| Sumario: | The results of experimental research and thermal analysis of several types of
cooling of brushless electric motors with nominal power 10-12kW (PMAC),
suitable for “light” EV/HEV vehicles are presented in the research paper.
The studied motors have permanent magnets, a double stator and an axial
magnetic flux with air or liquid cooling. The Motor-CAD software performed
the presented thermal analysis. The experimental study was made on the basis
of precision results, obtained from the measurement of process temperatures
during operation in a real-world environment. For this purpose, the electric
motors were equipped with a number of thermocouples with which the
temperatures are measured. The precise measurement and recording of the heat
flux temperatures is performed using LabVIEW software. The calculations from
the thermal analysis coincide with the experimental results and can be used
to predict the heat fluxes in different designs and types of cooling
systems. The possibilities for improving the cooling and power of standard
PMAC electric motors with double stators have been studied and analyzed. |
