Product Description:

The MDD025A-N-100-N2G-040MR1 is a compact synchronous servo motor built by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed for pairing with digital drive controllers, it converts controlled electrical input into rapid rotary motion for auxiliary axes and small positioning modules used in automated production equipment. In this role, it supports precise acceleration and repeatable positioning on compact machine axes where low moving mass and fast response are important. The housing uses a standard ribbed aluminum profile that sheds heat by natural convection.

At its rated operating point, the motor reaches a nominal speed of 10000 rpm, allowing short index times without losing velocity feedback. The stator windings generate 0.33 Nm of continuous torque at standstill, so low-inertia loads can be held under current control alone. A blocking brake is factory installed, and its static capacity of 1.0 Nm prevents back-driving when power is removed. Position information is delivered through resolver feedback, which is resistant to high-frequency electrical noise common in servo cabinets. Accurate flange alignment is supported by a 40 mm centering diameter, and standard dynamic balancing keeps vibration within class limits across the full speed range.

The power and feedback connectors exit on the machine's right side, simplifying cable routing in tight enclosures and matching the controller layout. Overall length remains minimal because of frame code A, and the stator diameter designated size 025 suits compact pick-and-place heads. The single-ended shaft is finished with a keyway and has no side B projection, letting gearheads mount close to the front bearing. Because the unit is supplied without a shaft seal, any sealing against coolant or dust must be provided by the driven mechanism. A molded connector terminal keeps the connection point compact and supports orderly cable routing in confined machine spaces.
