Abstract

A portable handheld electrical power generator for general consumption by household electronic devices is disclosed. The portable handheld power generator provides a magnet reinforcing ring and an armature core of stator lamination stamped with insulation film to provide improved performance and longer lasting operational life. The generator includes a generator casing; a cranking system, a set of cranking gears and an alternator comprised of a magnet-rotor base, a magnet reinforcing ring, a plurality of magnets, induction coils, armature core of stator lamination stamped with insulation film, all in a concentric manner and centered around an alternator drive shaft and housed within the generator casing. When a user manually drives the cranking handle, it causes the gear set to rotate which, in turn, brings about corresponding caming of the induction coils and the armature core, thereby generating electrical power for consumption.

Claims

1. A portable handheld power generator for generating electrical power comprising,

(a) a generator casing;

(b) gear means housed within said generator casing;

(c) cranking means mounted on said generator casing and operatively connected to said gear means;

(d) an alternator comprised of a magnet-rotor base, a magnet reinforcing ring, a plurality of magnets, induction coils, armature core of stator lamination stamped with insulation film, all in a concentric manner and centred around an alternator drive shaft and housed within said generator casing and operatively positioned about the gear means for generating electrical power in response to rotating movement of said gear means caused by driving said cranking means; and

(e) electrical output connector means for channeling electrical power generated by said alternator for general power consumption.

2. The portable handheld power generator of claim 1, wherein said gear means is comprised of a primary gear and one or more secondary gear, whereby the rotating movement of the cranking means causes the primary gear to increase the gear ratio of the secondary gear to drive up the rotating speed of said alternator.

3. The portable handheld power generator of claim 1, wherein said insulation film is made of plastic or polyethylene.

4. The portable handheld power generator of claim 1, wherein said magnet reinforcing ring is made of metal.

5. The portable handheld power generator of claim 1, wherein said electrical output connector means is comprised of three-pin wires connected by a 3PC connecting pin or cord.

6. A method for generating electrical power comprising:

(a) driving a cranking means mounted to a portable handheld power generator casing, said cranking means is operatively connected to a gear means housed within said generator casing;

(b) rotating said gear means thereby causing an alternator to cam around an alternator shaft, said alternator being housed within said generator casing and operatively positioned about said gear means and comprising a magnet-rotor base, a magnet reinforcing ring, a plurality of magnets, induction coils, armature core of stator lamination stamped with insulation film, all in a concentric manner and centred around said alternator drive shaft; and

(c) channeling electrical power generated by said alternator to an electrical output connector means for general power consumption.

7. The method of claim 6, wherein said gear means is comprised of a primary gear and one or more secondary gear, whereby the rotating movement of the cranking means causes the primary gear to increase the gear ratio of the secondary gear to drive up the rotating speed of said alternator.

8. The method of claim 6, wherein said insulation film is made of plastic or polyethylene.

9. The method of claim 6, wherein said magnet reinforcing ring is made of metal.

10. The method of claim 6, wherein said electrical output connector means is comprised of three-pin wires connected by a 3PC connecting pin or cord.
