Speed Variation of D-C Motors

1996-08-01
CURRENT
AIR857A
The scope of this SAE Aerospace Information Report (AIR) is a review of the factors contributing to speed variation of d-c motors, a presentation of typical data showing speed variation as a function of certain variables for representative motors, and a recommendation of a means of improving communications between motor users and manufacturers. The following analysis is limited to variations in voltage, torque, temperature, and altitude of the same magnitude as in MIL-M-8609.

Penalties in Performance of Three-Phase, Four-Wire, 400-Cycle Motors Causes By the Opening of One Phase

1957-11-01
HISTORICAL
AIR34
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 latidue 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.

HISTORICAL
ARP826
This document covers resolvers which are used to perform coordinate transformations as well as sine and cosine computations, It includes both the categories of compensated and uncompensated resolvers which perform these functions. Linear resolvers are also included because of their similarity to resolvers.

ARP497B
This recommendation establishes objectives for high performance control motors to be used with aeronautical and associated equipment in protective enclosures or completely within the shell of the aircraft so that they are subjected only to the internal climatic conditions of heat, cold, shock, vibration, altitude, and humidity. Control motors larger than size #23 are not covered in this document.
