MDD025A-N-100-N2K-040PF1
The MDD025A-N-100-N2K-040PF1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it provides rotational power and position feedback to compact automation axes in packaging, handling, and small assembly stations. The model uses a slim size 025 frame with standard housing and standard balancing, and its length code A keeps overall mass low for high-speed duties. Its compact dimensions suit small machine modules where fast acceleration, low inertia, and precise feedback are needed for short cycle times.
During continuous stall operation, the rotor can deliver 0.33 Nm of torque, enough to hold or creep lightweight loads without overheating. When velocity commands rise, the motor can accelerate to a rated speed of 10000 rpm, which suits high-speed indexing tasks. An integrated blocking brake supplies 1.0 Nm of static holding torque to secure vertical axes when power is removed. Position information is generated by an integrated absolute encoder, allowing the controller to read an unambiguous shaft angle immediately after startup. Power and feedback conductors leave the stator on the right side, which can simplify cable routing where multiple motors are lined up on a common rail. This combination supports motion tasks that require quick starts, controlled stops, and repeatable positioning over frequent duty cycles.
The centering pilot is machined to 40 mm so the flange can align precisely with gearbox or machine frames. Drive force is transmitted through a shaft with a keyway, and there is no shaft on side B. An internal resolver feedback channel maintains commutation if high-resolution position data from the encoder is lost. Electrical hookup uses a connecting cable with a coupling unit, and the shaft seal helps protect the bearings from dust and cutting fluids. The sealed shaft area supports use near dust or light fluid exposure where bearing protection is important for reliable operation.
