MDD025C-N-100-N2K-040FF0
The MDD025C-N-100-N2K-040FF0 belongs to the MDD Synchronous Motors series from Bosch Rexroth Indramat. It is a compact servo motor intended for digital drive controllers where high spindle speeds and tight positional accuracy are required. Within an automation cell, this motor converts drive commands into mechanical rotation so that tooling, handling axes, or auxiliary actuators can follow precise speed and position profiles without additional gearing. Its compact format makes it suitable for installations where mounting space is limited but accurate motion control is still required.
The motor can develop a continuous standstill torque of 0.90 Nm, giving small indexers or grippers enough holding force while stationary without overheating. Under rated excitation, it reaches a nominal speed of 10000 rpm, allowing fast cycle times in pick-and-place or lightweight spindle duties. A centering diameter of 40 mm aligns the housing concentrically with the machine frame, which helps reduce radial runout during operation. Electrical and feedback leads exit on the right side, so cable routing can stay on one machine face and remain easier to organize. Power is delivered through a connecting cable with a coupling unit, which creates a secure interface between the motor and its cable set. This arrangement avoids loose terminal-style connections and supports stable electrical continuity during repeated motion.
Resolver-based control is enabled by the built-in resolver feedback, letting drive electronics track rotor angle at high speed with strong noise resistance. For higher-resolution startup referencing, an integrated absolute encoder is also present and stores position data for one mechanical revolution. The motor ships without a blocking brake, so holding torque must be supplied by the drive or by external mechanical means when power is off. The output uses a plain shaft, which simplifies coupling selection for low-torque duties and avoids the added profile of keyed or splined versions. This combination of feedback devices supports both stable running behavior and accurate position recovery after power-up.
