MDD025C-N-100-N2K-040GL0
The MDD025C-N-100-N2K-040GL0 is a compact synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed for digital drive controllers, it delivers precise rotary motion to axes that must accelerate quickly while occupying minimal space in automated assembly equipment, packaging lines, and pick-and-place stations. Its compact size also makes it well suited to short-travel positioning modules and auxiliary handling axes where responsive motion and a small installation envelope are important. This makes the motor suitable for compact servo axes in feeders, transfer units, and small rotary stations that depend on accurate starts and stops.
Its continuous torque at standstill is 0.90 Nm, which is the rotary force it can deliver without movement and the level used for holding duty. At a peak command speed of 10,000 rpm, the rotor can perform rapid indexing moves where short cycle time matters more than heavy load capacity. The centering pilot measures 40 mm, providing an accurate fit to gearheads or mounting flanges and helping keep radial runout low. Power and signal lines connect through a sealed connector on the left side of the stator housing, matching the left connection direction code and simplifying cable routing in tight cabinets. A plain shaft in a standard single-ended arrangement mates directly to couplings or pulleys without added shaft features.
A dedicated shaft seal helps protect the internal bearings against airborne oil and dust in lightly contaminated areas. Position data is returned through resolver feedback, while an integrated absolute encoder provides a multi-turn position value for controllers that need power-on referencing. This feedback arrangement supports closed-loop control during both motion and standstill, helping the axis maintain accurate rotor position under changing load conditions. Dynamic balance is standard, and the C length code in the 025 frame provides additional stack length for higher inertia matching. Because the unit is supplied without a blocking brake, standstill torque for vertical loads must be provided by the drive or an external clamp.
