I am back to looking for a lightweight brushless controller.
Since I am building the motor maybe I could wire it for 2 controllers?
I would still need 30kW peaks from each controller.
Dear Sir
Any update from this project
I am starting DIY the motor myself
I start from YASA, researching them, and end up with this thread.
YASA seems to do a lot of improvement in Cooling, lightening while getting big power and torque from the motor by using SMC in the core, rectangular copper wire for winding, fiber reinforced structure for the stator casing.
But I found those designs are only suitable for expensive hyper cars and other mobility application.
For project like yours, we even can accept a little heavier in weight while lower the power/torque a little bit (more losses )
About this axial flux PMSM, the key points are
Cooling
Stator case assembly
Fixing poles in stator
Fixing PM in the rotor
Rotor axial deformation (which is tough because it related to lot of parameters like air-gap ,,,,,)
