energized but not rotating, while the integrated brake can arrest motion momentarily with 1.0 Nm of static torque during power-off events. The flange’s centering recess measures 40 mm in diameter, providing a reference surface that simplifies coaxial alignment with gearboxes or machine frames. Position feedback is supplied through resolver feedback, allowing the drive to close the control loop with analog accuracy even in electrically noisy cabinets. Power and feedback leads exit on the right side of the housing to match cabinet layouts that favor right-hand routing, and the motor size 025 frame keeps the footprint minimal.

Mechanical details finalize the installation envelope. The rotor is balanced to Standard quality so vibration remains within tolerances at full speed. A keyway shaft transmits torque without slippage, and the single-ended shaft design leaves side B closed for compact mounting. The power socket is a Connector type, so cabling can be detached quickly during service. Motion retention is provided by a built-in blocking brake, and protection against lubricant ingress is added by a shaft seal. A Standard cast-aluminum housing encloses the C-length stator stack, and the resolver, connector orientation, and shaft seal all integrate without exceeding the 100 mm overall body length implied by the motor length code C.
