Product Description:

The MDD041A-N-100-N2K-050MB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. It is intended for use with digital drive controllers where compact, high-speed rotary actuation is required in automated assembly cells, indexing tables, and light machining spindles. By converting finely modulated three-phase current from the controller into mechanical torque, the motor provides controlled motion that fits within restricted mounting envelopes common to multiaxis industrial equipment. Its compact format also suits machine layouts where adjacent axes, cable runs, and guarding leave little free space around the motor body.

A centering shoulder of 50 mm aligns the housing with mating machine frames, while standard dynamic balancing limits vibration during operation. Power and feedback conductors exit on Side B, and a sealed circular connector supports quick exchange without rewiring. This cable arrangement helps keep routing orderly in tightly packed machine sections. The unit sustains a continuous standstill torque of 0.64 Nm, enabling static load holding and low-speed indexing without excess heating. When full voltage is applied, the rotor reaches a nominal speed of 10,000 rpm, making the device suitable for high-speed ancillary axes. Size code 041 and length code A indicate a compact stator stack in the standard aluminum housing, and the drive-side shaft follows the standard geometry without a second shaft on the opposite face.

Position information is generated by an integrated absolute encoder, and the drive processes this signal through resolver feedback for closed-loop velocity and position control. Because the motor is supplied without a blocking brake, external clamping or the drive torque-hold function must be used when power is removed. There is no shaft seal, so the installation area should remain free from liquid spray. A machined shaft with a keyway transmits torque to pulleys or couplings, and the standard housing finish is used without added protective coating.
