MDD025C-N-100-N2K-040GF1
The MDD025C-N-100-N2K-040GF1 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed as a compact drive element for digital drive controllers, it supports rapid rotary positioning in automated machines and material-handling stations. When paired with a compatible drive controller, it closes the torque and speed loops electronically rather than through mechanical adjustment. This motor is suited for applications that require high spindle speed along with stable low-speed holding capability.
At its nominal speed of 10,000 rpm, the rotor can follow fast command changes while the standard balancing grade helps limit vibration transferred into connected mechanics. A continuous torque of 0.90 Nm is available at standstill, so the axis can maintain preload without thermal overload. During power-off states, the integrated blocking brake applies 1.0 Nm of static torque to help prevent back-driving on vertical axes. Mounting is centered by a 40 mm pilot that supports coaxial alignment with the driven load. Power and feedback leads exit on the right side, and a connecting cable with a coupling unit supports plug-in installation where panel space is limited.
Position sensing begins with an integrated absolute encoder that supplies single-turn data for closed-loop control. For applications that require angle monitoring, a secondary channel provides resolver feedback. The motor uses a plain shaft as the mechanical output, and the end opposite the load remains closed in the standard shaft-end arrangement. A design with a shaft seal helps retain lubrication and reduce contaminant entry. The housing is supplied in the standard configuration, and the C length in frame size 025 provides a longer stator stack with additional thermal mass without increasing the flange footprint.
