Re: The Real! MUSTANG MACH E is here

You've got your facts wrong as far as how those motors create torque and use current...good luck. If you would like to quote any "facts" you disagree with, I can show you where you are wrong, otherwise your post belongs in the same category as this masterpiece. Electric cars are nothing more than a...

Re: The Real! MUSTANG MACH E is here

Bear in mind I'm not designing electric cars for a living, so I can only speculate on what they do. When reading up on the subject I note that the Tesla's seem to have a reduction gear to increase torque to the wheels. This obviously would reduce the top end speed substantially (I read somewhere tha...

When you use VFD the curves look something like the ones on this page:

Re: The Real! MUSTANG MACH E is here

And then this: They claim 1419 HP for the car. This can only be the case when they work with 60 Hz. The synchronous RPM is 3600 in that case, or 3564 rpm at 1% slip. This also means that they are using the breakway torque for acceleration, which is roughly with 10-12% slip and when assuming 11% slip...

Re: The Real! MUSTANG MACH E is here

some considerations: Assuming a well built asynchronous motor with about 1% slip, it would turn around 2970 rpm (with 2 poles) at optimal working rpm. I read that the car in the subject has 2300 ft lbs torque or 3.162,5 Nm. This means that it would produce 983,10 kW at that rpm and assuming 50 Hz AC...

Re: The Real! MUSTANG MACH E is here

So we're ignoring the questions, ok, whatever. BTW: the electric motors in the EV's (most use AC motors due to their better power density) are driven by 3 phase power, so the formula you used is wrong :D (P = 1,73 * U * I) More so, most cars run their motors at 350V or 375v. So try to recalculate an...

I am sure all here are equally convinced by the facts you have quoted and the sound logic used to reach your conclusion.

Re: Quiet external EFI fuel pump experience

Guys Bosch 044's get noisy as hell also when you get the fuel hot. The key to using a high flow after market pump on the street is to pulse width modulate it at low demand so it flows less fuel keeping the fuel in the tank cooler. Except that if you use an aftermarket pulse-width modulation system,...

Re: The Real! MUSTANG hwMACH E is here

You can assume anything you want. I don't care. Are you going to debate that an electric motor (any type) when being in a high torque, low speed situation is going to draw a lot of amps ? Are you going to debate that drawing that much amps means a lot of power is consumed, power that needs to come f...

Re: The Real! MUSTANG MACH E is here

Like with all cars hp says nothing. It's a mathematical equasion that is based on torque. The more torque at low rpm the higher the calculated hp will be. Since all electric motors have a lot of hp at very low rpm, evidently the amount of HP is going to be high. I do not debating that an electric mo...
