Abstract
A system and method are disclosed enabling the use of electromagnetic engines to traverse a wheeled bogie assembly across a plurality of rails. The electromagnetic engines may be used within a rail assembly comprising four rails and a frog assembly. Further, the electromagnetic engines may be used to traverse between a straight path and a turnout path at a non-moving rail switch having a frog assembly. In one aspect, an algorithm for powering various coils is disclosed wherein the algorithm controls the power level to switch tracks connected to the frog assembly.
Claims13
A plurality of electromagnetic engines configured to attach to a wheeled bogie assembly configured to operate on a rail assembly having a left rail, a left-center rail, a right-center rail, a right rail, and a frog assembly, the plurality of electromagnetic engines comprising:
- a first electromagnetic engine, the first electromagnetic engine having a first plurality of coils and being configured to being controlled by a controller;
- a second electromagnetic engine, the second electromagnetic engine having a second plurality of coils and being configured to being controlled by the controller;
- and
- the controller being configured to:
- receive a first signal;
- excite, based on the first signal, the first plurality of coils and the second plurality of coils according to a set of power states, the set of power states defining which of one or more coils within the first plurality of coils and the second plurality of coils are excited, wherein the first plurality of coils comprises a first coil, a second coil, and a third coil, wherein the second plurality of coils comprises a fourth coil, a fifth coil, and a sixth coil, wherein the first signal is a left traversal signal, and wherein the one or more coils excited comprises the first coil, the second coil, the fourth coil, and the fifth coil.
A method for controlling a first electromagnetic engine and a second electromagnetic engine, both of which being configured to attach to a wheeled bogie assembly configured to operate on a rail assembly having a left rail, a left-center rail, a right-center rail, a right rail, and a frog assembly, the method comprising:
- receiving a first signal;
- determining a set of power states configured to cause the first electromagnetic engine and the second electromagnetic engine to excite one or more coils, the exciting resulting in electromagnetic force configured to cause the attached wheeled bogie to traverse laterally across a first plurality of rails;
- exciting, based on the first signal, the one or more coils, based on a set of power states, the set of power states defining which of the one or more coils are excited, wherein the set of power states is configured to cause the wheeled bogie assembly to traverse left or right via a first or second grooved profile section.
