abstract

Transient thermal analysis of electric machine under realistic operation conditions and thermal losses is studied. A symmetrical portion of the stator and rotor is modeled and all thermal losses and cooling boundary conditions are applied according to operational duty cycle. It is found that there is a temperature gradient across the stator of more than 30 °C, across the rotor of more than 70 °C and across the whole machine of more than 100 °C. These temperature gradients could cause high thermal stresses and lead to severe reduction in the machine life. It is extremely important in future designs to consider reducing the temperature gradients by optimizing the design of the electric machines through advanced cooling techniques and strategies.
