Product Description:

The MDD025C-N-100-N2G-040PE0 is a synchronous motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts inverter output into mechanical rotation for positioning or velocity-regulated axes in industrial automation. The unit follows size code 025 and length code C, creating a compact active stack well suited to small manipulators and spindle drives where elevated speed is required.

Mechanical mounting data dominates the second group of parameters. A centering shoulder of 40 mm aligns the housing to the machine frame and keeps radial runout low. Cable glands aim to the operator’s side because the connection hardware is oriented to the Left. Power and feedback conductors are bundled in a Connecting cable with coupling unit, which simplifies removal during service. At standstill the motor can produce 0.90 Nm continuously, so thermal limits are not exceeded during holding tasks. The rotor is shipped without a blocking brake; therefore external clamping or active torque from the drive must secure vertical loads.

Control and environmental features finalize the profile. The resolver provides sinus-cosinus position signals, identified as Resolver feedback, enabling analog absolute angle evaluation by the drive controller. A designed top speed of 10000 min⁻¹ supports high-frequency tool or spindle cycles while matching the torque curve of the 025 stator. Leakage paths are restricted by construction with a shaft seal, allowing installation where coolant mist or dust is present. Power is transmitted through a shaft machined with a keyway, and the absence of a side-B shaft end keeps overhung mass low; balancing remains standard and the housing follows the common enclosure pattern for this series.
