The work concentrates on the thermal calculations and tests of the permanent magnet machine with an external rotor and cooled with liquid flowing around the inner surface of the stator frame. The distribution of the temperature in the cross-section of the machine, obtained as a result of the thermal net solutions in a steady state is presented. The calculation results are compared with the test results.
This paper presents thermal calculations and tests of a linear induction motor for a model of a personal rapid transit vehicle drive. Various air and liquid cooling systems are analyzed. Laboratory test results of selected solutions are presented. The thermal equivalent circuit model of selected solutions were made. The calculation results were compared with the test results and the most effective solution was selected.
