All electric motor vehicle
View Patent ↗An improved battery powered four wheel multi-speed all electric motor car, used to move personnel and powered by two multi-wound electric motors connected in tandem so that by engaging the controls three speeds may be achieved. The forward and reverse of the vehicle is accomplished by moving a forward and reverse switch before staring the vehicle by engaging the operating switch. The electrical supply for the vehicle is furnished by batteries charged by a standby rectifier when vehicle is not in use and with solar panel and fuel cell interfacing during daytime operation and the quick removable batteries and hydrogen tanks at exchange stations, if desired by the operator of the vehicle, adds to the uniqueness of our invention by adding to the art of unlimited speed and distance. The interchangeable system of the batteries and the hydrogen tanks on travel routes and the ease which these components can be installed, removed from and replaced in our motor car adds to the many aptitudes of this motor car and to its uniqueness.
1. Drive apparatus for a motor vehicle, said apparatus comprising, in combination:
(a) first and second DC electric series motors coupled mechanically to rotate together and adapted to be connected mechanically to drive wheels of the motor vehicle, said first motor having a first pair of electrical power terminals and a first shunt field winding, and said second motor having a second pair of electrical power terminals and a second shunt field winding;
(b) two input power leads L 1 and L 2 , adapted to be connected to a DC source of electrical power on the motor vehicle;
(c) electric switch means for electrically connecting the input power leads L 1 and L 2 to the pairs of first and second power terminals and to the first and second shunt field windings of said motors, said switch means being operative, when in a first mode, to connect the power terminals of the first and second motors in series between the power leads L 1 and L 2 and to disconnect the shunt field windings; operative, when in a second mode, to connect the power terminals of the first and second motors in parallel between the power leads L 1 and L 2 and to disconnect the shunt field windings; and operative, when in a third mode, to connect the power terminals of the first and second motors in parallel and to connect the first and second shunt field windings thereof, to the power leads L 1 and L 2 ,
whereby the motors operate in a first speed range when the switch means is in said first mode, in a second, higher speed range when the switch means is in said second mode, and in a third highest speed range when the switch means is in the third mode.
2. The drive apparatus recited in claim 1 , wherein the first and second motors are mechanically connected in tandem to a drive shaft of the motor vehicle.
3. The drive apparatus recited in claim 1 , wherein the first and second motors are mechanically connected in tandem to an axle of the motor vehicle.
4. The drive apparatus recited in claim 1 , further comprising a DC source of electrical power coupled to said power leads L 1 and L 2 .
5. The drive apparatus recited in claim 4 , wherein said DC source includes a battery.
6. The drive apparatus recited in claim 5 , wherein said battery is replaceable.
7. The drive apparatus recited in claim 4 , wherein said DC source includes a solar panel.
8. The drive apparatus recited in claim 4 , wherein said DC source includes a fuel cell.
9. The drive apparatus recited in claim 8 , wherein said fuel cell is connected to a replaceable source of hydrogen.
