The invention relates to a power generating device comprising a plurality of rotors, magnetic conductors and stators, which are arranged in a certain order.

A vehicle wheel is often equipped with a power generation system that includes a generator. The generator can convert the mechanical energy of the vehicle into electrical energy that can be supplied to the vehicle's power consumers.

From the Taiwanese patent M440593 For example, a power generation apparatus is known which has a main body, an axle rod and a power generation unit. The power generation unit includes rotors and stators, which are alternately ranked. The rotors each carry a plurality of neodymium magnets and are fixed to the main body. The stators carry coils and are attached to the wheel axle. When the main body is rotated, the rotors are rotated with respect to the stators, thereby shielding the field lines, thus inducing a current.

• 1. Die Neodym-Magnete können zwar eine hohe elektromagnetische Kraft und somit einen hohen Strom erzeugen, es werden jedoch die Kosten durch die Neodym-Magnete erhöht.
• 2. Wenn die Gebrauchsmenge der Neodym-Magnete reduziert wird, ist die erzeugte elektromagnetische Kraft bei der Anwendung auf ein Fahrzeugrad niedrig.

However, this power generation device has the following disadvantages:

The magnetic conductors are each formed by an iron plate.

When N = 1, the power generation unit includes a rotor, two magnetic conductors and two stators, which are arranged in order of a magnetic conductor, a stator, a rotor, a stator and a magnetic conductor.

The stator has holes in which the coils are arranged, and the number of neodymium magnets of the rotor is 28.

The neodymium magnets are trapezoidal. The axle rod is hollow and an electrical line is passed through the axle rod.

The main body is a wheel rim and the axle rod is a wheel axle. The main body has a bottom and an annular wall, wherein the bottom and the annular wall form a receiving space in which the power generating unit is arranged.

The outermost magnetic conductor in the receiving space has an outer flange which lies on the base body and closes the receiving space.

• 1. Im Vergleich mit der herkömmlichen Lösung werden mehr als die Hälfte der Rotoren von den Magnetleitern ersetzt, wodurch die Materialkosten reduziert werden.
• 2. Mehr als die Hälfte der Rotoren werden von den Magnetleitern ersetzt, wodurch die Feldlinien zwischen den Neodym-Magneten und den Magnetleitern dichter sind. Die Magnetleiter können teilweise die Funktion der Neodym-Magnete der Rotoren übernehmen. Die gemäß der Erfindung erzeugte elektromagnetische Kraft ist im Vergleich mit der herkömmlichen Lösung zwar niedriger, es wird jedoch die Gebrauchsmenge der Neodym-Magnete um mehr als die Hälfte reduziert, so dass die Materialkosten der erfindungsgemäßen Stromerzeugungsvorrichtung erheblich reduziert werden.
• 3. Der äußerste Magnetleiter kann als Deckel verwendet werden und den Aufnahmeraum verschließen, um die Stromerzeugungseinheit zu schützen.

The number of neodymium magnets ( 311 ) of each rotor ( 31 ) and the number of coils of each stator ( 33 ) have the following relationship: N = T · 2m / P, where N is the number of neodymium magnets ( 311 ) of each rotor ( 31 ), T for the number of coils ( 331 ) of each stator ( 33 ), P stands for the phase number of the induced current and m for the factor of Fildlinienabschirmung. In the present embodiment, each stator carries ( 33 ) 21 coils ( 331 ). The induced current is three-phase, ie P = 3. The factor of the field line shield m = 2. This results in the number of 28 of the neodymium magnet ( 311 ) of each rotor ( 31 ).

This causes the field lines between the neodymium magnets ( 31 ) and the magnetic conductors more dense. The magnetic conductors ( 32 ) can partially take over the function of the neodymium magnets of the rotors. Although the electromagnetic force generated according to the invention is lower in comparison with the conventional solution, the use amount of the neodymium magnets is reduced by more than half, so that the material cost is significantly reduced in the embodiment of the present invention.
