When calculating the radial force of the motor teeth (multiple single teeth) and performing FFT decomposition, in order to accurately obtain the spatial order and time frequency order, should the whole tooth or only the tip part or other parts be taken?

[Timotheos Fetsis]

Hello, there is no need to calculate the force on the whole tooth. The force is calculated by intergrating surface force on all surfaces of the object surrounded by air. In both cases a small difference is expected because of the intergration points being quite different (mesh).

Okay, Timos，thanks！ That is to say, the position of the 4 cutting teeth as shown in the figure is all OK, but because of the factors such as division, the calculated force will be somewhat different, right?
