First, one thing to be aware of is that like the resistance the inductance is also measured to the center, so you have to double it as well to get the value between two motor terminals.
I have already spent so much time explaining, so I made a simulation. The simulated inductor has 50 µH and 40 mOhm. I made a transient simulation with 20 kHz frequency and enough duty cycle to reach around 110A in steady state.
This is the circuit:

This is the transient:
- sim1.png (24.82 KiB) Viewed 2878 times
Zooming in you can see the average current related to the PWM pulses. As you can see, the inductor current is almost constant at 110 amps with very little ripple:
- sim2.png (26.04 KiB) Viewed 2878 times
zooming in on the ripple, it looks like this:
- sim3.png (29.52 KiB) Viewed 2878 times
You can see that it is around +- 2 amps. In BLDC mode the switching frequency is 40 kHz, and then the ripple is +- 1 A:
- sim4.png (32.16 KiB) Viewed 2878 times
The simulation file for ltspice is also attached. If you want to play around with it ltspice can be downloaded for free and runs nicely in wine under linux if you are like me and don't use windows.
So yes, the motor will see nearly a constant current even though there is PWM and the losses are exactly as I explained.
