A thermal capacitor stores thermal energy. For systems that do not experience phase change or chemical (or nuclear) reactions, the thermal capacitance relates the stored energy to the temperature (E = C (T − T ref)), where the stored energy is set to zero at some reference temperature, T ref.
The value of the thermal conductivity is associated with the temperature of the machine in a certain operation regime . The thermal capacitance is a measure of the ability of the motor to store energy as heat. It is an important parameter that is related to the transient temperature behavior.
The thermal circuit for a multilayer ca-pacitor is complicated because there are many parallel thermal paths. Since the current varies over the length of the capacitor, the power dissipation is not concentrated at any one point in the ca-pacitor, but is distributed throughout the length of the capacitor.
