Simulating a curved SLIM

    • ae18b021

      Hi everyone,

      I'm trying to obtain a transient simulation of a curved Single-sided Linear Induction Motor rotating a disc. This model is very similar to an induction motor. However, the obtained results did not match the expected analytical results.

      The LIM has a curved shape with 61 teeth and 60 slots.

      The number of slots per pole per phase is 3.

      The tooth height is 53.25 mm, slot width, coil width, and tooth width is 11.111 mm, coil height is 0.5*tooth height.

      The wheel's radius is 70cm, and the airgap is 6 mm.

      Can you provide us with more information and screenshots on how is the motion setup done?
      Is the Eddy current effect for the rotor is checked on or not? It needs to be checked.
      What is the number of poles and frequency of operation?

      Regards Navya

      Thanks a lot for your response and sorry for the delay in response.
      We wanted to confirm that yes, we did check eddy currents for the rotor. The number of poles is 7 (since it is a linear induction motor, an odd number of poles is allowed). The frequency we have given here is 375A, and the time step for our simulation is 0.5ms. Please find below the screenshots of the motion set-up.
