MDD025C-N-100-N2G-040FC1
The MDD025C-N-100-N2G-040FC1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a compact rotary actuator for digital drive controllers, it provides position and velocity control for small automation stages, pick-and-place heads, and indexing mechanisms. The motor uses frame size 025 with length code C, and the housing and rotor are supplied in the standard balance grade. It is intended for servo applications that require controlled acceleration and accurate stopping without the bulk of a larger motor frame. Its compact format suits light machine frames where responsive motion and stable alignment matter during frequent cycling.
This model reaches a nominal speed of 10000 rpm, allowing rapid cycle times in high-throughput cells. At standstill, it can maintain 0.90 Nm of continuous torque, while a blocking brake supplies 1.0 Nm of holding torque when the axis is powered down. The centering shoulder is machined to 40 mm, giving a precise reference surface for face mounting to gearheads or flanges. Power and feedback conductors exit on Side A of the housing, which can help keep cabling away from the driven load and simplify routing in enclosed axis modules. This cable exit position also leaves more usable space near the front mounting area for couplings and moving machine parts.
A pre-assembled connecting cable with a coupling unit links the motor to its controller and protects the resolver lines that carry resolver feedback for real-time position control. The single-ended rotor uses a plain shaft, so couplings or pulleys can be mounted without a key and balanced drivetrains can be kept simple. Because the unit is built without a shaft seal, it is best suited for installations where little coolant or oil spray reaches the output journal. The omitted rear shaft end saves space at the back of the motor, which is useful in compact carriages and closely spaced multi-axis assemblies. Resolver signaling also remains stable in industrial environments with electrical noise.
