Product Description:

The MDD041A-N-100-N2G-050FB0 is a synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for use with digital drive controllers, it delivers rapid torque buildup and high rotor speed for precision positioning or velocity control in compact automation axes. The unit follows the series' standard housing and balancing conventions and is supplied without a blocking brake, making it suitable for installations where the drive itself or an external mechanism secures the load during power-off states.

A continuous standstill torque of 0.64 Nm indicates the sustained load the motor can hold without overheating when the shaft remains locked. Under rated excitation, the rotor reaches a nominal speed of 10000 rpm, enabling direct coupling to high-speed transmission stages or low-inertia tooling. The centering shoulder measures 50 mm in diameter, aligning the stator to precision mounting surfaces and helping keep runout error low. Size code 041 and length code A create a short stack that reduces mass and rotor inertia, allowing fast acceleration. Standard dynamic balancing keeps residual vibration low, while the plain-ended shaft can accept clamps or bonded pulleys without additional machining.

Power and feedback connectors are oriented toward Side B of the housing and use a single industrial Connector interface. Angular position and velocity are reported through integrated Resolver feedback, permitting analog or interpolated digital tracking by the drive. The rotor exits the housing as a Plain shaft, and the front bearing zone is supplied without a shaft seal; this arrangement minimizes drag but requires protection from coolant or particulate ingress at the coupling face. The shaft is finished only on the drive end, with no extension on side B.
