2-D inviscid flow the pressures on forward and aft surfaces balance so that no drag is produced, the effect of the boundary layer leads to an imperfect canceling of these pressures so some additional drag is created. Inviscid or vortex drag is produced by the trailing vortex wake of a three-dimensional lifting system.

tooth the same as Figure I-A. Figure I-C is an (8) pole, (18) slot motor with (3) phases and a (2) slot coil winding pitch. Figure I-D is a common brushless configuration for (3) phase motors with (4) poles, (12) slots and a (3) slot coil winding pitch. Figures I-E and I-F are brushless designs with (6) pole imbedded rotor magnets.

ELECTRIC VEHICLE (Construction and Working principle)

In most of the electric vehicle, Brushless DC motor is used which is better than brushed DC motor, permanent magnet DC motor. Brushless DC motor does not have brush and commutator, the electric vehicle which uses brushless DC motor has to use motor controller which helps to control various properties of motor to take sufficient current and
