Product Description:

The MDD025C-N-100-N2K-040GE1 is a synchronous motor from Bosch Rexroth Indramat that belongs to the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts electrical commands into precise mechanical motion for high-speed automation axes where tight velocity and position regulation are required.

At its nominal speed of 10000 min⁻¹, the rotor can execute rapid indexing or light-spindle duties. During standstill it produces a continuous torque of 0.90 Nm, defining the load it can hold thermally. A built-in blocking brake supplies 1.0 Nm of holding force to secure the axis when power is removed. Accurate position data comes from the motor’s integrated absolute encoder, allowing instant reference on restart. Machine mounting is simplified by a centering shoulder that measures 40 mm in diameter, and power plus feedback conductors exit on the left side of the housing.

The motor body follows a standard balancing grade and resides in a standard enclosure that includes a shaft seal for fluid protection. Cabling is handled through a connecting cable with coupling unit, and internal windings are monitored via resolver feedback for sinusoidal position information under dynamic loads. Dimensional fit is set by size code 025 and length code C, helping designers align this frame with other MDD units. A plain shaft without a side-B extension supports direct coupling to pulleys or collets while keeping inertia low.
