An undesirably long brushless generator including a permanent magnet generator 114, 116, 118, an exciter 64 and a main generator 22, 24, 42, 44 may have its axial length reduced by locating both the permanent magnet generator 114, 116, 118 and the exciter 64 adjacent one end of the main generator 22

An undesirably long brushless generator including a permanent magnet generator 114, 116, 118, an exciter 64 and a main generator 22, 24, 42, 44 may have its axial length reduced by locating both the permanent magnet generator 114, 116, 118 and the exciter 64 adjacent one end of the main generator 22, 24, 42, 44 in an essentially coplanar relation with the permanent magnet generator 114, 116, 118 radially inward of the exciter 64.
