What type of system do Integrated Drive Generators (IDGs) utilize to produce current?

Integrated Drive Generators (IDGs) are designed to produce electrical power using a brushless system. This design is particularly advantageous in aviation applications, where reliability and maintenance considerations are critical.

In a brushless system, the generator does not use brushes for current transmission, which reduces wear and tear, lowers maintenance requirements, and increases the longevity of the components. The rotor typically produces a magnetic field that induces current in the stator windings. Because there are no brushes, there is a significant reduction in electrical noise and sparking, leading to improved system stability and reduced risk of electrical failures.

This brushless design provides enhanced efficiency and performance, making IDGs well-suited for the demanding conditions found in avionic environments where high reliability is essential.
