Today we will take look on vital component of Airbus A320 engine CFM56-5B and it is IDG.
Each engine (HP rotor) drives its associated IDG through the accessory gearbox. The drive speed varies according to the engine rating.
The IDG provides a 115/200 VAC, 3-phase, 400 Hz AC supply at the Point of Regulation (POR).
The IDG has two parts: the Constant-Speed Drive (CSD) and the generator.
The hydromechanical Constant-Speed Drive drives the AC generator at constant speed.

Function of the IDG Pushbutton Switches
If an IDG is faulty (overheat or abnormal oil low pressure), the FAULT legend comes on. The pilot must then open the safety guard and push the IDG pushbutton switch. This action results in the mechanical disconnection of the faulty IDG.
NOTE:
With engine stopped, the IDG cannot be disconnected. An underspeed condition inhibits the disconnection.

And since you know how this system works, let me show you how to replace one of the lead
