Product Description:

The MDD041A-N-100-N2K-050FB0 is a synchronous motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into rapid rotary motion for indexing tables, compact spindles, and other regulated axes. Its compact design supports servo applications that need accurate speed and position control while using standardized mounting dimensions and electrical interfaces for consistent machine integration.

Mechanical interfaces follow the standard balancing grade, which helps keep rotor vibration within precision-drive limits. The motor centers on a 50 mm pilot for coaxial alignment with gearboxes or direct drives. Power and feedback conductors exit on Side B through a keyed Connector, which helps simplify cable routing in tight cabinets. Under continuous excitation, the rotor sustains 0.64 Nm at standstill, supplying steady holding torque without excessive heat buildup. When the inverter applies full frequency, the shaft reaches 10000 rpm, supporting feeder or spindle duties in compact machines. Size code 041 and length code A keep the housing short while maintaining useful thermal capacity.

Position feedback is delivered by an Integrated absolute encoder, giving the controller position data immediately after power-up. For velocity loops that favor noise immunity, the motor also offers resolver feedback, which can be useful in areas with electromagnetic interference. The unit comes without a blocking brake, so external holding devices must secure static loads during power-off. A standard housing surrounds a plain shaft made without keyways to reduce imbalance, and the opposite shaft end is omitted to save space. Because the motor is supplied without a shaft seal, it is best suited for clean, dry installation areas.
