Product Description:

The MDD025B-N-100-N2K-040GF0 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies rapid speed regulation for compact axes found in packaging, pick-and-place, and small transfer stations. Size code 025, length code B, and a standard housing keep the overall envelope small, while standard rotor balancing limits vibration during continuous duty. The shaft end is supplied in a single-ended format, leaving side B free of an output shaft.

At standstill the motor delivers a continuous torque of 0.60 Nm, which is the sustained load it can hold without overheating. Its rated mechanical speed reaches 10000 rpm, allowing direct coupling to high-speed spindles or light-inertia loads. A centering diameter of 40 mm positions the flange concentrically in tight machine frames, and the power and feedback leads exit on the user’s right side, simplifying routing inside narrow enclosures. Electrical connection is made through a connecting cable with coupling unit, so field replacement does not require opening the motor case. The plain shaft transmits torque through clamping hubs without added axial features.

Position data are supplied by an integrated absolute encoder working in tandem with resolver feedback. This arrangement supports absolute position recovery at power-up and analog commutation for fast control loops. The unit is delivered without a blocking brake, which reduces mass and inertia when the machine already uses external holding devices. For environmental protection, the output end is fitted with a shaft seal, limiting the ingress of splash water or fine dust into the bearing cavity. When the axis is stopped, holding torque must come from the drive or from external machine hardware.
