A system for transferring electric energy to a vehicle. The system comprises an electric conductor arrangement which produces an alternating electromagnetic field, transfers electromagnetic energy to the vehicle, and includes a plurality of consecutive segments. Each segment extends along the path of travel of the vehicle. The system includes an alternating current supply for conducting electric energy to the segments which are electrically connected in parallel to each other with the alternating current supply. Each segment is coupled to the supply via an associated switching unit adapted to switch on and off the segment by connecting or disconnecting the segment to/from the supply. Each segment is coupled to the associated switching unit via a constant current source adapted to keep the electric current through the segment constant while the segment is switched on independently of the electric power which is transferred to one or more vehicles.

System and method for transferring electric energy to a vehicle using a plurality of segments of a conductor arrangement

A system for transferring electric energy to a vehicle such as a track bound vehicle or road automobile. The system includes an electric conductor arrangement which produces an alternating electromagnetic field, transfers electromagnetic energy to the vehicle and includes a plurality of segments. Each segment extends along the vehicle path of travel and includes one line for each phase of alternating current carried by the segment. The system includes a current supply for conducting electric energy to the segments which are electrically connected in parallel. At least one segment is coupled to the current supply via a constant current source. Each constant current source includes one or more inductances and one or more capacitances, the inductances and capacitances being adapted to each other and the input side of the constant current source so that a constant current is output to the output side.

The invention relates to an arrangement for providing a vehicle, in particular a track bound vehicle, with electric energy, wherein the arrangement comprises a receiving device () adapted to receive an alternating electromagnetic field and to produce an alternating electric current by electromagnetic induction. The receiving device () comprises a plurality of windings and/or coils () of electrically conducting material, wherein each winding or coil () is adapted to produce a separate phase of the alternating electric current.

Inductively receiving electric energy for a vehicle

The invention is a system for transferring electric energy to a vehicle. The system includes an electric conductor arrangement for producing an alternating electromagnetic field and for thereby transferring the energy to the vehicle. The electric conductor arrangement includes at least one alternating current line, wherein each alternating current line carries one phase of an alternating electric current. The conductor arrangement includes a plurality of consecutive segments, wherein the segments extend along the path of travel of the vehicle. Each segment includes one section of each of the at least one alternating current line. The system also includes a direct current supply line for supplying electric energy to the segments. Each segment is connected to the supply line via at least one inverter which inverts a direct current carried by the supply line to an alternating current carried by the at least one alternating current line.

A track brake control system for providing braking of a railway vehicle operates upon receipt of an emergency braking command. The control system includes a member for receiving deceleration information from one or more sensing devices. The control system further includes a member for comparing the deceleration information with a reference value or reference profile. Further, the control system includes at least one regulating device for continuously adjusting a braking demand signal to a track brake so as to cause deceleration of the railway vehicle based on the comparison.

Track brake controller

The invention relates to a system for transferring electric energy to a vehicle, in particular to a track bound vehicle such as a light rail vehicle, wherein the system comprises an electric conductor arrangement for producing an alternating electromagnetic field and for thereby transferring the energy to the vehicle, the electric conductor arrangement comprises at least two lines, wherein each line is adapted to carry a different one of phases of an alternating electric current, the conductor arrangement comprises a plurality of segments, wherein each segment extends along a different section of the path of travel of the vehicle, each segment comprises sections of the at least two lines and each segment can be switched on and off separately of the other segments.

A primary of a linear induction motor has a plenum formed on its upper surface to receive cooling air from a fan. The upper surface of the core is formed with fins to promote cooling. Air flows from the plenum to side housings in which the end turns are located. A deflector plate directs air from the plenum over the end turns of the windings. Exhaust slots are provided in the housing above the end turns and a baffle between the housing and the end turns promotes flow through the end turns as it moves toward the exhaust slots.
