[Analysis Case] Air Gap Magnetic Flux Density Analysis of Built-in Magnet Synchronous Motor

Understanding the magnetic flux density in the air gap is important! Here are some examples of magnetic flux density analysis for the relevant area.

We would like to introduce the "Air Gap Magnetic Flux Density Analysis of Interior Permanent Magnet Synchronous Motors (IPMSM)" conducted by our company. The analysis mode used was transient response analysis, and the driving conditions were no load at 3,000 min-1, with the analysis executed at the 45° position in the right diagram for 1/8 of the section (2D). As a result of the analysis, it was found that the magnetic flux density penetrating the air gap between the stator and rotor changes relative to the excitation timing of the stator coil with respect to the rotating rotor. Therefore, analyzing the dynamic behavior is considered an effective approach. 【Analysis Conditions】 ■ Analysis Mode: Transient Response Analysis ■ Motor Specifications: 3-phase / 8-pole / 48-slot, distributed winding ■ Driving Conditions: No load / 3,000 min-1 ■ Analysis executed at the 45° position in the right diagram for 1/8 of the section (2D) ■ The air gap (air layer) between the stator and rotor is processed in 4 layers *For detailed information about this case, please refer to the related links.
