Abstract
The utility model discloses a variable inductance magnetic core, include: first magnetic core, it is sleeve -shaped arrangement, and the inner wall perimeter circle of first magnetic core has a plurality of first V type groove along the length direction of first magnetic core setting, second magnetic core, it is cylinder -shaped arrangement, and the outer surface perimeter circle of second magnetic core has a plurality of second V type groove along the length direction of second magnetic core setting, the second magnetic core is embedded in first magnetic core, and there is a gap between first magnetic core and second magnetic core, and the fixed structure for fixing the relative position between first magnetic core and second magnetic core is equipped in the gap. The scheme is through the nesting design of first magnetic core and second magnetic core, and combines V type groove design, realizes the wide range adjustment of inductance and the optimization of magnetic circuit.
