MDD025C-N-100-N2K-040GC0
The MDD025C-N-100-N2K-040GC0 is a small-frame synchronous motor developed by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It serves as a rotary actuator in digital drive systems, linking directly to controllers that require high-speed positioning and stable torque regulation on compact automation axes. By converting electrical commands into mechanical rotation, it supports pick-and-place heads, miniature conveyors, and other precision mechanisms used in industrial equipment. Its small frame also helps where installation space and moving mass must be kept low.
The motor delivers a continuous standstill torque of 0.90 Nm, giving light-load axes enough holding force while limiting heat during long dwell periods. At its nominal speed of 10,000 rpm, the rotor can reach high linear rates when paired with small transmission ratios. Position data is supplied by an integrated absolute encoder, so the drive receives multi-turn position values immediately after power-up. The unit also uses resolver feedback, which provides a sinusoidal signal that resists electrical noise and supports accurate interpolation. Because the motor is supplied without a blocking brake, static holding must be provided by external locking hardware when the axis is parked.
Mounting accuracy comes from a centering pilot of 40 mm on the front flange. All power and feedback conductors exit on Side A, and the factory-terminated connecting cable with coupling unit removes the need for on-site crimping. The output uses a plain shaft with a shaft seal to help keep grease out of the motor interior. A standard shaft end on side A, with no extension on side B, supports close-coupled pulley arrangements. The motor uses size code 025 and length code C, which keeps the housing compact for tight robot joints and other installations with limited space.
