Description

The invention relates to the field of contactless electric machines and can be used as a synchronous generator, direct current generator with static rectifier, synchronous and asynchronous contactless motors, alternating and direct current engines with static KOMMyTaTQpaMH and in other modes.

An electric machine is known that contains, as well as axially mixed, closed and jagged radial magnetic cores, closed by the corresponding axial magnetic cores, and fixed annular field windings and a core located between said magnetic cores.

A disadvantage of the known machine is the low use of active materials and the limited scope of its use, since the machine can only be made single phase.

The purpose of the invention is to eliminate the indicated disadvantages.

For this purpose, toothed magnetic cores are located between two closing magnetic cores, the excitation windings and the core windings are alternately arranged in the axial direction, with one of the windings between two adjacent magnetic cores. In addition, in order to improve the switching of the magnetic flux and, consequently, increase the use of active materials, the magnetic circuit is made jagged.

FIG. 1 shows a single-phase machine in longitudinal section; in fig. 2 - electric machine (multi-package version).

The inductor electric machine contains a stator 1 and ipOTOp 2. The rotor consists of a shaft

3, on which the sleeve 4 is mounted with an axial magnetic core 5, a closing 6 and a gear 7 radial magnetic cores of the rotor. The stator of an electric machine consists of a housing 8, in which an axial magnetic core 9 is placed, the closing 10 and toothed 11 radial magnetic cores, the excitation windings and the core windings. The excitation windings are included in the opposite direction, and the toothed magnetic cores of the rotor or stator with a single-phase execution of the machine are shifted but the circumference of the bore by half the gear division.

Closing the magnetic circuit 6, 10 can be made both smooth and serrated.

To increase the power with a limited diameter single-phase machine, it is advisable to perform a multi-packet, formed by an alternate set of annular magnetic conductors, excitation windings and the core within

shaft length, determined by its strength (Fig. 2).

A multi-phase machine can also be made multi-pack, with the radial toothed magnetic cores being additionally shifted in pairs with respect to the positions indicated above for single-phase

machines, on the tooth division, where / C-

l-yes

integer, t - the number of phases of the machine.

When the rotor rotates, the flows created by the excitation windings alternately penetrate the windings of the core in the axial direction, leading to emf. Phase emf in the windings of the core of a multiphase machine is proportional to the additional shift of the toothed magnetic cores.

The increase in the use of active materials in a machine is promoted by a change in the magnetic flux in magnitude and direction, as well as its multiphase performance. In a multi-pole machine, this is facilitated by the concentration of the windings.
