<p>The method involves providing a stator (2) having a yoke (5) on which electrical conductors are wound so as to form coils (6-1-6-6). The coils are connected to a power supply device e.g. power grid, so that each coil is crossed by electric current (i2) delivered by the device. The stator is connected to the device, so that a phase shift between another electric current (i1) traversing one of the coils i.e. reference coil, and the former current at other coils varies in a strictly monotonous way as displacement of the reference coil when the reference coil is moved around a stator axle (X). Independent claims are also included for the following: (1) a method for charging a battery from a power supply device (2) a system comprising a stator and a power supply device.</p> |
