DC GENERATOR : 

Materials : 

1. VIMUN SC-3012-2A, 29.44mm×11.6mm×1.1mm, 4 cells + voltage rectifier (inside a solar powered flapping toy) 

2. neodymium sphere 19 mm diameter

(Material NdFeB Shape Sphere Diameter 19 mm Tolerance +/- 0,1 mm Coating Chrome-plated (Ni-Cu-Ni-Cr) Manufacturing method sintered Magnetisation N38 Strength approx. 4,9 kg (approx. 48,1 N) Max. working temperature 80°C Weight 27,2943 g Curie temperature 310 °C Residual magnetism Br 12200-12600 G, 1.22-1.26 T Coercive field strength bHc 10.8-11.5 kOe, 860-915 kA/m Coercive field strength iHc ≥12 kOe, ≥955 kA/m Energy product (BxH)max 36-38 MGOe, 287-303 kJ/m³ 19 mm Pollutant-free according to RoHS Directive 2011/65/EU.)

3. iron head ( MAGNETIC HEX HEAD SCREWDRIVER )

4. plastic holder

5. glue

6. wires

7. two coils iron less with thin wire (one coilwith thin wire from an old ring bell and the second one ("caption coil " inside the microwave syncronous motor turntable 230 V)

8. led ( inside a printer scanner light ) or a normal led

9. two metal cases with holes ( 2 X Neodymium Pot Magnet with Screw Thread )

10. two screws

11. multimeter ( to identify the polarity - DC voltage for the conection between the led and the rectifier (AC to DC)

12. AC to DC rectifier - inside old phone charger ( Important : if you will not use the rectifier you will obtain AC voltage, and the led blinking)

Operations :

1. remove the coil with thin copper wire from the old ring bell.

2. remove the electrical circuit from the powered flapping toy and replace the original air core ( coil ) with the old bell ring coil.

3.remove the neodymium magnets and the original screws from the pot ( refering at2 X Neodymium Pot Magnet with Screw Thread ) , you will obtain two metal cases with holes in the middle.

4. insert the new screws in the metal cases ( the small one and the long one ) and fix them ( you can use a piece of rubber from a conductor/wire).

5.fix the metal cases with screws (magnetic catch) on the neodymium sphere 19 mm diameter

Important fix them on the magnetic poles ( N and S ) for mmaximum high speed motor and align the metal cases for a suitable rotation of the sphere (eliminating oscilations as much as possible)

6. build the plastic holder and fix the sphere (with the long screw up ) by gluing the iron head

Important : there is no friction between the long screw and the MAGNETIC HEX HEAD SCREWDRIVER (iron head) - the long screw placed on the sphere is not touching the iron head !- see the second movie published in this section ( low consumption electric motor test 2 )

Use glass surface - small screw contact !!

7. place the coil (connected to the electronic circuit ) close to the spnere. The sphere will start oscilate and after will start spinning.

BUILD THE DC GENERATOR :

1. remove the led from the printer scanner light

2. place wires on pin 1 and 4 (refering to the led) you will obtain green light.

3. remove the rectifier (AC to DC) from the old charger

4. remove the coil iron-les from the syncronous motor 230 v (microwave turntable motor )

5. connect the coil iron - less through wires to the voltage rectifier "IN " - no polarity

6. identify the polarity of the rectifier ( "OUT" ) and the led (refering to + and -) using a multimeter on voltage scale.

7. connect the led to the rectifier output respecting the polarity ( +and -)

results : Dc voltage

8. THE GENERATOR IS READY aproach the coil as much as possible to the spinning sphere without touch it!
