Title:
LIGHT-WEIGHT ALTERNATING-CURRENT CONTACTOR IRON CORE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/180632
Kind Code:
A1
Abstract:
A light-weight alternating-current contactor iron core. The iron core is formed by stacking silicon steel sheets, and a hollow structure (1) is arranged on each silicon steel sheet, so as to reduce the weight of the iron core. By conducting light-weight processing on the iron core, the weight of an alternating-current contactor device is reduced, thereby further improving the operating efficiency and reliability of an alternating-current contactor. The actual weight reduction effect can reach or even exceed 17%, and for a high-power contactor, the weight reduction effect is outstanding. By selecting a hollow position reasonably, the influence on the structural strength of the iron core can be reduced, and the influence of the hollow structure on the magnetic conductivity of the iron core can be compensated by adjusting parameters of a drive system, etc., so that the normal use of the iron core may not be affected. The alternating-current contactor iron core is suitable to be used in space equipment, aerospace equipment, naval ships, vehicles, etc.
