TY - JOUR TI - Thermal calculations and testing of external rotor permanent magnet machine AU - Szczypior, Jan AU - Jakubowski, RafaƂ TI - Thermal calculations and testing of external rotor permanent magnet machine AB - 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.
