Product Description:

The MDD025C-N-100-N2K-040FD1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied as a motor for digital drive controllers, where it converts controller current into controlled rotary motion for positioning and feed axes in automated equipment. An integrated absolute encoder provides immediate position data after power-up, and the unit includes a blocking brake for load securing when the drive is disabled.

The motor delivers a continuous standstill torque of 0.90 Nm, giving it the ability to hold static loads without thermal overload. Its nominal operating speed reaches 10000 min⁻¹, enabling high-cycle machining or assembly routines when paired with a compatible inverter. During shutdown, the blocking brake applies 1.0 Nm of holding torque to keep the shaft locked. All power and feedback conductors exit on Side B, reducing cable congestion on the machine front. A centering diameter of 40 mm defines the reference seat that aligns the standard housing with mounting fixtures, ensuring repeatable mechanical registration.

Rotor position is monitored through resolver feedback, which supplies continuous angle information even during rapid reversals. With a compact frame size code of 025 and motor length code C, the unit fits installations where depth is limited. Output torque is transmitted through a plain shaft; the design omits a second shaft end to save space and mass. Because the construction is without shaft seal, the installation must shield the front bearing from direct liquid spray. Standard balancing limits vibration at full speed, and electrical power is routed through a connecting cable with coupling unit that mates quickly during service.
