Patent ID: 11742733

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 both the 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).
