[Analysis Case] Demagnetization Analysis of Interior Permanent Magnet Synchronous Motor (IPMSM)

Predicting the demagnetization state due to external factors that cause a magnet to lose its magnetism through analysis!

We would like to introduce the "Magnet Demagnetization Analysis of Interior Permanent Magnet Synchronous Motors (IPMSM)" conducted by our company. The analysis mode is transient response analysis, and the motor specifications are 3-phase, 8-pole, 48-slot, with distributed winding. The driving condition is 3,000 min^-1. As a result of the analysis, it was found that the demagnetization occurs at locations on the rotor core where the magnetic flux density is high, and it was also determined that the surrounding temperature of 125°C affects the coercivity reduction of Nd-Fe-B magnets. 【Analysis Conditions (Partial)】 ■ Analysis Mode: Transient Response Analysis ■ Motor Specifications: 3-phase, 8-pole, 48-slot, distributed winding ■ Driving Condition: 3,000 min^-1 ■ Magnet Surrounding Temperature: 125°C ■ Location of Electrical Short Circuit: Between Stator Windings *Details of the case can be viewed through the related links.
