Abstract:
1. A collector device of an electric train comprising: a collector unit having a first side, a second side and a graphite skateboard, the first side and the second side being the two opposite sides of the collector unit, and the graphite skateboard disposed on the first side, wherein the first side of the collector unit is in contact with a power source having a magnetically permeable capacity via the graphite skateboard, so as to draw an operation voltage; a magnetic unit having an electromagnetic coil body, the magnetic unit configured on the second side of the collector unit for providing an attractive force between the collector unit and the power source so as to reduce a contact loss rate; and a control unit coupled to the collector unit and the magnetic unit; wherein the control unit is configured to adjust a coil current of the electromagnetic coil body according to a current sensing signal or a train speed signal related to the power source, so as to adjust a magnetic force of the magnetic unit; wherein when the train speed signal increases, the control unit increases the coil current, and when the train speed signal decreases, the control unit decreases the coil current.
