Product Description:

The MDD025C-N-100-N2K-040PA0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it is selected when compact form and very high speed are required in pick-and-place heads, small spindle drives, or packaging axes. The design works with pulse-width-modulated inverters so that velocity loops close quickly and position accuracy is maintained by the integrated feedback system. In factory lines, this motor converts electrical energy into precisely metered torque, letting higher-level PLCs coordinate multiple axes without mechanical gear variation.

The continuous standstill torque is 0.90 Nm, allowing the axis to maintain load force without overheating during dwell periods. A rated speed of 10000 rpm shortens cycle times, while the rotor is balanced to a standard grade to minimize vibration at that speed. The centering pilot measures 40 mm, giving a reference surface for concentric mounting inside tight tooling. Power and feedback conductors exit on side A, and a single multi-pin connector simplifies cabinet wiring. Size code 025 and length code C indicate the active iron volume, matching drive modules that supply the needed current. The housing uses the standard non-cooled design, and the shaft follows DIN keyway geometry so torque is transmitted without slip when coupled to small timing pulleys or flywheels.

Position data is generated through resolver feedback, which tolerates electrical noise and provides reliable rotor angle information to the drive. Mechanical holding force is not provided because the unit is supplied without a blocking brake, so holding torque must come from drive torque or an external clamp during power-off. The output shaft is machined with a keyway and ends at the drive side only, as no side B extension is present. To limit lubricant loss and guard against fine dust, the front bearing area is equipped with a shaft seal.
