MDD025A-N-100-N2G-040GL0
The MDD025A-N-100-N2G-040GL0 is a compact synchronous servo motor from Bosch Rexroth Indramat in the MDD Synchronous Motors series. Designed for digital drive controllers, it serves as the rotary actuator in positioning, indexing, and contour-following axes used in assembly cells and light machining centers. The motor operates in closed-loop motion systems where high speed and stable velocity control are required. Its mechanical envelope corresponds to size 025 with length code A, making it suitable for miniature direct-drive applications.
This model reaches a nominal speed of 10000 rpm, allowing fast cycle times on short-stroke mechanisms. Under continuous stall conditions, it can deliver 0.33 Nm of torque, which is the maximum load it can hold without rotation when the controller keeps the shaft locked. A centering diameter of 40 mm provides the reference fit between the flange and the machine frame for accurate axial alignment. Power and feedback conductors exit on the left side because the electrical connector is molded into that face of the housing. Standard dynamic balancing and a standard enclosure help reduce vibration while keeping mass low for rapid acceleration.
Signal quality is maintained through resolver feedback, which provides rotor position information during rapid reversals. The motor uses a smooth plain shaft protected by a shaft seal, helping keep light oil mist or dust away from the bearing area. For applications that need power-off restraint, external holding devices are required because the motor is supplied without a blocking brake. The shaft is provided only on side A, which leaves the rear face clear where a compact mounting arrangement is needed. A standard aluminum housing with the 025 frame profile and A length helps keep overall weight low for direct attachment to miniature gearheads or belt pulleys.
