Abstract

During the last three decades, the design effort is being concentrated on realization of more all-electric aircraft concept. We can assign to this class the planes incorporating, either power hydraulic or pneumatic actuators for energy-intensive installations control, or electric motor drives controlling various functional objects, such as steering rudders. Nowadays the research effort is focused on two types of drives design — electromechanical and electric hydrostatic drives. The electromagnetic interference (EMI) generated herewith by electric drive motors in the form of electromagnetic fields may affect the operation of aircraft on-board equipment which, in some cases, causes failures. Furthermore, electric drive modules represent receptors of external radiated and conducted interference, which may distort control signals, formed by microcontroller and, hence, conducted EMI in motor windings in the form of phase currents transients. Thus, it is necessary to know the levels of motor phase currents, occurring during various transients, to provide normal operation of the dive and evaluate electromagnetic environment within the aircraft interior.

The goal of the paper consists in the analysis of the phase currents transients occurring in the steering drive system (SDS) motor, based on the results obtained by computer simulation in OrCad 9.2.

The paper presents waveforms of phase currents in motor windings, obtained with OrCAD simulation. The phase currents levels in actuating motor windings may be about 1.5 times greater than their rated values while operating mode variation. The above said currents and the EMI they induced in the form of electromagnetic fields affect the electromagnetic environment within the interior volume and are of serious hazard to electronic equipment of either SDS, or to aircraft on-board equipment.

The presented paper is a part of research on calculation and simulation of electromagnetic interference caused by the transients in current amplifier of an aircraft SDS motor.
