ABSTRACT:
An iron core including two outer legs and a central leg connected at each end to a different one of the outer legs through a yoke. Each of the outer legs includes a stack of trapezoid laminations connected to a stack of trapezoid laminations of the yoke alternating its trapezium laminations through angle butt joints arranged stepwise with equal incremental intervals, the yoke laminations being longer than one another by equal increments equal to that intervals. The central leg includes a stack of parallelogramic laminations alternating those inverted widthwise from the same and connected in lapped relationships to the yoke laminations.
