Product Description:

The MDD025A-N-100-N2G-040PA1 is a compact synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is intended for use with digital drive controllers and supplies controlled rotary motion to positioning axes, pick-and-place heads, and other automation stages that require accurate speed regulation. Its compact housing helps the motor fit into tightly spaced machine frames, making it suitable for installations where available mounting space is limited but responsive motion is still required.

During operation, the motor provides a continuous standstill torque of 0.33 Nm, which suits small loads and light-duty holding tasks. Its maximum rated shaft speed reaches 10000 rpm, allowing fast indexing and short cycle times in compact automated equipment. A built-in blocking brake supplies 1.0 Nm of static torque to hold the axis when power is removed. The front flange has a centering recess of 40 mm for accurate concentric mounting, and the power and feedback leads exit on Side A, which helps keep cable routing orderly in narrow enclosures. Rotor balancing is standard, which helps reduce vibration during high-speed operation and supports smoother motion in repetitive cycles.

A single plug-in connector carries both power and sensor conductors, reducing the number of separate connection points on the housing. Position information is returned through resolver feedback, allowing the drive to monitor rotor movement for closed-loop control. The motor uses length code A, which keeps the frame compact for narrow axes and short installation spaces. A shaft seal protects the front bearing area from dust and coolant exposure, and the output shaft includes a keyway so couplings or pulleys can be locked in place securely. The shaft end is the standard version without a side B extension, which allows the motor to sit close to adjacent machine surfaces or gearbox faces.
