Frequently Asked Questions
What performance advantages define the MDD090C-N-030-N2G-110GB0 servo motor?
The motor provides a nominal torque of 10.4 Nm and a peak torque of 31.2 Nm, enabling excellent acceleration and precise load handling. This combination supports smooth torque transitions critical for synchronized multi-axis systems.
How does the 0.46 Ω winding resistance influence the MDD090C-N-030-N2G-110GB0 efficiency?
The low winding resistance minimizes copper losses and thermal buildup under sustained current loads. This contributes to higher energy efficiency and allows tighter thermal management in compact enclosures.
Why is the 53 × 10⁻⁴ kg·m² rotor inertia essential for servo precision?
This moderate inertia offers a refined balance between responsiveness and stability during acceleration and deceleration phases. It enhances control fidelity, particularly in high-speed indexing or contouring operations.
How does the 45-minute thermal time constant affect continuous-duty applications?
The extended thermal time constant ensures gradual temperature rise during operation, maintaining winding integrity over prolonged duty cycles. This is especially valuable in 24/7 automation cells with limited cooling capacity.
What benefits arise from the 3000 rpm nominal speed and 9.4 A current rating?
This configuration delivers a wide dynamic range suitable for precision motion profiles without excessive current draw. It enables efficient integration into high-speed machine tools and robotics with minimal overshoot risk.
