Displacement factor of Hub motor

[quubik]

I am trying to calculate mosfet losses in a motor controller I am building. For this I need information about motor displacement factor (cos phi).
I use equations from notes-application.abcelectronique.com/070/70-41484.pdf.

I cannot find any information about cos(phi) for BLDC motors. Can any of you suggest a value for typical hub motor? I plan to use 48V 1000W motor. Maybe you could also point me to the source of such information.

The power factor varies with load.
I think that you will have to model the motor
you can use emetor.com
You will be able to see an estimation of it when you use sinusoidal current
I would use 60% worst case scenario so you have to beef things by 1.66 x

Maybe Justin from ebikes.ca can help here
