Overview

Closeup |
In recent years, the importance for methods to handle heat is growing as
electrical equipment is miniaturized and designed for high power.
The thermal conductivity and heat transfer coefficient needs to be modeled
correctly to accurately evaluate the heat dissipation characteristics of
electrical equipment. Therefore, if each part can be modeled correctly,
the characteristics of the entire device can be evaluated.
This example presents the use of a thermal analysis to obtain the thermal
conductivity of each part using basic cubes assuming they are a rotor core
and stator core of a rotating machine. The results for each part are evaluated,
and then compared to the theoretical calculation to evaluate their accuracy. |
Temperature Distribution
| The temperature distribution of Part 1 and Part 2 are indicated in Fig.
1. The temperature varies linearly from the exterior to interior of each
part. |

The analysis results and theoretical calculation for the temperature inside
Part 1 and Part 2 are indicated in Table 1. The analysis results and the
theoretical calculation match. For this reason, we can assume that the
analysis results that are obtained are accurate. |
