Re: Wind and Solar vs Coal, Gasoline, Nuclear

Hopefully the current battery technology is the equivalent of a vacuum tube and when the transistor solid state equivalent with a sodium solid state battery is developed we may well see electric cars with 600 miles range. The theory is there it's just getting a result that works over a long period o...

Re: Tesla Model 3

In just the next few years, the vehicle market will perceive the farting noises of the ICE engine will become representative of adjectives like "weak, toxic, smelly, obnoxious, uninspiring, pointless-complexity and hassles." At this time, no matter how big the brand, if they are tying their brand t...

Re: Tesla Model 3

Sure, lets consider Toyota. They have just a "few" other profitable models for customers to move up to bigger/more luxe, or over to trucks, or eco like hybrids and fuel cell vehicles. They don't rely on Camry folks always upgrading to new Camrys every few years. Do you honestly believe that these g...

Re: Why never see metal cast around wound stators?

Remove the stator completely and have the coils opposing with a an air gap measured in the millionths it wouldn't have heat expansion as an issue so the tolerance can be high. Looking at the super conductors we do have I see there's a limit to their current handling and frequency response before the...

Re: Why never see metal cast around wound stators?

It is better to get thinner laminations! Also, if you can find some (more like make some) square or triangle magnet wire, get way more copper fill and copper cross sectional area. Always good! Then its all about heat management, so perhaps more metal, which adds more weight to soak up the heat to t...

Re: Why never see metal cast around wound stators?

Soon as the room temp super conductor becomes a reality at a price that's cheaper than a neo magnet then we will see some serious shit.

Re: E-Bike XB-502 conversion project

Motors with iron focusing the linkage tend to have voltage as its limiting factor unless it can control it's eddys in an impeccable fashion or the magnet ring is shite so they fling off instead. Where as a dual halbach array ironless axial will have RPM as its limiting factor how fast can it spin be...

Be prepared for huge start up current, I like the connectors I done simular to parallel two cells.

Re: Hover board motors for mountain board

Don't expect to much continuity between them I had 4 motors and only 2 were identical, all the cases had the same pattern size and shape but internally there was different bearings used with differing OD on the stator and the end caps used differing casts. It leads me to believe the manufacturing of...

Re: Why never see metal cast around wound stators?

Induim gets doped with iron to make it magnetic for industrial uses so my educated guess is that over time the Induim will become magnetic at least on it's surface, I don't know if you have look at the galvanic corrosion properties but it's the enamel on the winding that will have to form a seal for...

Thermal grizzly cryonaut cpu paste is a mixture of tin, gallium and indium and that stuff eats into the surface of anything that's not nickel plated, putting it on the enamel of the copper is a risk in itself and this stuff is liquid and thin so it maybe highly conductive but only a thin coat can be...

Re: Pre charge Resisitor?

Yes you need to switch the resistor in then out and over to the main breaker after the system has precharged, you may want to monitor voltage with a multimeter to work out how long the capacitive side of the controller takes to charge if you don't have a volt/amp meter installed.
