Andrej Kačenka

ESR1 finished in March 2020 his working period at Brose Fahzeugteile where he was developing the Lumped parameter thermal models for temperature determination of PMSMs used for Power steering applications. The results of his work were presented at the virtual conference ICEM2020.

Since April 2020 he is working as a Research assistant at UTCN where he is dealing with the electromagnetic and thermal modeling of electrical machines using Finite Element Method. He became familiar with the simulation tool Flux2D for performing electromagnetic and thermal FEA of various types of electric machines. At first, he focused on electromagnetic modeling of the Squirrel cage asynchronous motor with copper bars for Air conditioning compressor applications. He simulated a steady-state magnetic AC study in order to determine the average torque of the machine, motor characteristics for the rated load operation, parameters of the equivalent circuit. Later, he continued with the transient study. The purpose of this simulation was to reproduce real working conditions of the motor, from the starting to the addition of the rated load to display main quantities, like speed, torque, current. Moreover, the purpose of the magnetic study was to provide the heat sources that represents input data for the steady state-thermal analysis. This study is to be performed for both Induction motor and PMSM’s stator for which the LPTN model is already developed.
