MDD025C-N-100-N2G-040GL1
The MDD025C-N-100-N2G-040GL1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Designed for use with digital drive controllers, the unit supplies closed-loop torque and velocity control for high-speed positioning stages, pick-and-place axes, and light tooling spindles in industrial automation cells. Its compact housing suits installations where space is limited and fast motion is required. The motor also combines feedback and braking functions in one assembly, which helps simplify integration on small machine axes.
The motor delivers a continuous standstill torque of 0.90 Nm, which provides steady holding force for low-speed motion without exceeding thermal limits. During operation, it can reach a nominal speed of 10000 rpm, which suits fast indexing routines and short cycle periods. A blocking brake applies 1.0 Nm of torque when engaged, helping hold vertical axes during power loss or stops. Rotor position is reported through resolver feedback, allowing the drive to track the shaft angle reliably in electrically noisy environments. Mechanical coupling is handled by a plain shaft, which works with press-fit couplings or collets and avoids the added mass of a keyway.
A centering pilot of 40 mm helps seat the motor accurately against the mounting face. Power and feedback leads exit on the left side through a sealed connector, which helps keep cable routing clear of nearby moving parts. The motor uses frame size 025 with length code C, giving it a short overall body for compact machine layouts. A shaft seal is installed to limit the entry of coolant or dust, and the shaft is provided only on the drive side in the standard single-shaft arrangement. The standard aluminum housing supports even heat transfer to the surrounding air while the balanced rotor helps maintain smooth running at high speed.
