Product Description:
The MDD041C-N-100-N2G-050MA0 is a servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is supplied as a drive element for digital drive controllers that require compact dimensions and high spindle speeds in automated assembly, electronics handling, and light machining cells. The motor converts controlled electrical power into precise rotary motion so that position and velocity commands issued by the controller can be carried out without mechanical transmission backlash. This arrangement supports accurate starts, stops, and speed changes on compact machine axes.
The rotor is dynamically balanced to a standard grade, and its centering flange measures 50 mm, allowing direct alignment with gearboxes or mounting brackets. Power and feedback conductors exit on Side A, which simplifies cable routing when the machine layout keeps the motor’s rear face accessible. A circular connector carries phase power and resolver signals, eliminating loose wiring. At standstill, the electromagnetic circuit sustains 2.05 Nm of continuous torque, a level suited for indexing loads such as small pick-and-place grippers or spindle positioning tables. Housing surfaces follow the standard MDD profile, so thermal dissipation relies on ambient airflow, and the C length uses a longer stator stack in the 041 frame to increase torque density without increasing diameter.
During motion, the motor reaches a nominal speed of 10000 rpm, enabling high throughput in short-stroke applications. Rotor position is reported through resolver feedback, giving the controller rotor angle information under electrical noise and temperature variations. The ground shaft is machined with a keyway to transmit torque into couplings without slippage, and the design is shipped without a blocking brake, so external holding devices must secure vertical axes. A standard shaft end is fitted only on the drive side, and the front bearing region is supplied without a shaft seal, so the motor is best suited for clean, dry environments.
