MDD025A-N-100-N2K-040GA0
Bosch Rexroth Indramat supplies the MDD025A-N-100-N2K-040GA0 in its MDD Synchronous Motors series. Classified as a motor for digital drive controllers, this compact synchronous unit is intended for automation axes that require fast indexing, smooth speed regulation, and direct coupling to precision gear stages. Its electrical design supports the high switching frequencies used by modern inverters, while the compact mechanical envelope suits miniature machines where low weight and inertia help maintain short cycle times. This format is well suited to tightly packed assemblies where small moving masses improve dynamic response and repeatability. The integrated feedback package also reduces external hardware around the axis.
The motor delivers a continuous standstill torque of 0.33 Nm, allowing it to hold light loads without overheating when the shaft is locked. During operation, it reaches a nominal speed of 10,000 rpm, which supports rapid point-to-point motion in compact pick-and-place frames. The flange uses a centering pilot of 40 mm to align the stator precisely with the mounting face. All electrical and feedback conductors exit on side A, and position data are supplied through integrated motor feedback, which eliminates the need for a separate external device. Because the unit is supplied without a blocking brake, load holding must be handled by the drive or by external mechanics.
The feedback signal sent to the controller is resolver feedback, which provides noise-resistant analog signals for high-speed interpolation. A plain shaft with a shaft seal helps block airborne contaminants and supports close-fit connection to miniature couplings. The motor size code 025 places it in the smallest frame of the series, and the standard housing uses a single-ended shaft layout suited to compact multi-axis assemblies with limited mounting space.
