MDD025C-N-100-N2G-040GD0
The MDD025C-N-100-N2G-040GD0 is a synchronous servo motor produced by Bosch Rexroth Indramat in the MDD Synchronous Motors series. As a motor designed for digital drive controllers, it converts commanded drive signals into precise rotary motion for indexing tables, small actuators, and packaging axes in automated lines. Compact motor size 025 with length code C allows the unit to fit into tight machine spaces without sacrificing the fast response needed for short positioning moves. It is suited to compact servo applications where accurate starts, stops, and repeatable speed control are required during frequent operating cycles.
Its mechanical interface begins with a centering diameter of 40 mm, which keeps the motor flange aligned with the machine frame during installation. Electrical and feedback conductors exit on Side B, which can simplify cable routing when the drive cabinet is behind the axis. A plain shaft without keyways supports direct-coupled loads that use clamp collars. Under continuous stall conditions, the rotor can supply 0.90 Nm of torque, and during motion it reaches a nominal speed of 10,000 rpm for light-duty, high-speed positioning tasks. Standard dynamic balancing and a standard housing support straightforward mounting without special vibration or sealing changes.
Motion signals are provided through resolver feedback, which gives the controller rotor angle information during rapid acceleration and deceleration. Power and resolver leads exit through a connecting cable with coupling unit, allowing the motor connection to be separated without opening a terminal box. The motor is supplied without a holding brake, so the axis must rely on drive torque or an external clamp to hold position when power is removed. A radial shaft seal sits behind the front bearing to help block dust and lubrication spray from entering the interior.
