FIELD OF INVENTION:

The present invention relates to a motor cum alternator system that can power the electrical appliance and can rotate the rotatable object.

BACKGROUND OF THE INVENTION:

The electricity generation is very essential and important task in today’s world. Almost each house and commercial premise need daily electricity. The farmers and industry both need electricity for agro and industrial productions.

Increased coal, oil and gas consumption and depleting natural resources is a serious concern across the globe. Burning of fossil fuels leading to high pollution and the ecosystem is in danger.

Recently the Asian and European countries faced the coal shortage for producing sufficient electricity hampering their industrial functions and affecting their economic growth Even the agricultural and home appliances were shut down due to nonproduction of electricity to adequate extent.

Nowadays the electric vehicles are preferred to minimize the pollution created by the vehicles running on fossil fuels. The electrical vehicles need to be recharged frequently and many countries generate electricity by burning coal or other fossil fuels. Therefore, the pollution control always remains a big challenge. Considering this serious problem, there is need for a cheaper and reliable source of electricity which can be used in variety of applications.

The current invention provides such a motor cum alternator system that can power the electrical appliance and can rotate the rotatable object. The system reduce dependency on the natural resources and also provide the clean environment. SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

Present invention provides a novel, simple, economic, ecofriendly, industrially applicable and efficient rechargeable motor cum alternator system.

Referring to the Figures 2 to 4 the system is explained below. The motor cum alternator system (786) mainly comprises a) a circular nylon stator (7) having slots (9) separated by alternate poles (8); holding a primary copper winding (10a) getting electrical input and secondary copper winding (10b) giving electrical output; and covered by nylon stamping, b) a nylon rotor (11) passing through the circumference of said circular nylon stator (7); having magnetic poles (12); and each of said magnetic pole holds neodymium magnets in vicinity of said primary copper winding (10a) in said nylon stator (7) having polarity opposite to the polarity of neodymium magnets held by its preceding and succeeding pole, c) two nylon end covers (15a, 15b) holding said nylon stator (7) within them; fixed with the bearings (16a, 16b) allowing the shaft (20) of said nylon rotor (11) to pass through them and rotate around its axis, d) a rechargeable battery (2) to provide electrical input to said primary copper winding (10a) through a DC to AC controller (3), a starter key (4) and e) rectifier and capacitor (14) to receive the electrical output from said secondary copper winding (10b) and provide the current through a cutoff switch (17) to said rechargeable battery (2).

Referring to Figure 10, on starting the system with the help of starter key (4) the DC to AC controller (3) convert the direct current from the rechargeable battery (2) to alternating current and supply it to the electrical appliance (1) and to the motor cum alternator. More specifically the current is supplied to the primary copper winding (10a) of the circular nylon stator (7). The alternating current supplied to the primary copper winding (10a) can be controlled through a voltage controller (5). The electrical energy generated due to the rotation of nylon rotor (11) is stored in the rectifier and capacitor (14) and provided to the rechargeable battery (2) its recharge. The cutoff switch (17) disconnects the electrical supply to the rechargeable battery (2) to avoid the overcharging.

In one preferred embodiment, said shaft (20) of nylon rotor (11) is put in contact with the rotatable object. Such a rotatable object may be a shaft of a vehicle axle system Thus, a vehicle can be run through the motor. Said DC to AC controller (3) provide the alternating current to an electrical appliance (1) and said primary copper winding (10a).

In one preferred embodiment, said electrical appliance (1) is selected from an inverter and a motor. The alternating current provided by said DC to AC controller (3) to said primary copper winding (10a) may be controlled through a voltage controller (5).

In one embodiment, said electrical appliance (1) is the inverter supplying electricity to household or commercial purpose electrical equipments. This can provide the electrical energy in the home and industry. The shaft (20) of the nylon rotor (11) can be used as the shaft of motor.

In another embodiment, said electrical appliance (1) is a motor connected to vehicle axle system In such case the combustion engine vehicle can be converted to the electric vehicle and it can run through the motor without need of combustion engine burning fossil fuels.

In yet another embodiment, said rechargeable battery (2) is an electrical vehicle battery and said electrical appliance (1) is an electrical vehicle’s motor connected to vehicle axle system Thus, in this case also the vehicle can run through the motor without burning fossil fuels.

Preferably, the circular nylon stator (7) has eighteen, twenty four or thirty six slots (9).

Referring to Figure 6, the nylon rotor (11) has magnetic poles (12) selected from a) eight magnetic poles (12) with two blank poles (13) between the first and the eighth magnetic pole; or b) two sets of four magnetic poles (12) said sets are separated by two blank poles (13).

This system find it application in almost every place as it is simple in construction and can be transported to any part of the world. It can be used in agricultural and industrial sectors as well as for household purposes also. Hereinafter the invention is described more elaborately in detail with examples. Examples are merely for illustrative purpose and should not be construed as to limit the scope of invention. Construction and working of the invention:

Example 1: Wagon R Petrol car converted into Electric vehicle

The motor cum alternator system (786) is constructed as shown in the Figures 2 to 4.

The combustion engine was removed from the vehicle and a motor cum alternator system (786) was installed in it. This motor was put in contact with the axel system of the wheel. The 20 Kilowatt rechargeable batteries were used. The vehicle could run for 170 Kilmeter range and with 5 person on load it could run up to 125 Kilometer range. It could touch up to 120 Kilometer per hour, however the speed was limited to 80 Kilometer per hour to get maximum range. After initial 20 kilometer running the pickup was increased. The vehicle was run till 8 hours and the battery was self- recharged.
