THE SINGLE-INDUCTOR LINEAR MOTOR CHARACTERISTICS AND APPLICATIONS

LE MOTEUR LINEAIRE A UN INDUCTEUR. CARACTERISTIQUES ET APPLICATIONS

By application to a given motor (mechanical rating 74 kW, nominal speed 15 m/s; 8 poles, 50 cycles; length 1600 mm, width 200 mm, thickness 95 mm; air gap 5 mm; width of armature 200 mm, thickness 3 mm, aluminium; solid yoke; linked to armature; 18 mm thick), complete calculation methods are developed in the article, based on the solution of Maxwell equations in the various areas concerning air gap and armature and, with the use of graphs, the authors demonstrate how parameters such as the influence of end and side effects, the resistivity and thickness of the armature, the air gap and the type of magnetic yoke, have an influence on thrust, output, the power factor and the motor utilization coefficient. The authors then propose several solutions for perfecting the motor, and conclude with considerations on possible applications in the context of electric traction and mechanical handling.
