MDD025C-N-100-N2G-040GA0
The MDD025C-N-100-N2G-040GA0 is a miniature synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies rotational power for indexing tables, feeders, and other light-duty automation axes. Size code 025 and length code C indicate a short stator stack, which keeps the motor compact while sustaining the rotor inertia needed for rapid control loops. Standard mechanical balancing lets the motor run across its rated speed range without additional trim weights.
Its maximum continuous operating speed is 10,000 rpm, enabling high cycle rates when the matching drive issues frequency-synchronous commands. At standstill, the motor can deliver 0.90 Nm of continuous torque, allowing it to hold small loads without thermal overload. The flange provides a centering recess of 40 mm, which aligns the stator housing with precision mounting fixtures. Power and encoder cables exit on Side A, and a keyed circular connector simplifies cable attachment. A standard cast-aluminum housing conducts heat away from the windings, and the rotor-stator assembly is balanced to a standard grade for smooth motion.
Axial retention is handled by the drive alone because the motor is supplied without a blocking brake. Position feedback is generated by a resolver feedback system, providing analog sine-cosine signals that the controller interprets for rotor position during each revolution. The load is coupled through a plain shaft protected by a lip seal, and the motor is supplied with a shaft seal to help prevent lubricant loss and airborne contaminants from entering the bearings. A standard shaft end on side A and the absence of a side B extension simplify coupling to gearheads or timing pulleys while keeping enclosure dimensions minimal.
