Product Description:

The MDD025C-N-100-N2G-040MA0 servo unit is produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Built as a motor for digital drive controllers, it translates rapid current vectors from a drive into high-speed rotation for machinery that must start, stop, and reverse in fractions of a second. Its compact frame permits close-coupled installation on light gantries, miniature spindles, or electronic component handlers where space is limited and thermal loads must remain modest.

The motor reaches a nominal velocity of 10000 rpm, so control loops can command very fine positional increments at high cycle rates. A continuous standstill torque of 0.90 Nm keeps loads stable when motion is paused. Shaft alignment during mounting is simplified by a 40 mm centering diameter, and the frame follows size code 025 with length designation C to maintain a consistent footprint across machines that share this platform. It is supplied without a blocking brake, reducing mass when holding force is provided elsewhere in the mechanism. Standard housing and standard dynamic balancing limit vibration, while the single-ended shaft configuration omits a side B extension to shorten the overall rotor. Power and feedback enter through a sealed circular connector on the same side as the motor terminals.

Cabling exits on Side A, allowing conductors to be routed directly toward the cabinet and away from moving parts. Position feedback is delivered by resolver feedback, giving rotor angle signals that remain stable in electrically noisy and high-temperature conditions. Torque is transmitted through a keyway shaft, and the unit is built without a shaft seal. This arrangement suits clean, dry environments where minimal friction is preferred. The connector interface and resolver circuit support stable operation during repeated start-and-stop motion.
