MDD025C-N-100-N2K-040MR1
The MDD025C-N-100-N2K-040MR1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts regulated electrical power into precise rotary motion for axes that demand rapid acceleration and repeatable positioning in automated assembly or small spindle applications. Its compact format suits tightly spaced machine layouts where accurate servo response is required without a large motor envelope. When paired with a suitable controller, the motor supports accurate speed regulation and repeatable position correction during frequent starts and stops.
The unit delivers a continuous standstill torque of 0.90 Nm, allowing the drive to hold a load steadily without thermal overload. During motion, it can reach a nominal speed of 10000 rpm, which suits high-cycle machinery and short move times. A blocking brake is integrated and provides 1.0 Nm of torque to secure the shaft when power is removed. This arrangement helps keep a parked axis from drifting between machine cycles. Position feedback is generated by an integrated absolute encoder, so the controller receives position data immediately after startup, and this can reduce the need for reference moves after a restart. Mounting accuracy is aided by a 40 mm centering diameter, and the standard balancing class helps support smooth rotation during operation.
Electrical and signal lines attach through a compact connector oriented to the right side, which helps with cable routing in narrow cabinets. The rotor shaft has a keyway and uses the standard single-ended configuration, so there is no side-B shaft extension. The single-ended layout can simplify coupling arrangements where rear clearance is limited. The motor is supplied with no shaft seal, so the installation area must be kept free of fluid ingress and heavy contamination. A dry installation environment helps protect the exposed shaft area during long-term use. The motor size code is 025, and the standard housing profile keeps the external form consistent with other motors in the same frame family.
