MDD025B-N-100-N2G-040GC1
The MDD025B-N-100-N2G-040GC1 is a compact AC synchronous motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it is intended for tightly regulated positioning or velocity loops in small-frame automation axes. It is well suited to compact servo applications such as feeders, pick-and-place units, and other motion tasks that require accurate speed and position control. Integration is simplified by a built-in blocking brake that secures the load at standstill, and the standard housing and balancing fit common mounting fixtures used in multi-axis machines. That combination supports stable operation in compact machine sections where controlled stopping is as important as responsive motion.
This model delivers a continuous standstill torque of 0.60 Nm, enabling light rotary loads to remain energized without thermal overload. When motion is commanded, the rotor can reach a nominal operating speed of 10,000 rpm, which suits fast indexing and other high-speed duties. The blocking brake provides 1.0 Nm of holding torque, allowing vertical or intermittent-duty axes to maintain position during power-off events. Rotor position is returned to the drive through resolver feedback, so phase information remains available during acceleration, deceleration, and rapid reversal. Mechanical output is transferred through a plain shaft, allowing the motor to be paired with friction-locking couplings without introducing keyway stress points.
Physical alignment is guided by a 40 mm centering diameter, and power and feedback conductors exit on Side A through a connecting cable with coupling unit, which helps keep routing orderly in shallow machine spaces. A sealed front end helps prevent lubricant escape and contaminant ingress because the motor is supplied with a shaft seal. Frame category 025 keeps the overall envelope small for low-inertia loads while remaining compatible with standardized MDD mounting dimensions. This arrangement helps the motor fit compact machine areas where clearance is limited and cable management must remain tidy.
