Australian Model 3 Waiting Room

Could it be a water pump, to transfer fluid/heat from motor to battery?
What's the scale of those windings, as they seem a bit large to be a sensor, more a motor.

I think it is the angle sensor, they are called resolvers.

If it’s the one at the very end. That’s more of a speed/angle sensor. It’s an induction sensor not a Hall effect sensor, hence the windings.

Okay, I think the right term for it is the inductive resolver. I think there are atleast 2 of them in each of the drive unit.

Here is the most helpful documentation I can find about these resolvers:

Discover why high-speed inductive resolver simplifies automotive electrification

This tech-talk provides the basics on the principle of inductive sensors. It also compares technologies used in high-speed sensing applications such as e-motors, e-brake boosters and e-power steering.

For my pick up today I had my nephew who has the original model 3 from 2021 and he went through and checked everything from top to bottom of the car. He found a few scratches and imperfections in the paint that we noted down already and have booked in to get checked out in a couple of weeks. The parcel shelf appears to be well fitted with no rattles so far. Concerns about panel gaps etc were non existent but we did also find that the underneath of the bumper bar was poorly manufactured with a small kink which the Tesla guy says he suspects it’s within tolerance so bad luck. Good thing it’s not easily visible as you need to look under the car to notice it.
There were probably another 5-6 people who came for their pickup whilst I was there as well.
Can't help flooring the car and testing the dual motors with a stupid grin on my face.

 

[jeevas123]

Got the car and made it home in one piece. Pity it was raining most of the way. I didn't find the wipers too bad, maybe they could be a touch more sensitive. Now it'll probably sit in the garage for a week until I do the ppf and ceramic/Graphene coating.

In case of such emergencies Just yell "Hey xxxxx tesla turn on the xxxxx wipers for xxxxx sake"

I was thinking of creating a checklist so that my excitement won't overpower my duties during delivery..

No no. I think the oil circulation in the drive unit is driven by the main motor itself and the coolant flow is driven laterally thru the super manifold as shown below:

There is a separate electric oil pump at the very bottom of the DU. Main motor won’t circulate oil when stationary.

Yes that pump is paired with a separate electric motor but just mechanically coupled with the main motor. I may be wrong as I didn't do any disassembly myself.

And why we need to circulate oil when stationary on such a simple gear system?

Edit: Confirmed Oil pump is a separate low voltage electric motor.

 

[NoPistons]

Whats your build date?

December 23

 

[Jules22]

@dronus have you got this accessory yet?

It’s an electric oil pump. Which is basically another motor.

Cooling.

Getting the whole car ppf'd or just the front? I was quoted $3500 for full front ppf, Graphene coating, ceramic tints inc full rear window and interior protection

You are absolutely right. It is another LV ~16v motor at ~4amps.

Who quoted this? Address please.

Edit: Oh full front ppf, misread as full car.

I might get my parcel shelf ppf’d

yeah, or start making more babies, I feel like we have to now that ADR have made such a big fuss about this middle bloody tether!

Good dog tether

Just tell the partner you need more practice, pretty weird excuse to try and explain i guess

For those with cars on Paganella, I’m hoping because they had to fly the new shelf in from Shanghai, and that our (mine atleast) build dates are 09 Jan, maybe ours will already have the new shelf. Means straight to the DC for delivery!

I happened to be in Tesla Alexandria this arvo, and asked the question: are the cars on Paganella built with correct parcel shelf, or do they require re-work. SA could only answer that 'we aren't given that information'. I'm hoping your speculation is correct!
