Axial Flux Motors
A reader asks what I know about axial flux electric motors. He says:
For some time, they have been recognized as having potential to reduce motor weight, cut costs, and improve motor efficiency, however there was a problem – how to lose unwanted heat.
An Oxford based company Yasa – recently bought by Mercedes-Benz has changed that by working out how to keep these motors cool. Their latest motor weighs 24 kg and is capable of delivering 590lb ft of torque, 480 hp of power, has reached 98% efficiency.
I have some familiarity with the subject, and I just watched a cool video on it, but I’m not a go-to person on axial vs. radial flux motors. If there is some significant improvement in power/weight and/or torque/weight, that is a distinct advantage.
Keep in mind, however, that the total efficiency of charging and discharging batteries through our current-day electric motors is already very high, which means there is very little area for even theoretically possible improvement.
Here are a few thoughts from one of our founding fathers, who stood among the most enlightened and intelligent people of the day.
I will be surprised and deeply saddened if this ends poorly for her.
It’s hard to remember how Liz Cheney comes down on any other issue than justice for Trump. As I recall, she is fairly conservative, meaning that most 2GreenEnergy readers don’t have too much in common with her politically.
At this point, few of us remember Shai Agassi and his enterprise “Project Better Place.” He proposed to place EV battery-swapping stations strategically across the nation, a concept that would have virtually eliminated “range anxiety” and made charging one’s car as quick and innocuous as filling one’s car.
It’s common for Americans to lament that things like penmanship (cursive) are no longer taught in our schools. I’ve never been too sympathetic here, on the basis that there are only so many minutes in a school day, and everything we add in comes at the expense of losing something else.
Herschel Walker is a pathological liar, but that’s only one reason that he’s no more qualified to be a U.S. senator than he is to be a board-certified cardiac surgeon.

What would it be like to know that you could eliminate world hunger, or tackle climate change, but decide to develop a hobby that requires tens of billions of dollars?
