What type of motor is used in large multi-copters? I always assumed those were AC, but am I wrong?
DC Brushless. These motors use Pulse Width Modulation of DC voltage instead of varying AC frequency to control the speed.
Thank you for more proof you know nothing about cars. Super high compression and forced induction are not compatible in any way, shape, or form. Even us knuckle-dragging diesel guys use lower compression pistons and more boost to make number get bigger.
No one is making 400+ hp out of a K24 on 87. Pump gas? Sure, but it's 91 or 93. Lots of turbski guys run E85 to push more boost without going broke driving. AvGas was the redneck E85 of yesteryear. My uncle and his friends used to buy from the crop dusting outfit's bulk tank.
The stuff in RC copters and airplanes are indeed BLDC that are driven by a DC current from the battery and the ESC. I think the confusion lies with the fact 3 wires are used on BLDC motors, which is an AC current but chopped essentially making it like PWM. You can swap any of the 2 motor wires around to reverse direction. The ESC takes the DC from the battery and makes it a 3 phase AC to power the motor. Unlike VFD for induction motors, the ESC doesn't bother with any frequencies as the permanent magnet BLDC motor already produces its own, which the ESC then reads via back emf every off phase (the voltage generated by the motor as it spins) and can adjust speed of the motor by controlling the output voltage. The ESC also essentially acts as the commutator for BLDC motors so it does a pretty big job in timing the motor to attain a balance between efficiency and power.
I literally compared like to like. Same manufacturer, same model year, same trim options. The only difference is the drivetrain, and for that difference, you pay an extra 15k and end up with reduced performance and versatility, and more weight (meaning more more road wear, increasing maintenance costs, and faster tyre wear, which means more expense for the owner).
It was a trailer with a reasonably aerodynamic front, quite typical of the sort of thing a truck would be expected to haul. Both trailers were empty. If you think that's optimised for maximum consumption, then I don't know what to say to you, other than it's clear you also don't understand aerodynamics or towing on top of everything else. They compared it to a 6 litre V8, which ended the test at the same point as the electric with nearly 130 miles of range left in the tank.
It's perfect marketing for the type of people who would buy an EV, the people who don't actually work on their own car. All they know is once in a while they take their car to the shop and spend money. Then comes along the EV marketing of "You won't be doing that anymore! See? Saved money!" without saying "Well, you'll still go. Maybe less often but when you do it will be substantially more expensive".
You bring up some good points on longevity of certain components in EVs. My daily driver right now is a couple decade old German car with nearly 200k miles. Obviously with routine care the engine has proven itself to last, but I have had to get the instrument cluster rebuilt due to some failed electrical components. I also had to replace some old relays for my doors. I am very curious to see what EVs we will see on the road that are 20 years old. The first model year Model S are nearing 10 years and we know that the battery on that is a big expense right now. I don't know how many of those are on the road though. As for the other electrical components? It will be very curious indeed.
based electric motorcycle that's relatively affordable
I'd happily get an electric 2 wheeler if it had either extended range and definitely faster charge time. With the states putting in their own charging networks (let's see them be maintained/updated lmao) I'd be happy with a 2 wheeler that has a 200 mile battery with a 1 hour charge time.
thats gonna be a long while away considering the current level of technology in batteries, sulfur lithium batteries being a number of years away from mass production, the cost of said motorcycle, and the fact most people arent interested in one because of similar reasons as to ebikes or bikes in general
But I thought electric vehicles were supposed to be more reliable and less maintenance!
That's funny because it's another EV utility vehicle fail that TFL group has tested/reviewed. First it was that Ford F150 Lightning towing test and now this Hummer. Oddly enough, Hoovie is now stirring up drama because his towing "test" with the Ford Lightning is the video that caught the attention of Infowars. It really makes no sense because both Hoovie and Alex Jones are saying the same thing about EV pickups and their lack of towing utility. Hoovie just seems to be kvetching over the fact he was mentioned by controversial figure Alex Jones despite it bringing more publicity and revenue for his channel. Maybe it's all an act and Hoovie is just faking it for the drama. Can never tell these days with these youtubers.
to be fair it's gm they havent made a good car in like forever
