MDD041B-N-100-N2K-050FB1
The MDD041B-N-100-N2K-050FB1 is a motor for digital drive controllers manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended to translate electrical commands from servo amplifiers into high-speed rotary motion for tasks such as pick-and-place heads, small spindle drives, and compact positioning axes in automated production cells. Its compact format suits machine sections where installation space is limited, while still supporting the fast response expected from small servo-driven axes.
This model supplies a continuous standstill torque of 1.35 Nm, so the shaft can hold a load without movement while energized. During normal operation, the rotor can reach 10000 rpm, enabling rapid cycle times in low-inertia systems. Precise mechanical centering is achieved through a 50 mm pilot diameter that aligns the stator with adjoining machine frames. All power and signal conductors exit on Side B, allowing cable routing toward the rear of a slide or column. That exit direction can simplify cable routing when the motor is mounted near guarding or slide assemblies. Position data is delivered by an integrated absolute encoder, giving the controller immediate knowledge of shaft angle after power-up and removing the need for a homing routine.
Additional functional elements shape how the motor behaves once mounted. A blocking brake generates 1.2 Nm of holding torque, keeping vertical or safety-critical axes fixed when the drive is disabled. The drive electronics can also use resolver feedback for velocity and commutation control through a separate signal set. The rotor terminates in a plain shaft, simplifying coupling to pulleys or collets, and the front bearing section is shipped without a shaft seal, an arrangement suited to clean, enclosed environments where fluid ingress is not expected. Standard housing geometry, size code 041, and length code B help the motor fit established mounting patterns and related drive system layouts.
