Abstract
Creating effective synchronous motors with permanent magnets for electric vehicles requires the development of the mathematical models of electromagnetic field to simulate the processes taking into account the rotation of the rotor in real time. Considered a "colector" type of rotor design. Executed the complex of scientific researches which allowed to substantiate the selection of the basic motor parameters, which to provide appropriate power and size, such as: the number of poles, the value of the air gap, the size of the permanent magnets. Investigated the harmonic composition of the EMF of the stator winding and the electromagnetic torque ripple. It is shown that the combined use of a special form of the poles of the rotor and the stator skewed slots significantly reduces the torque ripple. References 6, table 1, figures 6.
