Product Description:

The MDD025C-N-100-N2K-040FR0 is a small-frame AC synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit converts commanded current into proportional rotary motion for positioning, indexing, or light feed axes in industrial automation systems. Its compact 025 frame and C length code fit space-limited machinery while the standard housing and balancing allow direct mounting on precision assemblies.

At a continuous standstill torque of 0.90 Nm, the motor can hold moderate loads without overheating when stalled, supporting precise dwell phases in pick-and-place or inspection stations. Its rated speed of 10000 min⁻¹ enables fast indexing cycles as long as the drive delivers adequate frequency and voltage. Accurate mechanical alignment is assisted by the 40 mm centering diameter, which mates with standardized pilot fits on gearheads or machine frames. Power and feedback conductors exit through a Connector interface, simplifying swap-out in case of service, and these terminations are positioned on the Right side of the housing so cable routing can follow a common trunk along the machine base.

Position feedback is derived from an Integrated absolute encoder, which returns multi-turn position data to the controller without external sensors. Inside the stator the windings are wired for Resolver feedback, giving the drive analog sine-cosine signals for fine commutation even at high rotational speeds. The output shaft is a Plain shaft, permitting direct coupling with collets or miniature flywheels; there is no keyway to introduce imbalance in high-speed service. Because the motor is supplied without a shaft seal, installation in clean, dry enclosures is recommended when airborne oil or coolant could reach the bearing seat. A standard shaft end on side A and the absence of a blocking brake further minimize rotating inertia.
