Abstract
A magnetic circuit (1) with coil having an electric coil (2) and a magnetic core (3), the coil (2) comprising a conducting wire (6) and an end plate (4) and connector (5) being arranged at respective ends of the coil (2). The coil is mounted on the magnetic core (3) which is formed of a tore-shaped magnetic wire.
Claims12
A method of making a magnetic circuit with coil (1) having a electrical coil (2) and a magnetic core (3) comprises the steps of making a coil (2) by winding a conducting wire (6) on a mandrel (12) having a slightly conical exterior surface (14), inserting the coil (2) on the magnetic core (3) in the form of an open spire having ends (16, 16′), said spire being formed before providing the magnetic material of the spire with specified magnetic properties and deforming the ends (16, 16′) of the magnetic core in a substantially orthogonal direction (O) to the plane of the magnetic circuit with coil in order to move them closer together.
A magnetic circuit (1) with coil comprising an electrical coil (2) and a magnetic core (3), the coil (2) comprising a conducting wire (6), an end plate (4) and a connector (5), each being arranged at respective ends of the coil (2), the coil being mounted on the magnetic core (3) formed of a tore-shaped magnetic wire.
A device for making a magnetic circuit with coil comprising a coil (2) mounted on a tore-shaped magnetic core (3), the device comprising a mandrel (12) around which the coil is wound, the mandrel comprising an outer surface (14) having a slightly conical shape.
