PURPOSE:To eliminate a magnetic saturation on the back surface of a magnetic flux shunt by notching an outside spacer at a core outer peripheral side, and filling a magnetic flux shunt laminated steel plates therein. CONSTITUTION:A core 1 made of laminated steel plates is clamped by a toothed portion by an outer spacer 2. A magnetic flux shunt 3 made of the laminated steel plate is provided at the axial outside of the spacer 2. They are tightly clamped by another spacer 4 and a core retainer 5. In this case, the outer periphery of the spacer 2 is notched at a radially at b axially, and the shunt 3 made of the laminated steel plates is also filled therein. Thus, a magnetic flux saturation can be eliminated on the back surface of the shunt to reduce the core end temperature rise. |
