Product Description:

The MDD025B-N-100-N2G-040ML1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated current into controlled shaft rotation for small positioning axes and spindle drives in automated equipment. The compact housing supports installation where machine space is limited and where short response times are important for repeatable motion. Its standard balancing helps maintain smooth running during rapid starts, stops, and direction changes.

Mechanical interface dimensions start with a centering shoulder of 40 mm that aligns the motor on the mounting surface. Power and feedback cabling exit on the left side through a sealed connector, which can simplify routing when the driven load is positioned on the opposite side. The motor develops a continuous standstill torque of 0.60 Nm, and it reaches a nominal operating speed of 10000 rpm, making it suitable for light loads that require fast rotational movement. The 025 frame size corresponds to the small motor diameter used in this family, and the housing uses natural convection so no auxiliary fan is required.

The unit is equipped with a blocking brake that produces 1.0 Nm of holding torque, helping secure vertical or creeping axes when drive power is removed. Overall motor length follows code B, which keeps the assembly short enough for installations with limited axial space behind the mounting face. Position feedback is provided by resolver feedback, which supplies noise-resistant angle signals to the controller for stable commutation and speed regulation. Torque is transmitted through a keyway shaft, and the motor is built without a shaft seal or a side-B shaft end for use in clean, dry enclosure conditions. This arrangement keeps the output interface straightforward for direct coupling to common machine elements.
