Product Description:

The MDD025C-N-100-N2G-040GC0 is a compact synchronous motor manufactured by Bosch Rexroth Indramat for inclusion in the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies controlled rotary motion to small pick-and-place axes, indexing tables, and electronic cam followers. The design uses motor size 025 with length code C, and both the housing and the rotor balancing follow the standard options provided by the series. These attributes let the machine builder integrate the unit into high-speed servo loops without additional mechanical adaptation.

At standstill the motor produces a continuous torque of 0.90 Nm, providing stable holding force for precision positioning tasks. During operation it can reach a nominal rotor speed of 10000 min⁻¹, so drive controllers can exploit wide velocity ranges without gear reduction. Position and velocity data are returned via resolver feedback, allowing the controller to close current and speed loops with fine resolution. All power and feedback conductors exit on Side A, and the factory-installed connecting cable with coupling unit minimizes wiring time inside crowded enclosures.

Mechanical integration is simplified by a centering shoulder measuring 40 mm in diameter that aligns the flange to the machine frame. The motor transmits torque through a plain shaft; a with shaft seal arrangement prevents lubricant migration into the stator cavity and blocks dust ingress to IP-rated levels. Because the shaft end is supplied in the standard single-ended form, there is no side-B extension to interfere with adjacent hardware. The unit is delivered without a blocking brake, so applications that demand static holding torque must rely on external clamps or the drive’s electronic braking functions.
