Abstract

The invention relates to electrical engineering, in particular, to devices that provide for the creation of magnetic fields of a given configuration during magnetization of permanent magnets. The aim of the invention is to provide the possibility of simultaneous magnetization along with the radial direction of axial magnetisation of one of the ends of a cylindrical or ring magnet. The goal is achieved by the fact that in an inductor for magnetization containing coils with flat edges 3 formed by curved plates of a material with high electrical conductivity, the sides of the coils form between them the dihedral angles corresponding to the corners of the sector zones of the magnetizable magnet 2, pin-conductors 4 provide the opposite direction of the currents in adjacent sides and are formed by the free ends of one of the end sides of each turn, the end faces of the 5 turns not connected to the leads 4, from they are attached to the axis of the cylinder and form contours corresponding to the shape of the axial poles of the magnet 2. 1 Il.

The invention relates to the field of electrical engineering, in particular, to devices ensuring the creation of magnetic fields of a given configuration — days when permanently magnetized — and is an improvement of the known device according to the autor. No. 907594 ..

The aim of the invention is to enable simultaneous multipolar magnetization of one of. the bases of the cylindrical magnet in the axial direction,

The figure shows schematically an inductor for a four-pole magnetisation of a shichdric permanent magnet in the radial direction and one of its bases in the axial direction.

The inductor contains separate coils 1, which are located around the side surface of the magnetized magnet 2. The sides of the 3 coils form between themselves the corners corresponding to the angles of the sectors of the magnetized magnet. The leads-current leads 4 are formed by the free ends of one of the face sides 5 of each turn.

The end sides of the 5 turns, which are not connected with the leads, are bent to the axis of the cylinder and form contours, respectively. shape axial poles.

The inductor works as follows.

A magnetisable magnet 2 of a magnetically hard material in the form of a cylinder or ring is introduced into the space between the turns, which is the

induction zone. From the source through the current leads 4, the current flows through the inductor so that there is an opposite direction in the adjacent lateral sides. In this case, the lateral sides of the 3 turns determine the radial in the working zone of the inductor, and the end sides 5 - the axial magnetic field alternating with polarity. The magnet sample is magnetized in the radial direction, and one of its bases in the axial direction.

The proposed solution allows to provide multipolar magnetization of a cylindrical magnet in the radial direction, and one of its bases - in the axial direction in one operation, which allows to increase labor productivity during magnetization at least 2 times, and also leads to electrical energy savings and the possibility of fewer units of magnetizing equipment.
