Product Description:

The MDD025C-N-100-N2G-040PD0 synchronous servo motor is built by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts inverter-driven stator currents into mechanical rotation for small axes that demand high-speed positioning in automation cells and pick-and-place modules. Its compact 025 frame, standard housing, and integrated shaft seal allow installation inside enclosed machinery without separate environmental covers.

Mechanical geometry starts with a centering diameter of 40 mm, ensuring coaxial alignment with gearheads or flange plates. Power and feedback conductors emerge on Side B, so cabinet layouts must leave clearance on that face. The motor is supplied with a connecting cable with coupling unit; this preassembled lead simplifies field replacement and maintains shielding continuity. At standstill the electromagnetic system can deliver 0.90 Nm of continuous torque, enough to drive light indexing tables without overheating. Under rated excitation the rotor reaches 10000 min⁻¹, a high nominal speed that permits direct coupling to small-diameter timing pulleys and minimizes mechanical ratios.

Position accuracy is improved by the integrated resolver feedback, which reports absolute shaft angle to the drive so commutation is maintained even after a power cycle. The keyed shaft uses a keyway profile, giving positive torque transfer to couplings while the fitted shaft seal keeps lubricant and contaminants separated. Because the motor is delivered without a blocking brake, designers must provide external holding force when vertical axes are parked. Dynamic characteristics are further defined by standard balancing, the slim C length code, and a standard shaft end on the non-drive side, all of which keep inertia low for responsive acceleration.
