MDD025C-N-100-N2K-040PD1
The MDD025C-N-100-N2K-040PD1 is a compact synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts commanded stator currents into precise rotor movement for pick-and-place heads, miniature spindles, and other fast-cycling axes. A standard housing and standard dynamic balancing allow installation without additional vibration treatment. The integrated absolute encoder supplies multi-turn position data immediately after power-up, so the drive can begin controlled motion without a separate homing cycle. This is useful on compact handling axes where repeated reference moves would reduce available travel and slow machine operation.
Mechanical mounting is centered on a 40 mm pilot, which helps seat the motor accurately on the mating surface. The motor sustains 0.90 Nm of continuous standstill torque, providing holding force for lightweight loads while energized. High-speed operation is supported by a nominal speed of 10000 rpm, so short-cycle stations can reach working speed quickly. Power and sensor conductors exit on side B, and a connecting cable with a coupling unit supports straightforward installation and compact cable routing. Resolver feedback operates alongside the absolute encoder to supply position and speed information during closed-loop control, and the standard shaft end omits a rear extension to keep the motor body short.
A blocking brake rated at 1.0 Nm helps prevent axis drift when power is removed, which is useful on vertical or suspended loads. The shaft has a keyway for positive torque transmission and a shaft seal that helps protect the bearing area from splash and dust. Length code C identifies the longer housing within the 025 frame, giving room for the magnetic stack while keeping the package compact enough for small machine assemblies. The standard housing and compact format also suit installations where adjacent components leave only limited clearance around the motor body.
