IPM stator circuit

nguyenbach

Description: Hi, i'm running the example "Brushless IPM motor (embedded magnets), and i dont really understand the circuit in there.

1. What are the role of coil conductor and the 2-terminal solid conductor in this circuit ?
2. Can you show me the circuit equation ?
3. Do you think the first image was developed from the second image?

Thanks

Best regards,

Bach Nguyen Viet

Hello Bach Nguyen,

Thanks for contacting Altair.

1. The coil conductor represent the winding of the motor and the 2-terminal solid conductor are assigned to Magnet region. Representing the Magnets as solid conductor in this examples help user to determine the Magnet losses. Refer post processing of Constant speed- Slide 30 in the example- overview document.
2. You can consider the equivalent Circuit of IPM machines. [ In this example, Solid conductor are connected with high resistances, there will be no significant impact due to this representation- The whole purpose of this is to evaluate magnet losses]
3. No, the coil conductor circuit alone is sufficient to run the simulation. You can remove solid conductors and assign the magnet regions back to magnet non-conducting region and run the simulation. Only difference will be you cannot measure losses in Magnets.

Hope this information is helpful.

Thanks,
Charishma.
