MDD025A-N-100-N2K-040FA0
The MDD025A-N-100-N2K-040FA0 is a miniature synchronous motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is intended for use with digital drive controllers, where it converts commanded current into controlled torque for precise rotary motion. This makes the motor suitable for semiconductor handling equipment, laboratory automation, and other compact systems that require fast response with light loads. Its small form factor and standardized interface help it fit tightly packaged motion assemblies without adding unnecessary complexity to the axis layout.
At a continuous standstill output of 0.33 Nm, the motor can hold position or perform slow indexing while remaining within normal thermal limits. A nominal speed of 10000 rpm supports short motion cycles and rapid repositioning when the drive is matched correctly to the load. The centering shoulder measures 40 mm in diameter, which helps the motor seat accurately on mating flanges and maintain concentric alignment. Power and feedback conductors exit on Side A, which keeps cable routing consistent on compact machine faces. A single connector carries the electrical interface, reducing the need for separate terminal hardware and keeping the external connection point straightforward.
Rotor position is measured by resolver feedback, and an integrated absolute encoder provides immediate shaft-angle information after power-up. This arrangement supports closed-loop control and allows the drive to recognize position without a homing move at startup. The motor uses a plain shaft, which allows couplings or pulleys to be fitted without a keyway interface. It is supplied without a shaft seal, so the application should be kept away from direct fluid exposure or protected with external sealing when used in wet or washdown areas. That shaft arrangement is best suited to clean, dry installations where low-friction power transmission is preferred.
