Electric machine with multiple air gaps and a 3D magnetic flux

An electric machine with multiple air gaps and a 3D magnetic flux, including:

• an axis of rotation;
• a stator equipped with an armature and at least one annular exciter unit that includes a coil, a first annular yoke, and a second annular yoke, with the coil being positioned inside the first and second yokes and having at least two faces, each respective yoke of the first and second yokes including a respective plurality of teeth;
• and
• a rotor revolving around the axis of rotation and equipped with a structure and at least one annular receiver unit, with each respective receiver unit of the at least one receiver unit including a plurality of magnets and cooperating with a single respective exciter unit of the at least one exciter unit, with each magnet having a magnet north pole and a magnet south pole, with one of the magnet north pole and the magnet south pole being located opposite the respective exciter unit and with the other of the magnet north pole and the magnet south pole being located opposite the structure of the rotor, with the total number of magnets being equal to the total number of the teeth;
• wherein each respective yoke includes at least two respective extreme sides, the respective plurality of teeth of each respective yoke being distributed angularly along the two respective extreme sides in a regular manner about the axis of rotation, the respective pluralities of teeth of the first and second yokes being fitted into each other on one of the faces while maintaining a distance therebetween, alternately forming tooth north poles and tooth south poles, with each respective receiver unit of the at least one receiver unit including at least two rows of respective magnets of the plurality of magnets, with the at least two rows of magnets of each receiver unit being linked for rotation together, with each row including an alternation of magnet north poles and of magnet south poles, and being located facing one of the faces, with the magnets being distributed angularly in a regular manner about the axis of rotation, thus forming an air gap between each row of magnets and the respective exciter unit, with a magnetic flux thus circulating in three dimensions inside the electric machine, wherein a respective exciter unit of the at least one exciter unit cooperates with a respective receiver unit of the at least one receiver unit that includes two respective rows of magnets, with two air gaps thus being formed between the respective exciter unit and the respective receiver unit.
