MDD041C-N-100-N2K-050PB0
The MDD041C-N-100-N2K-050PB0 is a compact AC synchronous motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts stator-mounted drive signals into mechanical rotation for high-speed positioning and feeding axes in automated assembly lines. Its compact size suits machine layouts that need fast axis response without requiring a large motor envelope. This type of motor is commonly used where rapid indexing and repeatable motion are required, such as feeders, transfer units, and compact handling systems.
The unit reaches a nominal speed of 10,000 rpm, permitting direct coupling to fast linear stages without external gear reduction. Direct coupling at high speed can reduce drivetrain complexity and avoid backlash introduced by external reduction stages. At standstill it can supply 2.05 Nm of continuous torque, which helps the axis maintain commanded position while the controller holds zero speed. Accurate alignment to the machine frame is supported by the 50 mm centering diameter, and standard dynamic balancing minimizes vibration over the full speed range. Power, feedback, and brake leads exit on Side B, and the single-plug connector interface simplifies cable routing inside compact cabinets. A hardened steel shaft with a keyway transmits torque, and the 041 frame size and C length code indicate the active magnetic stack used to produce the motor's torque-to-inertia ratio.
Position data are delivered through resolver feedback, while an integrated absolute encoder supplies multi-turn information for drives that need homing-free startup. The motor is supplied without a blocking brake, so external mechanical locks or drive torque must secure vertical loads when power is removed. A positive-pressure shaft seal and a standard housing protect the bearing set from coolant splash and dust. The shaft end remains standard on the drive face with no extension on side B, which supports tight mounting envelopes. This feedback arrangement supports closed-loop control across a wide speed range.
