Abstract: A method of determining a path comprises obtaining a path in a road net, the road net comprising a plurality of nodes; calculating, with a processing device, an event displacement probability within coverage of the path, wherein the event displacement probability is used to describe a possibility of displacement of an event that could have occurred within the coverage of the path, to outside the coverage of the path to occur; and changing the path based on the event displacement probability.

Abstract: A traction motor for an electric vehicle, comprises a stator and a rotor rotatably mounted to the stator. The rotor comprises a rotor core and magnets fixed to the rotor core. The rotor core has 2P rotor poles formed by the magnets, P being an integer greater than one. The stator comprises a stator core having S teeth and field windings wound on the teeth, S being equal to 3·m·P where m is the number of phases. Field windings of each phase comprises P winding units. Each the winding unit comprises a first coil and a second coil connected in series. The first coils have a larger coil pitch and a greater number of turns compared to the second coils.

Abstract: An engine cooling system includes an engine, a coolant tank, a radiator, a cooling module for cooling the radiator, and connecting pipes connecting the engine, the coolant tank and the radiator to form a loop. The cooling module includes a motor and an impeller. The motor includes a stator and a rotor. The stator forms 2P stator poles, wherein P is a positive integer. The rotor includes a shaft, a rotor core, and windings wound around the rotor core. The rotor core includes n teeth and forms n winding slots between the teeth. A slot has a radial depth less than one of the other slots. The number of winding slots n is a multiple of the number of stator poles. The windings includes coils each of which is wound about n/2P teeth.

Abstract: A DC motor 12, has a stator housing 16 accommodating a permanent magnet stator and a rotor 15 rotatably mounted confronting the stator. The rotor 15 has a shaft 21, a rotor core 22 fitted to the shaft and having laminations forming salient poles or teeth 27. A commutator 23 is fitted to the shaft adjacent one end of the rotor core and windings 24 are wound about the teeth and terminated on segments of the commutator 23. The windings is formed by a number of coils with each coil being wound around a single tooth of the rotor and each tooth supporting a single coil. Brush gear comprising a plurality of brushes 26 in sliding contact with the commutator 23, transfers electrical power to the windings.
