Disclosure of Invention Completely As shown in Illustration 1, Generator and Motor Ventilator 1 is installed on Rotating shaft 2, and Rotating Shaft 2 has six pieces of spokes 3 which are 40 attached with a Ring Frame 4. Four pieces of Metal Plates 5 are used to support an Axial Shaft 6 and are attached with the Ring Frame Structure 7 for installing with a Roofing Set. On the Metal Plate 5 there is installed a Non Metal Case 8 for attachment with Inductance 9 by round and on the spokes 3 there is installed a Case 10 for attachment with magnets 11 all around, by leaving proper 45 space 12 between Inductance 9 and magnets 11. Both the Rotating Shaft 2 and the Axial Shaft 6 are installed at the centre of rotation.
Page 2 of 4 As shown in Illustration 2, the case 10 is attached with twelve pieces of Magnets 11 arranged by in alternating polarity between North magnetic pole and South magnetic pole. As shown in Illustration 3, the Non metal case 8 is attached with nine 5 sets of Inductance 9 in order. As shown in Illustration 4, there is an assembly of the Non metal case 8 for attachment with Inductance 9 as an outer ring, and having the Case 10 for attachment with the magnets 11 as an inner ring. Appropriate space 12 is left between Inductance 9 and Magnet 11 for the assembly to rotate smoothly 0 As shown in Illustration 5, the Ring Frame 4 has six pieces of spokes 3 attached. At the centre of the ring frame 4 the spokes 3 are appended with the Rotating Shaft 2. The spoke 3 are also attached to Case 10 for attachment with twelve pieces of Magnets 11 which are arranged by alternating polarities between North magnetic pole and South magnetic pole by Case 10, and Rotating 5 Shaft 2 is at the centre. As shown in illustration 6, the Ring Frame Structure 7 has four pieces of Metal Plates 5 appended radially from a centre of the ring frame structure 7, and at the centre the Metal plates 5 are attached with an Axial Shaft 6. On the Metal Plates 5 there is a Non Metal Case 8 attached with nine sets of magnet 0 arranging closely and the Non Metal Case 8 is concentric with Axial Shaft 6 Illustration 7 shows an Assembly with the Non Metal Case 8 for attachment with Inductance 9 as an outer ring, and having the Case 10 for attachment with the magnets 11 as an inner ring, by leaving the proper space 12 between Inductance 9 and Magnet 11 around to rotate smoothly and together 5 with Rotating Shaft 2. The illustration 8 shows the Component of Generator and motor ventilator 1 which is composed on the Rotating Shaft 2. Inside the Rotating Shaft 2, there is a Rotation Shaft End 2.1 being installed on a V shape crucible 6.1 which is located on the Axial Shaft 6. On the Spokes 3, there is installed the case 0 10 for attachment with magnet 11s.

As shown in Illustration 9, the rotation of Generator and Motor of Ventilator will generate a 3-phase alternating current. At Inductance 9, the 3 35 phase alternating current is connected through Inductance 13 to Rectifier 14. Then, connect in parallel with Capacitor 15 and to switch 16 by using a metal oxide semiconductor field effect transistor (MOSFET) as a switch to connect with Inductance 17 to battery 18, which is controlled by a Microcontroller 22 which has a Regulator 20 receiving voltage from the battery 18, and allows current rate 40 to flow at 21 to make the circuit work. Then a comparison is made between the voltage of generating electric power set joining into point 23 and the voltage from battery 18 joining into point 25. If the voltage of generating electric power set at point 23 is higher than the voltage from battery 18 at point 25, the microcontroller 22 will command gate set 26 to close switch 16 (open-close 45 circuit by using MOSFET) to close the circuit, for making Natural Roof Ventilator work as a generator and charging into the battery 18. When charging occurs, the voltages at capacitor 15 will be lowered, and then the Switch 16 (open-close circuit by using MOSFET) will open circuit. The capacitor 15 will recharge for increasing more power energy.

When the voltage from generating electric power is lower or as zero comparing to voltage from battery 18 at point 5 25, the Generator and Motor of Ventilator does not rotate, and Microcontroller will process data for Gate Drive 27 to command switch 28 to close circuit by using MOSFET as switch to allow electric current from battery 18 to flow through Inductance 17 completely, making magnetic field at Inductance 17 occurred in a short period. And then switch 28 opens circuits by using MOSFET as a switch to o make Back emf. At Inductance 17, positive voltage together with voltage from battery 18 flow through Diode 29 of Switch 29 (open-close circuit by using MOSFET as a switch) to switch 31 to close circuit by using MOSFET as a alternately switch in converter type flow through Inductance 13 to Inductance 9, making Generator and Motor Ventilator 1 functions as motor whether rotating in 5 the right direction or not. If rotate in the right direction, it will command switch 31 to close circuit by using MOSFET as a switch to allow electric current flow from the battery 18 to Inductance 9 for making Generator and Motor Ventilator 1 work as motor on and on. If wind speed makes Generator and Motor Ventilator 1 have higher voltage of generating electric power set than voltage from battery 0 18 at point 25, the Microcontroller 22 will command the switch 31 to open circuit by using MOSFET as a switch. At point 26 the Microcontroller 22 will command switch 16 to close circuit by using MOSFET as a switch to close the circuit for charging electric current into the battery 18 6.
