MDD025B-N-100-N2G-040FF0
The MDD025B-N-100-N2G-040FF0 synchronous servo motor is produced by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts modulated current into rotational motion for compact axes in industrial automation, including pick-and-place heads and miniature gantry stages. The device uses the 025 frame in a standard housing, and its balancing is set to a standard grade to keep residual vibration low at elevated speed. This layout is well suited to small servo axes where low moving mass, quick response, and limited installation space are important.
The motor develops a continuous standstill torque of 0.60 Nm, which is suitable for holding light loads without external gearing. A nominal speed of 10,000 rpm pairs that torque with rapid indexing and high surface velocity. Precise mounting is supported by a 40 mm centering diameter, and wiring exits on the right side of the stator. Power and feedback are routed through a connecting cable with a coupling unit, which helps keep cable routing compact on modular machines. Position data is returned through resolver feedback, giving the drive an analog angle signal that remains stable at elevated temperatures. The motor uses length code B for the active stack, which suits dynamic micro-axis duty cycles.
It is delivered without a blocking brake, so any static holding duty must be supplied by the drive or by an external brake module. The rotor uses a plain shaft with no keyway, and the side-B extension is omitted for this shaft-end arrangement. Because the shaft has no keyway, torque is typically transferred through a clamping hub or a similar friction-based coupling. To minimize friction, the motor is also supplied without a shaft seal. If liquids are present, a separate enclosure seal is required. In dry, enclosed equipment, this arrangement reduces drag at the shaft and avoids contact from an added lip seal.
