MDD025C-N-100-N2G-040FF0
The MDD025C-N-100-N2G-040FF0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts regulated current from the drive into fast rotary motion for pick-and-place heads, compact spindles, and other high-cycle automation axes. Its compact housing supports installation where space is limited and where low inertia is important for short cycle times. The motor is suited to applications that need high speed with modest continuous torque in a small frame.
The motor delivers a continuous standstill torque of 0.90 Nm, which provides stable holding force during dwell periods. During operation, it can reach a nominal speed of 10,000 rpm, supporting fast acceleration in lightweight motion systems. A centering diameter of 40 mm helps align the flange accurately with the mating machine surface. Power and feedback conductors exit on the right side, which can simplify cable routing in compact gantries and other confined layouts. Electrical connection is made through a connecting cable with a coupling unit, allowing the motor to be disconnected without disturbing the entire cable run.
The model is supplied without a blocking brake, so any vertical or suspended load must be held by external locking hardware or by drive-generated torque when power is available. It uses a plain shaft, which is intended for friction-fit hubs and avoids the stress concentration associated with a keyway. The motor is also built without a shaft seal, so it should be installed in a clean area that is protected from fluid splash at the shaft opening. Position feedback is provided by resolver feedback, which supplies rotor angle information across the speed range and remains reliable under typical temperature variation in small motor frames. This feedback method supports stable speed control and accurate positioning in compact servo applications.
