Brushless DC motor for battery-electric trucks

Inhalt:
Modern calculation methods do more possibilities to designers of electric machinery. They allow on development of electric machines as well as upgrade of existing machines and devices. Often upgrading of a motor is much more complicated than designing a new one, as customers impose limitations concerning power supply, price, dimensions, etc. The example of such application of calculation methods is development of a motor for battery-electric truck produced in Poland and designed for transport of various types of materials, with loading capacity of 2000kg. Presently series commutator DC motors are installed in battery-electric trucks. The disadvantage of such motors is their too low efficiency, too big size, and too high noise emission. Hence the need to develop modern motor for battery trucks, with better technical parameters, lesser operational noxiousness, including lesser noise emission. Such requirements can be met by new generations of brushless DC motors featuring i.e. higher efficiency and durability, and lower noise emission than motors currently installed in said vehicles.
