MDD041C-N-100-N2K-050FA1
The MDD041C-N-100-N2K-050FA1 is a compact synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it translates commanded current into high-speed rotary motion that can be synchronized with position loops in automated machinery, packaging axes, and pick-and-place modules. The unit targets installations that demand rapid positioning from a lightweight frame while remaining mechanically compatible with standardized Indramat mounting interfaces and cabling. It integrates an absolute encoder so the controller can read the shaft angle immediately after power-up without a homing move. This combination suits compact automation cells where fast starts, stops, and repeatable positioning are required during normal production cycles.
The stator face includes a centering pilot of 50 mm for accurate alignment to adjoining gearboxes or fixtures, and the rotor is balanced to the manufacturer’s standard class. A nominal operating speed of 10000 rpm supports fast travel profiles, while a continuous standstill torque of 2.05 Nm supports load holding without thermal overload. Power and feedback conductors exit on side A, and a single connector groups all terminations to simplify wiring in confined cabinets. With frame size code 041 and length variant C, the motor body keeps inertia low while providing enough active iron for the listed torque output. A standard cast housing encloses the windings and supports natural convection cooling. Natural convection also avoids the need for separate fan hardware, which helps keep the installation layout simple.
Motion is transferred through a plain shaft in a single-ended configuration, so no side-B shaft extension interferes with adjacent components. A blocking brake rated at 1.2 Nm secures the axis when power is removed, which is useful on vertical or suspended loads. The shaft area is without a shaft seal, so external splash protection may be needed in wet areas. This arrangement also helps the motor fit close to neighboring machine parts where clearance is limited.
