Stator slot insulation

Ramin Rahmani

Hi,

How can I consider the insulation of stator slots and conductors using the 3D mode in Flux 2022?

Hi,

To consider of the insulation in the slot and around the conductors in Flux 3D, there is a way to represent both parties. For example you start from a 2D  model (in this model you consider slot insulation and conductors) and you use an extrusion.

Thanks.

Hi Abdessamed,

Thank you for your response. It is possible to consider the thickness of slot insulation in both 2D and 3D models by modifying the slot geometry; however, I am facing challenges in considering conductor insulation. It would be tricky and not accurate to insert round conductors in each slot. Is there any solution, such as an overlay in Flux, that can automatically account for conductor insulation in each slot?

Thank you,

Hamid

Hi,

You are welcome. Yes it is possible to consider the thickness of slot insulation in both 2D and 3D. the conductors, yes you are right it will be complicate to represent all the conductors with insulation in the slot, but you can use an equivalent surface of the conductors (in this case you don’t need to represent all the conductors).

Other solution, you can create your model in FluxMotor (with the latest version you have the possibility to represent the condcutors and the insulation around). Once this is done you export the model to Flux considering the conductors (this leads to represent all the condcutors in Flux with the insulation around).

Other information, when you represent all the condcutors with insulation particularly in 3D, the mesh will be very fine (this increases the number of nodes and time computation).

Thanks.

Hi Abdessamed,

As you said, I have used FluxMotor(2022), which considers the insulation around conductors. However, after I exported the model to Flux, it did not represent the conductors, which can be found as follows

Could you please help me find where my fault is?

Thank you,

Hamid

Hi,

Yes, when you do export from FluxMotor:

• Test selection: select I psi N test.
• Test configuration, click on +. You have an option: represented coil conductors. Form this option you have the possibility to represent the conductors for one phase (all phases).

Thanks.

Hi Abdessamed,

Thank you for the answer. The conductors can now appear in Flux 2D. However, the insulation thickness for both the slots and conductors was not considered in the export from Fluxmotor to Flux, as can be seen below.

Thank you,
