MDD025B-N-100-N2K-040FB0
The MDD025B-N-100-N2K-040FB0 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies controlled torque and speed to compact axes in automated assembly stations, pick-and-place units, and semiconductor handling equipment. This type of motor is suited to applications that need fast response, accurate positioning, and stable low-inertia operation across repeated cycles. Its mechanical outline follows the standard housing dimensions used in the series, supporting straightforward installation in compatible machine layouts. The motor is supplied without a blocking brake, so holding torque at standstill must be provided by the connected drive when power is removed.
At the electrical level, the motor reaches a nominal speed of 10000 rpm, enabling rapid tool or gripper rotation when load inertia is low. Continuous torque available at standstill is 0.60 Nm, allowing the drive to apply controlled force for fine positioning before motion starts. For mechanical centering, the flange provides a 40 mm pilot diameter, which helps align the shaft axis with the machine frame. Power and feedback conductors exit on Side B, and a keyed connector supports a secure plug-in cable connection. Standard dynamic balancing helps keep vibration within permissible limits during full-speed operation.
Position information is generated by resolver feedback together with an integrated absolute encoder, so the controller receives coarse and fine angle data without external sensors. This feedback combination supports stable commutation and accurate position tracking across the operating range. Motion is delivered through a plain shaft, and motor size code 025 identifies the compact frame used for small servo axes. Because there is no shaft seal, the installation site must remain free of coolant or oil spray. The motor uses length code B, which provides a moderate stack length, and the housing has no second shaft end on side B, leaving space for the rear connector arrangement.
