MDD025C-N-100-N2K-040GB0
The MDD025C-N-100-N2K-040GB0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use in digital drive controller systems, where it provides closed-loop rotary motion for light loads that must accelerate and decelerate quickly. Its compact size makes it suitable for tightly spaced automation equipment that still requires accurate speed and position control. The motor is well suited for small handling axes, indexing tasks, and other applications where responsive motion is more important than high continuous torque.
The motor delivers a continuous standstill torque of 0.90 Nm, which supports precise holding and low-speed indexing. It can reach a nominal speed of 10,000 rpm, and power and feedback conductors exit through a connector on side B to simplify cable routing in narrow cabinets. A centering recess of 40 mm helps align the flange on standard mounting surfaces, improving repeatable installation. Rotor position is reported through resolver feedback, which provides analog sine-cosine signals for real-time control and stable motor operation across a wide speed range.
The motor uses a plain shaft for direct coupling with collets or precision pulleys, and the shaft seal helps protect the internal bearings from dust and lubricant splash. An integrated absolute encoder provides position data after startup, while the motor is supplied without a blocking brake, so external holding torque is required for vertical loads or any application that must remain fixed with power removed. It uses standard balancing to limit vibration at high speed, which helps maintain smooth rotation during rapid moves. The housing is made of standard cast aluminum, and the motor has a single shaft end on the drive side to keep the rotating assembly compact.
