Permanent magnet electric machine with energy saving control

Abstract

The present invention relates to a generator of energy as a dynamo-electric machine with employment of the parallel and superposed forces, of ''artificial electromagnetic reaction'' between the primary (2) and secondary (3) of ''natural ferromagnetic reaction'' between the secondary and the primary. The primary comprises one or more pairs (C1, C2) of polar expansions (E1, E2; E3, E4), mechanically separated and electrically offset in phase from each other by a polar step (p) and each provided with a ferromagnetic core (A1, A2; A3, A4) and with at least an electromagnetic coil (B1, B1', B2, B2', B3, B3', B4, B4'), the secondary (3) comprises a succession of alternate permanent magnets (31, 32, . . . , 310), and a related control system (5). Each polar step (p) spans half a permanent magnet of said alternate permanent magnets (31, 32, . . . 310), equal to a quarter of a complete cycle (p1 or p2), the magnetic forces being balanced due to the characteristic paired disposition of the polar expansions active separately during the conductor steps (p1) and its ferromagnetic cores active separately during the neutral steps in ''natural'' attraction (p2) with the permanent magnets.

Description

technical field [0001] The invention relates to an energy generator as a motor with independent use of interaction force and balance of interaction force with permanent magnets. [0002] The term "electrical machine" means any machine capable of converting mechanical energy into electrical energy, and vice versa. A motor of the type to which the invention relates is one in which the primary side comprises a number of polar expansions and the secondary side comprises a series of permanent magnets arranged alternately of opposite sex. Background technique [0003] It is well known that in motors and generators of this type, electromagnetism interacts by attraction and repulsion over the two half cycles, that is to say over the entire pitch of the magnets from the permanent magnets to the full circumference of the permanent magnets, Thus neither the positive effect of the magnet interaction with a ferromagnetic core of high permeability nor the balance, i.e. the balance of the...
