Embodiment Construction

[0046] see Figure 1-3 , is the device of Embodiment 1 of the present invention, denoted by reference numeral 10, and is used to construct an axial motor.

[0047] The device 10 mainly includes two different structures.

[0048] The first structure is a disk or ring 12 (for simplicity, hereinafter referred to as disk), which forms the rotor of the device 10 , mounted on a shaft 13 . The main surface of the disk 12 contains a ring of identical permanent magnets 14 distributed in a regular manner along the circumference of the disk 12, at the outside near the edge of the disk. The magnets 14 are arranged on each surface of the magnetic disk 12 in such a manner as to form successive alternating and opposite magnetic poles. exist Figure 1-3 In the illustrated embodiment, the disk 12, in the areas not covered by the magnets 14, is made of a non-ferromagnetic material.

[0049] The central part of the magnetic disk 12 has a plurality of blades 15, which have a pushing action, c...

Abstract

A modular electromagnetic device (7) has a stator (16, 20a, 20b, 18, 22a, 22b) and a rotor (12) rotating between facing surfaces of the stator (16, 20a, 20b, 18, 22a, 22b) and bearing a plurality of magnets (14) distributed with alternate orientations in a substantially ring-shaped pattern, and the stator (16, 20a, 20b, 18, 22a, 22b) comprises at least one pair of magnetic yokes (16, 18) symmetrically located at both sides of the rotor. Each yoke (16, 18) has a pair of projecting arms extending towards the magnets (14) and bearing a respective coil (20a, 20b, 22a, 22b) for collection of electric power from or supply of electric power to the device (10). Each yoke (16, 18) is individually mounted on an own support equipped with adjusting units arranged to adjust the yoke position relative to the confronting magnets (14), and forms, together with its coils (20a, 20b, 22a, 22b; 20', 22'), its support, the adjusting units thereof, and sensing and control means controlling the yoke adjustment, an elementary stator cell that can be replicated to form single-phase or multiphase modules.

Description

technical field [0001] The present invention relates to an electromagnetic device with reversible generator-motor operation, ie a device that can convert kinetic energy into electrical energy and vice versa. Background technique [0002] In many industrial fields, it is often necessary to install reversible motors in systems containing rotating elements, so that, taking into account the operation of the system in which the motor is installed, or developing such elements to generate electrical energy to supply other system components, or to provide Electrical energy causes the rotating element to rotate. [0003] The basic requirements of these machines are to be simple, flexible and inexpensive, especially when applied to means of transport such as land vehicles or aircraft. [0004] One such machine is disclosed in US 6,832,486. The patent discloses a reversible electric motor used in the aviation field, which is coupled with a turbine of an aircraft engine to generate el...
