Abstract
An in-line integrated drive generator including a constant speed drive unit having an input shaft defining an axis, an output including a differential on the axis and a control interconnecting the input shaft and the output to cause the output to rotate at a constant speed independent of the speed of a prime mover connected to the input shaft. A brushless generator assembly having a main field structure and an exciter rotor are disposed on the axis and are connected to the output to be driven thereby. A permanent magnet generator for energizing the exciter includes a permanent magnet assembly rotatable about the axis and contained within the constant speed drive unit. The invention provides an in-line drive generator with minimal frontal area as well as a shortened axial length.
