MDD025B-N-100-N2G-040GL1
The MDD025B-N-100-N2G-040GL1 is a small-frame synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. In automated machinery, this unit converts controlled electrical drive signals into precise rotary motion for positioning axes, feeders, and light pick-and-place devices that rely on digital drive controllers. Its compact 025 frame and standard housing permit installation in restricted mechanical bays without changing surrounding machine geometry. The motor is well suited to compact assemblies where short-travel axes, small couplings, and limited mounting space require accurate motion from a very small package.
At standstill the rotor can deliver 0.60 Nm of continuous torque, allowing stable holding or slow-speed regulation without excessive temperature rise. During operation it reaches a nominal speed of 10,000 rpm, supporting applications that need high peripheral speed within a minimal footprint. A precision-machined 40 mm centering diameter registers the stator on the mounting face so alignment shims are rarely required. Electrical power, resolver, and brake lines exit through a left-side connection, reducing cable loops when drives are mounted to the right of the axis. Position feedback comes from resolver feedback, which provides sine-cosine signals that remain reliable in electrically noisy environments. This feedback method also gives the drive the rotor position information needed for stable commutation across the speed range.
For static safety on vertical or interrupted cycles, the motor includes a blocking brake rated at 1.0 Nm. A plain shaft paired with a factory-installed shaft seal helps limit grease escape and reduce the entry of fine dust into the bearing chamber. Dynamic behavior benefits from standard balancing, which helps keep vibration low as the rotor accelerates through its operating range. The shaft and seal arrangement also supports use in enclosed machine sections where clean running and consistent bearing protection are important.
