The Tesla Model 3 had the best electronics teardown expert Sandy Munro’s team has ever seen. It had the lowest number of hoses, 40% less harnesses, and the electric motors are smaller, lighter, and more powerful than the competition.
Munro says if Tesla optimizes the Model 3’s production in China, the electric vehicle will generate a lot of profit for the company. Tesla will fix the production line and bodywork issues.
Tesla will have lower labor costs in China.
At about 44 minutes, Munro says Tesla should be able to pull over 20% of the cost of out of the car in the China Gigafactory. Tesla should already be able to make 30% gross margin on a $37,000 Tesla Model 3 car.
Halbach Magnet Critical to Tesla Engine
A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while canceling the field to near zero on the other side. This is achieved by having a spatially rotating pattern of magnetization.
The advantages of one-sided flux distributions are twofold:
* The field is twice as large on the side on which the flux is confined (in the idealized case).
* There is no stray field produced (in the ideal case) on the opposite side. This helps with field confinement, usually a problem in the design of magnetic structures.
Tesla Has a Unique Cooling System
The Tesla cooling system requires crossing over many lines.
