[JAC296] Torque Characteristic Analysis of an IPM Motor Accounting for Temperature Distribution and Changes in Temperature
In order to realize the high efficiency and high output of motors, it is necessary to understand the temperature increases that occur in each part of a motor. This is because coil resistance and magnet characteristics change with increases in temperature, and this may result in motor characteristics being largely affected.
Although it is difficult to understand the temperatures of each part in a real machine, the temperature distribution of each of these parts can be obtained with ease through simulations, and changes to characteristics due to increases in temperature can also be accounted for.
In this example, magnetic field and thermal coupled analysis is run, and changes in torque due to part temperatures and magnet demagnetization are checked.
Please see the website for “Changes in Temperature, Average Temperature, Copper Loss, Temperature Distribution” and “Magnet Operating Points, Torque Waveforms”.
