Product Description:

The MDD025B-N-100-N2G-040FL1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. With a slender 025 frame and B length code, this unit fits compact mechanical stages where installation space is limited. It pairs with digital drive controllers to convert precisely modulated three-phase currents into controlled rotary motion for indexing tables, pick-and-place heads, and miniature packaging spindles across automated lines. The motor is intended for applications that need rapid speed changes, accurate positioning, and a compact servo package.

At the mounting face, the centering diameter measures 40 mm, aligning the motor concentrically with precision gearboxes. Cables exit on the left side by way of a keyed connector, so the housing can sit flush against adjacent equipment and cable routing can stay clear of nearby machine parts. The rotor can supply 0.60 Nm of continuous torque at standstill for tensioning or steady holding duties, and when commanded it accelerates to a nominal speed of 10000 rpm for high-throughput positioning cycles in small-axis motion systems. A blocking brake built into the rear frame delivers 1.0 Nm of holding torque during power-off events, which helps hold the axis in place when motion is stopped. Standard dynamic balancing and the standard housing keep vibration levels low while the drive operates across its full thermal range.

Angular position is sensed by resolver feedback, providing absolute sine-cosine signals that tolerate electrical noise at high rotational rates and support stable commutation. The output side uses a plain shaft, which supports direct coupling with miniature pulleys or friction wheels in compact drive trains. The motor is supplied without a shaft seal, which reduces drag where environmental contaminants are not present. This arrangement suits clean machine zones where low friction and small external dimensions are more important than sealed shaft protection.
