MDD041C-N-100-N2K-050MB0
The MDD041C-N-100-N2K-050MB0 is a compact AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers and supports automation axes that require high-speed positioning and precise torque control. When connected directly to a drive module, it converts commanded current into mechanical rotation for packaging machines, pick-and-place systems, and light machining stations. Its direct-drive layout also helps preserve response and positioning accuracy in short, repeated motion cycles.
The motor sustains a continuous standstill torque of 2.05 Nm, allowing it to hold loads without overheating when locked in position. Its nominal operating speed reaches 10000 rpm, which supports rapid indexing in short-stroke systems. Accurate alignment to gearboxes or mounting faces is aided by a centering diameter of 50 mm. Power and feedback cabling exits on side B, and the primary power interface uses a keyed connector to simplify routing in narrow machine frames. The shaft end follows the standard pattern and omits a secondary shaft on side B, which helps reduce overall length. The motor is supplied without a blocking brake, so any holding function must be provided by the drive or by an external clamp.
Within the series code, the frame size is 041 and the motor length is C. Position sensing is handled by an integrated absolute encoder that reports multi-turn position, while real-time commutation uses resolver feedback for robust sinusoidal signals. This combination gives the drive continuous rotor-angle information for stable control across a wide speed range. The rotor is balanced to the standard grade, and the housing uses the standard version for this motor type. The shaft has no seal, so the installation should prevent coolant or lubricant from entering along the shaft.
