Transport system incorporating linear motor charged electric vehicle
View Patent ↗A system and method are provided for moving a vehicle along a roadway. The system includes at least one power segment that incorporates a multiple-phase winding. Structurally, the winding is embedded into the roadway for interaction with a magnet system mounted on the vehicle. With this interaction, a Linear Synchronous Motor (LSM) is established between the roadway and the vehicle to drive movement of the vehicle along the roadway. Also, the vehicle includes a mechanism for initially synchronizing a waveform speed of the multiple-phase winding with the speed of the vehicle. Further, the vehicle is able to selectively establish the LSM for use when desired.
1. A system for moving a vehicle along a roadway which comprises:
at least one power segment having a three-phase winding embedded into the roadway for interaction with a magnet system mounted on the vehicle to establish a Linear Synchronous Motor (LSM) therebetween for movement of the vehicle along the roadway;
a means on the vehicle for initially synchronizing a waveform speed of the three-phase winding with the speed of the vehicle; and
a means on the vehicle for selectively establishing the LSM.
2. A system as recited in claim 1 wherein the waveform speed is constant.
3. A system as recited in claim 2 wherein the waveform speed is approximately 15 mph.
4. A system as recited in claim 3 wherein the LSM operates at approximately 15 Hz.
5. A system as recited in claim 1 further comprising a propulsion drive mounted on the vehicle, wherein the propulsion drive is selectively activated to move the vehicle along the roadway as an alternative to the LSM.
6. A system as recited in claim 1 further comprising a stainless steel top plate covering the power segment.
7. A system as recited in claim 6 wherein the winding is embedded in reinforced concrete.
8. A system for moving a vehicle including a magnet system along a roadway which comprises:
at least one power segment having a three-phase winding embedded into the roadway for interaction with the magnet system to establish a Linear Synchronous Motor (LSM) therebetween for movement of the vehicle along the roadway;
a means on the vehicle for initially synchronizing a waveform speed of the three-phase winding with the speed of the vehicle; and
a means on the vehicle for selectively establishing the LSM.
9. A system as recited in claim 8 further comprising a propulsion drive mounted on the vehicle, wherein the propulsion drive is selectively activated to move the vehicle along the roadway as an alternative to the LSM.
10. A system as recited in claim 8 wherein the waveform speed is constant.
11. A system as recited in claim 10 wherein the waveform speed is approximately 15 mph.
12. A system as recited in claim 11 wherein the LSM operates at approximately 15 Hz.
13. A system as recited in claim 8 further comprising a stainless steel top plate covering the power segment.
14. A system as recited in claim 13 wherein the winding is embedded in reinforced concrete.
15. A method for moving a vehicle including a magnet system along a roadway which comprises the steps of:
embedding at least one power segment having a three-phase winding into the roadway;
interacting the power segment with the magnet system to establish a Linear Synchronous Motor (LSM) therebetween for movement of the vehicle along the roadway;
initially synchronizing a waveform speed of the three-phase winding with the speed of the vehicle; and
selectively establishing the LSM.
16. A method as recited in claim 15 wherein the waveform speed is constant.
17. A method as recited in claim 16 wherein the waveform speed is approximately 15 mph.
18. A method as recited in claim 17 wherein the LSM operates at approximately 15 Hz.
19. A method as recited in claim 15 further comprising the step of covering the power segment with a stainless steel top plate.
20. A method as recited in claim 19 wherein the embedding step comprises embedding the winding in reinforced concrete in the roadway.
