MDD025A-N-100-N2G-040GE0
The MDD025A-N-100-N2G-040GE0 is a synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive output into controlled mechanical rotation for high-speed automation stages, pick-and-place heads, and compact spindle drives. Its compact frame supports installation in tight mechanical envelopes common in semiconductor handling and light assembly equipment. The motor is suited to axes that need quick response, consistent speed control, and repeatable motion in a small package.
At full excitation, the motor reaches a nominal speed of 10000 rpm, supporting short machine cycles and rapid repositioning. Continuous standstill torque is 0.33 Nm, allowing the axis to hold position without overheating during low-speed or stationary operation. Power and feedback leads exit on the left side, which can simplify cable routing where space around the motor is limited. A centering diameter of 40 mm assists precise mounting, and torque is transmitted through a plain shaft that accepts user-supplied couplings. A connecting cable with a coupling unit allows plug-in installation, while the side-A shaft end is standard and no extension is provided on side B.
Dynamic position feedback is delivered by resolver feedback, which supplies rotor position signals to the drive for closed-loop control across the speed range. The motor belongs to size 025 and uses the short A length code, helping reduce axial space and rotor mass in compact mechanisms. Internal balancing is set to the standard level to limit vibration during high-speed operation. Motion surfaces are protected by a shaft seal, which helps keep oil mist or coolant splashes away from the bearings. The motor is supplied without a blocking brake, so any holding function at standstill must be provided by drive torque or an external mechanical device.
