Nowadays electrical vehicles are more common due to several aspects that sets forward the spreading. One of the most important reason is that the fossil energy sources of the Earth are not infinite. The other reason, which is relevant from an environmental perspective, is the internal-combustion engine. It is especially important when it comes to cities in which air pollution increased in the recent decades. Consequently, beside of the environmental awareness, the electric vehicle’s efficiency is much better than of gasoline or diesel cars.
The electrical cars’ source of energy is the accumulator, which is at the same time their biggest disadvantage too, because at present, the range of this vehicles is much less than cars with internal-conbusion engine. Therefore, to reach the maximum range, it is necessary, to improve the efficiency these motors, and reduce weight, as these are carried with, and operate at the expense of range.
One of the most important part of the cars is the blower motor. Its function provides not only the comfort of the passangers, as it provides steam on the windscreen, and removes condensing humidity from it, so it has safety function as well.
In my thesis, I will present the elementary designing steps of a blower motor, from selecting the type of the motor to the determination of the basic electrical parameters.
