Abstract
The results of a numerical and experimental study of an electric machine with cylindrical permanent magnets are presented. It is shown that if a squirrel-cage rotor in a standard induction motor is replaced by a rotor with permanent magnets, then a significant increase in the specific power of the electric machine can be obtained. Numerical studies and analyses of the characteristics of an electric machine with tangentially magnetized neodymium and ferrite magnets in the motor mode have been carried out. It is shown that in order to ensure maximum specific characteristics for use in electric vehicles, it is necessary to take into account the driving cycle and carry out liquid cooling of the electric motor. Also, a comparison of the characteristics obtained during testing of an experimental sample in the generator mode and the characteristics obtained in the calculation models was made. It is shown that the discrepancy between the calculated and experimental dependences for several values of the rotor speed is no more than 4%. The characteristics of the electrical machines under study were calculated using the Simcenter MagNet and Simcenter MotorSolve software packages. References 7, figures 6, tables 2.
