Product Description:

The MDD025B-N-100-N2G-040GB1 is a compact synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to work with digital drive controllers, it delivers commanded torque to light industrial axes that demand rapid acceleration and repeatable positioning. The 025 frame size, B length code, standard housing, and standard rotor balancing allow the unit to be mounted in close proximity to other machinery without additional counterweights or guards, making it suitable for dense assembly and semiconductor tooling lines.

At the electrical interface, the motor reaches a nominal speed of 10,000 rpm, so it can follow high-frequency motion profiles without mechanical overshoot. Continuous stall torque is 0.60 Nm, providing steady force for holding or low-speed feed duties while staying within thermal limits. Accurate centering during installation is aided by a 40 mm pilot diameter that matches standard flange patterns. Power and feedback conductors exit on side B, and the single multi-pin connector simplifies cable routing through tight enclosures. Together with the 025 frame, this connection scheme helps shorten the installation depth, reduce wiring strain, and keep electromagnetic noise away from neighboring modules.

For static holding, the integrated blocking brake supplies 1.0 Nm of torque to prevent drift when the drive is disabled or during emergency stops. Position information is returned through resolver feedback, giving continuous angle data that resists electrical noise and high acceleration. The motor uses a mechanically ground plain shaft and operates with a shaft seal to limit lubricant migration and shield the bearings from fine dust common in automated pick stations. A standard shaft end on the drive side and the absence of a second shaft on side B leave room for couplings or miniature timing pulleys, making the motor suitable for use with precision gearheads and linear stages without adding unnecessary mass or complexity.
