Inductive Energy Transmission - Industrial Applications
The system generates electrical energy according to the induction principle, similar to the primary/secondary transmission of a transformer. The transformer comprises a primary and secondary coil on a common, closed ferromagnetic core. This causes a high degree of coupling, however does not allow any relative motion of the two coils between each other. For energy transmission of the used inductive system, the primary coil is "stretched" to a long conductor loop, i.e. the power loop. It is laid in the floor. The secondary coil is wound around the open ferromagnetic core in the pickup and fitted right above the power loop. In this way, a relative motion of the two coils between each other is enabled. The power pickup with its coil arrangement (open transformer) and a controlling device connected internally on the load side, draws power from the magnetic field of the power loop and thus supplies the required direct voltage to the frequency inverter in the connected trolley controller.
As an alternative solution to the linear transmission on the track it is also possible to do stationary charging in parking positions or system required stopping points via charging plates - see next slider.
The charging plate has been designed to power up a 800W floor (flat) pickup. It generates a field corresponding to a 100 A floor loop system. One power module can feed up to 4 charging plates. Alternatively standard floor loops could be used as primary coil.
