Abstract

An electrical machine with two or more stators is proposed. One stator (1) is stationary and is fixed to the body (4) of the machine, and the second stator (6) is movable and can rotate freely to boththe rotor (2) and the stationary stator (1). The movable stator (6) is self-orienting according to the lines of the magnetic field created by the electric windings and / or permanent magnets of the stationary stator (1). The movable stator (6) concentrates and shapes up the magnetic field B so that the magnetic lines are almost perpendicular to the rotor windings. The movable stator (6) does not rotate relative to the magnetic field of the stationary stator (1) and the magnetic field in it does not change, there is no continuous re-magnetization, magnetic hysteresis is avoided and no eddy currents are generated, due to which the losses and heating of the machine are reduced. The movable stator (6) may comprise permanent magnets to increase the magnetic field in the rotor active zones (2).

Description

technical field

[0001] The present invention generally relates to electrical machines designed to convert mechanical energy to electrical energy and vice versa by using electromagnetic induction. More specifically, the invention relates to a method of directing a magnetic field by adding an auxiliary self-directing element called a movable stator to the stator and rotor of a machine. Background technique

[0002] Each rotating electric machine has a stator and a rotor separated by a gap. The main part of an electric machine produced in motor mode at the time this patent application was filed uses a magnetic field to transfer energy between a stator and a rotor and transform electrical energy into mechanical motion. In generator mode, inverse commutation occurs - the magnetic field creates a current in the windings. In all electric machines, the direction of energy conversion can be changed, i.e. they can convert mechanical energy into electrical energy (generator mode) or ...
