Product Description:

The MDD041B-N-100-N2K-050FA0 is an AC synchronous motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it supplies precisely regulated torque and speed for pick-and-place modules, packaging axes, and other compact automation stages that demand rapid rotary motion. The model’s 041 frame and B-length body allow close mounting to linear guides or gearbox flanges, while its standard housing protects the stator windings without unnecessary bulk. This combination is suited to compact servo axes where installation space is limited, cable runs are short, and accurate motion control is required throughout repeated indexing and positioning cycles. It is intended for applications that need quick response without moving to a larger motor frame.

A centering diameter of 50 mm provides a repeatable register for face mounting, and all power and feedback plugs exit on Side A through a single connector to simplify cable routing. At standstill, the motor sustains 1.35 Nm of continuous torque, and it can spin up to 10000 rpm when the drive supplies rated current and frequency. Because the unit is supplied without a blocking brake, position holding during power loss must come from drive torque or an external clamping device. Balancing is set to the standard grade to help limit vibration, and the lack of a shaft seal means the shaft passage should be protected from fluid ingress when needed.

An integrated absolute encoder reports position immediately after power-up, while secondary resolver feedback channels provide analog angle data for drives that use it. Motion is transferred through a plain shaft that omits keyways to reduce stress concentrations, and the motor follows the dimensional envelope of motor size 041 with length code B. Connections use a keyed circular connector, and the unit is supplied without a shaft seal or side-B shaft extension to reduce overall length. The single-ended shaft arrangement also keeps the package compact for installations that place the motor close to adjacent bearings, couplings, or guide components.
