MDD025C-N-100-N2K-040PB0
The MDD025C-N-100-N2K-040PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. It is intended for use with digital drive controllers and suits high-speed positioning tasks in automated machinery. In servo systems, it converts commanded electrical current into precise rotary motion for fast indexing and repeatable positioning. The motor is size 025 with length code C, which gives it a compact envelope while retaining a standard housing and standard dynamic balancing. A shaft seal protects the output area from contamination, and the motor uses a single shaft end rather than a second shaft on side B.
This motor reaches a nominal speed of 10000 rpm, which supports short cycle times in pick-and-place or spindle applications. At standstill, it produces 0.90 Nm of continuous torque, so the drive must sustain that thermal load during locked-rotor operation. The centering flange is machined to 40 mm for accurate alignment with gearboxes or machine frames. Power and feedback conductors exit on side B, and the unit uses a plug-in connector so cabling can be connected without opening the housing. The rear cable exit leaves the flange area clear for close mounting to adjacent mechanical components.
An integrated absolute encoder supplies position data at power-up, and it works with resolver feedback to support continuous speed control. That combination lets the controller retain position information after startup while maintaining stable speed feedback during operation. The motor is delivered without a blocking brake, so load holding must be provided by the drive or external mechanics when the axis is stopped. The shaft has a keyway for direct torque transmission to pulleys or couplings. Standard dynamic balancing helps limit vibration at high speed, which supports smooth running in clean, enclosed industrial equipment.
