Lmc. Mhango et R. Perryman, ANALYSIS AND SIMULATION OF A HIGH-SPEED 2-PHASE AC DRIVE FOR AEROSPACE APPLICATIONS, IEE proceedings. Electric power applications, 144(2), 1997, pp. 149-157
The majority of aerospace high-speed AC drives are high energy density
electric motors that employ small diameter and long axial length. The
se motors are supplied from a three-phase, 400 Hz aircraft supply. The
ir construction is either a two-pole or a four-pole design using a thr
ee-phase stator winding. The paper suggests an alternative drive based
on a novel form of two-phase inverter-fed induction motor with magnet
ic bearings providing the rotor support. The paper develops theoretica
l equations which model the performance of the two-phase drive and ill
ustrates how the performance can be simulated using numerical methods.
A comparison of simulated and experimental results is presented which
demonstrates excellent correlation. The benefits of using the two-pha
se drive for aerospace high-speed applications are discussed and the a
dded advantages of using magnetic bearings are also presented. Since e
lectromagnetic compatibility (EMC) is an important requirement for aer
ospace drives the results achieved for the two-phase drive substantiat
e its suitability in this application area.
