Scope
The scope of this SAE Aerospace Information Report (AIR) is to present a guide for the determination of probable power output and the effect on the aircraft system that will be experienced when operating three-phase motors with one phase open. Unfortunately, the above subject cannot be resolved by specific rules. Modern aircraft or missile electrical systems are composed of a wide variety of electrical and electronic components. These components react differently under identical impetus due to the latitude of their design. This latitude of design must be allowed wherever possible to the accessory designer due to the various specification requirements.
Therefore, it cannot be over-emphasized that the effect on the airplane or missile system, as well as motor operation, of three-phase motors on two-phase power must be thoroughly investigated.
Rationale
This document has been determined to contain basic and stable technology which is not dynamic in nature.

Issuing Committee
AE-7A Generators and Controls Motors and Magnetic Devices
The scope of the AE-7 Aerospace Electrical Power and Equipment Committee is dedicated to developing standards and specifications relative to the generation and control, storage, conversion, distribution, load management and utilization of electric power for aerospace vehicles. The Committee also provides a forum for gathering and disseminating electrical power and technical equipment information between users and suppliers.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
