Embodiment Construction

[0017] figure 1 A functional block diagram of one embodiment of the starter-generator system 20 is schematically shown. The exemplary starter / generator system 20 is commonly referred to as a brushless AC starter / generator and includes a permanent magnet generator (PMG) 22 , an exciter 24 , a main / generator 26 , a starter / generator control unit 28 and one or more rectifiers 30 . The starter / generator system 20 may be used as a starter-generator for a gas turbine engine in aircraft applications, aerospace applications, marine applications, land applications, or other transportation-related applications in which a gas turbine engine is used. For aircraft applications, gas turbine engines are used for propulsion (eg, the main engine of the aircraft) and / or for power (eg, the auxiliary power unit (APU)). It should be appreciated, however, that the invention is not limited to use with a particular type of electric machine. Thus, while the invention has been shown and described fo...

Abstract

The invention relates to a terminal assembly with reduced creepage. The terminal assembly (54) includes a terminal board (56) with an interrupted aperture (78) to receive a passthrough (62).

Description

technical field [0001] The present disclosure relates to rotating electrical machines, such as high speed starter generators for gas turbine engines, and more particularly to terminal board assemblies for delivering electrical power thereto. Background technique [0002] Aircraft may include various types of rotating electrical machines, such as generators, electric motors and starter / generators. The starter / generator can be operated as a starter or a generator. [0003] Electrical power from or supplied to the starter-generator may be transferred via one or more terminal assemblies. Each terminal assembly may include a feedthrough coupled to the stator output leads inside the generator housing and to a terminal block assembly outside the generator housing. [0004] Terminal assemblies are designed to provide various clearances such as "arcing" performance, breakdown performance and creepage performance. Creepage distance is usually the shortest path between two conductiv...
