Cable-drawn conveying device and method for operating such a device
A system and method to ensure a sufficient amount of electrical energy is supplied to a cable-drawn vehicle of a transportation device. Electrical loads of the vehicle are supplied with power outside a station by an electrical energy store of the vehicle or by both an electrical energy store and the generator during a first movement phase, in which the vehicle is accelerated to a limit speed or, conversely, decelerated from a limit speed into a station. In a subsequent second movement phase, the vehicle is supplied with electrical energy by the generator while the vehicle moves at a speed that is greater than the limit speed.

Cooling of an electric motor
An electric machine comprises a housing (9) enclosing at least a rotor (5) and stator windings (4) of a stator (2) of the machine and comprising an end shield (10, 11) at each axial end of the machine. The housing has an air inlet (15) at a first axial end (12) of the machine and a peripheral air outlet (16) at the other, second axial end (13) of the machine. A fan (17) is arranged in the housing at said second axial end to rotate with the rotor for creating a flow of air through the housing from the air inlet to the air outlet for cooling parts of the electric machine. An air outlet channel (19) conducts air radially leaving the fan to the air outlet (16). This channel has a first channel portion with first walls (21) directing air leaving the fan (17) axially back in the direction of the first axial end (12) and a second channel portion with second walls (23) redirecting the air flow from the fan to assume a major radial component.

System and method for managing the energy supplied to a transport vehicle, and corresponding transport vehicle
A system and method are for managing the energy supplied to a transport vehicle. A first and a second source of energy provide electrical energy to power at least one piece of consumer equipment of the vehicle. An intermediate energy transmission system receives electrical energy provided by at least one of the two sources of energy and transfers it to the at least one piece of consumer equipment. An energy conversion-control system applies, at the input of the intermediate energy transmission system, the electrical energy to be provided, adjusted depending on the operational state of the first source of energy and on an input signal indicative of an operational state of the second source. The first source of energy includes an internal combustion engine connected to a permanent-magnet alternator that is placed between the internal combustion engine and the energy conversion-control system.
ARC DETECTION AND RECORDING IN ELECTRIC TRAINS, SUBWAYS, STREETCARS AND BUSSES
A device and method for detecting a location of an arc event between a power bus and a coupler of an electric vehicle monitors an interface between the power bus and the coupler for the occurrence of an optical event. A determination is made if an arc event occurred based on the optical event, and upon determining the occurrence of an arc event at least one of a time the arc event occurred or a position of the electric vehicle at the time the arc event occurred is recorded.
Form-wound coil having previous winding of mica tape
A coil of a stator winding of an electric machine is formed of a number of windings, which are wound together with a number of layers of a mica tape, on which a number of layers of a cover tape are in turn wound. The coil is a three-dimensional form-wound coil. The mica tape has a bending stiffness of less than 50 N/m according to specification IEC 60371-2:2004 and a static friction coefficient between the top side and the bottom side thereof of less than 0.7 according to specification ISO 8295:1995.

Solar Personal Rapid Transit System with Autonomous Pods
The solar personal rapid transit (PRT) system is configured to provide a transportation system with higher material, energy, environmental, and economic sustainability. The solar PRT system includes autonomous vehicles or “pods” that travel on a rail guideway above the pods. The pods are configured for moving people and objects from one location to another along the rail guideway. Each pod is coupled to a drive unit via a hanger for moving the pods through the guideway. The drive unit includes wheels with flanges proximate to the outside edges of the guideway rails. A combination of tongue tracks and a switch blade is used to route the pods onto different tracks. A pre-tension frame supports each section of the guideway and includes a smart cushion that changes the length of the section based on environmental temperature. The smart cushion is further used with a BIPV module for a roof.
