초록

An electrical starter-generator system includes a first starter-generator and a second starter-generator. A single drive controls both the first starter-generator and the second starter-generator such that their electrical current and power inputs are minimized and balanced.

청구항

We claim: 1. A method of controlling an electric starter-generator system, comprising: (a) mechanically aligning a first rotor of a first starter-generator relative to a second rotor of a second starter-generator; and (b) controlling a first electro-motive force in the first starter-generator to be approximately in phase with a second electro-motive force in the second starter-generator. 2. The method as recited in claim 1, wherein said step (a) includes mechanically aligning a first orientation of a first rotor field winding of the first rotor relat...
