To create an electric motor, comprising a rotor and a stator, whereby the rotor is spherically supported, which motor has a high efficiency, it is proposed, that the rotor produces a magnetic field, that the surface of the rotor facing the stator has a spherical configuration, that the rotor and stator are adapted to each other so that a maximal magnetic attraction force which keeps the rotor on the spherical bearing is larger than the maximal axial counterforce.

Electric motor with circulator pump

A centrifugal pump with an integrally-constructed electrical motor. The motor has a hemi-spherical rotor mounting the impeller and comprising at least two permanent magnetic poles. The rotor is balanced on a spherical bearing including a ball or a hemispherical structure mounted at the end of a shaft engaged into an axial cavity in the smallest end of the rotor. A thin, waterproof and static septum is positioned in the air gap between the stator and the rotor. The annular stator includes a bowl-shaped yoke and a winding, applied to the inner surface of the yoke, comprising segments running in successive alternate sections obliquely to the motor's axis of rotation between the upper and lower rims of the yoke. Due to the geometry of the motor, the residual magnetic forces urge the rotor toward a balanced position against the shaft and bearing.

Centrifugal pump with integrated motor

A compact electrical motor, particularly adapted to act as the driving component of a centrifugal pump, has a hemispherical rotor mounting the impeller and comprising at least two permanent magnetic poles. A thin, waterproof and static septum intimately surrounds the rotor. A circular stator includes a bowl-shaped yoke and a winding applied to the inner surface of the yoke and comprising segments running in successive, alternate sections obliquely to the motor's axis of rotation between the upper and lower rim of the yoke. The successive foldings of the strands about the upper and lower rim of the yoke substantially eliminates the electro-mechanically inactive and power-dissipating portions of the stator or winding found in motors of the prior art.
