  Hello, I built a 1/3 model of two Induction Motor for Power Traction Application for Power Traction Application in Maxwell, One is a complete 18-slot model and the other is a complete 18-tooth model. The other settings of the two FEA models are exactly the same, but the torque waveforms are significantly different, and the average torque and torque ripple after stabilization are also significantly different. Why is there a difference?

  Hello, firstly I recommend examining the field analysis and see if the flux is similar in both situations. Afterwards, it would be good to check if there are variations in mesh elements. Such differences could create different results thus you notice different torque in two models that look so similar. Kindly ensure a thorough investigation of these factors.

  This motor is a double layer winding with 3 turns. If I want to use the full 18 teeth for simulation, should the simulation turn setting be as shown?

  Hello, you can create half slots on your axisymmetric model as long as the boundary conditions are correctly implemented.
