Abstract

PURPOSE: To simplify the assemble by attaching the secondary winding or a coil frame with the winding wound around it to I-shaped magnetic substance.
CONSTITUTION: Four projection pieces 3 are mounted on a magnetic substance 1, two central projection pieces have a double cross section greater than that of the end projection piece and a spacing 3 is formed in assembling the magnetic substance by two magnetic substances 1 and 2. A through-bar used as a primary winding 5 for each phase is passed through the spacings respectively. A secondary winding is wound around the magnetic substance 2 corresponding to the primary winding. In the absence of the phase at the end, the secondary current induced in the lacked phase may be equivalent to one percent of the current flowing through the conductive phase, therefore no influence would be appeared. The secondary current induced by influence of the gap can be selected by interposing the insulated member between the coupling portion of the magnetic substance when it is assembled. According to such the construction, the yoke is integrated with other parts to be formed in a small size and light weight and a wide variety of the machine types having various characteristics can be easily materialized.
