Abstract

Since the resolver is placed very close to the motor and there is a risk that leakage magnetic flux will effect detection accuracy, it is necessary to confirm how the leakage magnetic flux from the motor effects the resolver.
On the other hand, actual measurement of leakage magnetic flux is difficult, and it is expected that the phenomenon will be understood through FEA, and a modeling method must be established.
In this presentation, we will analyze the leakage magnetic flux from the motor that is applied to the resolver. To evaluate the leakage magnetic flux, it is necessary to model the surrounding magnetic bodies, the analysis can be done by modeling magnetic bodies such as bolts. We will discuss that it is possible to perform effective evaluations, and that it is possible to calculate realistic times for large-scale models by performing parallel calculations.
