MDD025C-N-100-N2K-040PE0
The MDD025C-N-100-N2K-040PE0 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical input from an inverter into precise rotary motion. In automated packaging stations, pick-and-place heads, or light assembly axes, it supplies rapid speed changes and repeatable positioning so that machine cycles remain synchronized with command profiles.
Its nominal speed reaches 10000 rpm, so the rotor can run at rated voltage while staying within thermal limits. When the shaft is locked, the motor can develop 0.90 Nm of continuous torque, which helps size the drive amplifier output and check static load requirements. The rotor uses standard balancing, so vibration stays within normal tolerances during high-speed service. A centering diameter of 40 mm provides the locating fit in the mounting flange, simplifying alignment with gearbox or frame bores. Power and feedback conductors exit on the left side, allowing cables to be routed away from adjacent axes. The unit is supplied without a blocking brake, so external mechanical holding is needed if position retention during power-off is required.
Signal integrity is enhanced by the integrated absolute encoder, which delivers single-turn position data to the controller without homing moves. For commutation, the motor also uses resolver feedback, which provides analog angle information that remains functional at elevated temperatures and speeds. The output shaft has a keyway to transmit torque into couplings or pulleys, and a surrounding shaft seal helps block lubricant or dust from entering the housing. The C length code, standard housing, connection cable with coupling unit, and single-ended shaft allow the motor to fit compact Z-axes or spindle drives where low mass and high rotational speed are needed.
