Product Description:

The MDD041B-N-100-N2G-050PA1 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 receives its excitation and position loops from an external servo amplifier rather than fixed mains frequency. In automated assembly lines, packaging machines, or light spindle stations, the unit converts commanded current into rapid rotary motion while maintaining tight speed regulation, allowing precise interpolation and repeatable cycle times across multi-axis platforms. This makes it suitable for compact motion axes that require responsive acceleration and smooth low-speed operation.

With a motor size code of 041 and a centering diameter of 50 mm, the frame aligns easily to standardized mounting surfaces. Standard balancing limits residual vibration so bearings remain within design life at the rated speed. The rotor can develop a continuous standstill torque of 1.35 Nm, enabling stable holding force during closed-loop positioning. When energized to its nominal rating, the shaft can reach 10,000 rpm, a speed that supports high surface velocities for small tooling or feed rollers. Power and feedback conductors exit on side A, simplifying cable routing in cabinets where drives are stacked vertically.

The housing is supplied in standard form and includes a shaft seal to restrict oil or coolant migration along the output journal. A blocking brake rated at 1.2 Nm is integrated for vertical axes and is released through the same connector that carries phase conductors; the brake engages automatically if control power is lost. Feedback is provided by resolver feedback, which supports high-resolution commutation. The motor uses a keyway shaft end and does not have a secondary shaft on side B. The length code B keeps the overall envelope short, while the detachable connector simplifies installation in modular machines.
