Product Description:

The MDD025C-N-100-N2G-040FC1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is designed to couple with digital drive controllers and provide closed-loop torque and speed control on compact axes in packaging machines, pick-and-place modules, and small gantries. By integrating a blocking brake, it holds stationary loads whenever the drive is disabled, allowing the axis to keep position without external clamping.

This motor delivers a continuous standstill torque of 0.90 Nm, a rating that defines the mechanical load it can support indefinitely without overheating while the rotor is locked. During motion it reaches a nominal speed of 10000 min⁻¹, enabling fast indexing where cycle time is critical. The internal brake supplies 1.0 Nm of holding torque so vertical or suspended loads remain fixed after power is removed. A centering diameter of 40 mm aligns the flange precisely on a mounting surface, ensuring concentricity between the motor shaft and driven mechanics. Standard dynamic balancing limits vibration at high speed, and the standard housing keeps the overall envelope compatible with other size-025 frames. Because the shaft end is supplied only on side A, designers can mount a coupling or pinion without interference on the rear face.

Connection hardware routes out the front of the terminal box on Side A and uses a connecting cable with coupling unit to minimize panel wiring. Position feedback is generated by a resolver feedback device, allowing analog angle information to reach the drive for vector regulation. The stator follows the 25 mm frame convention, noted as motor size 025, while the “C” length code extends the active iron to increase torque reserve without altering diameter. A plain shaft is supplied, and there is no shaft seal, so the installation must prevent coolant or oil ingress at the bearing zone.
