Due to the reliability problems of mechanical position sensors, rotor position estimation
technology is an alternative for the starting control of aircraft wound-field synchronous …

For an aviation brushless synchronous starter/generator system, rotors of the main exciter
(ME) and main machine (MM) rotate synchronously. Meanwhile, abundant current harmonic …

Using the main exciter (ME) as the quasi-resolver is an emerging advanced sensorless
control technology. Since the ME becomes a dual-use machine, the structure of a brushless …

A three-phase interior permanent magnet (IPM) machine with 18-stator-slots/12-rotor-poles
and concentrated armature winding is commercially employed as a 10 kW integrated-starter …

Cracks in rotor systems are generated because of internal as well as external heavy loading
conditions. The external loading conditions could be attributed to thermal gradients (such as …

The estimated field current (EFC) of the main generator (MG) contains information related to
the rotor position of the main exciter (ME). Besides, MG and ME are mounted on the same …

This paper focuses on torque maximization of electrically excited (EE) machines considering
variable stator/rotor copper loss ratio (SRCLR) in design optimization. Firstly, two EE …

Fault diagnosis of the rotating rectifier in Brushless Wound-Rotor Synchronous Starter-
Generator (BWRSSG) plays an important role for improving the reliability of the aircraft …

The cross-coupling effect is the most common phenomenon in the electric machinery
operation. It has the influence on the machine efficiency and control scheme. However, the …

The wound-rotor synchronous machine has become a competitive candidate for the
integrated starter–generator of more electric aircraft. Due to the large inertia of aircraft …
