Tesla Is Investing $350 Million In Its Gigafactory, Hiring Hundreds of Workers (cnbc.com) 136

Just weeks after the massive Gigafactory started producing batteries, Tesla has announced plans to hire more workers and use the facility to make the motor and gearbox for its upcoming Model 3 electric sedan. CNBC reports: Tesla will invest $350 million for the project, and hire an additional 550 people, according to the governor's comments. That will be over and above the company's existing commitment to hiring 6,500 people at the Gigafactory, according to comments made by Steve Hill, the director of the governor's Office of Economic Development, to Nevada newspaper the Nevada Appeal. Tesla CEO Elon Musk has made manufacturing efficiency a high priority for the company, but Tesla will require a lot of factory floor to meet its goal of to pumping out 500,000 cars by the end of 2018, and then making one million cars by 2020. Meanwhile, the city of Fremont recently approved Tesla's application for an additional 4.6 million square feet of space there.

      So sad. Making cars that don't run on dead dinosaurs, a choice by a crime-infested manufacturer. They should fix up their existing factory and not create jobs for illegal immigrants. Terrible.

    I was curious as to why Tesla needs special gearboxes, but apparently the Model S uses a 9.73:1 single-gear reduction. I guess this lets the engineering team tweak the voltage to torque ratios (as opposed to rewinding the motors and modifying the drive circuitry). https://forums.tesla.com/forum... [tesla.com]

      The Tesla "gearbox" is just a differential to connect the electric motor to the two drive shafts. There is no clutch. There is only one "gear".
      The electric motor has nearly flat torque from 0 rpm up to 16,000 rpm so they don't need to change gears.

      Tesla needs custom gearboxes for several reasons. First of all, being electric it doesn't need a multi-speed transmission. Second, it has to be able to handle a very high amount of torque all at once since an electric motor can generate high torque at 0 RPM with virtually no lag and very low inertia. Tesla worked with several manufacturers for the Roadster transmission and they all failed miserably due to the high torque involved until they designed and built their own.

        Actually they wanted a two speed transmission but every attempt failed. This is why the top speed is limited in the Tesla.
        • What is so difficult about getting a two-speed transmission? I feel like that's something we have a lot of experience designing.......
          • A single speed gearbox is much stronger than a multiple speed one, as all components and force vectors can be optimised.

            Making an equally strong multispeed gearbox must be larger (to accomodate the extra gears) and larger to accomodate heavier components.

            There's only so much space available in the design and automakers have been producing "weak" boxes for a long time on the basis that it increases their servicing business and 99% of drivers never go near the torque peak on a regular or sustained basis.

            Yes,

              That's...........

              • My math teacher at high school was an automotive designer. He related a story specifically about gearboxes and how he was ordered to despec the componentry to ensure they would eventually fail in service

                He quit the industry not long after that.

          The top speed is mostly limited by the battery life - top speed goes with the cube root of horsepower. Increase the top speed by 10% and your "top speed battery life" drops by 30%. Teslas are great toys for US roads, but a joke on the Autobahn.

            20%, not 30%. Wind resistance increases with the cube of speed, but energy-per-mile efficiency (assuming all energy is spent fighting wind resistance) is only squared. That's because you spend less time driving a given distance at higher speed.

            The Tesla P100D's dual motors combine for 760 horsepower, which would be more than enough to sustain 200mph+ with proper gearing and tires. By comparison, a Lamborghini Gallardo achieves a top speed of 202mph with just 562 horsepower. The Tesla's motors redline at about 16000rpm, which at the 9.7:1 fixed gearing ratio corresponds to about 155mph. If the gearing ratio were halved, the low-speed acceleration would reduce but the top speed would go up dramatically.

            True, at 200mph the P100D battery pack would only be good for about 40 miles. But gas supercars don't do much better. At top speed, a Bugatti Veyron can burn through an entire 26-gallon tank of gas in just 12 minutes (51 miles).
            • At top speed, a Bugatti Veyron can burn through an entire 26-gallon tank of gas in just 12 minutes

              But that's OK because IIRC, the tyres are only rated for 6 minutes at top speed.

    • Gear boxes for electric cars are pretty unique because of ratios and torque requirements. Think back ot the several years work to develop a two speed transmission that ultimately failed.
    • Smaller motors running at higher RPMs produce the same output horsepower as a slower/larger motor. The tradeoff is then using a fixed reduction gearbox vs increased motor size. For a great example of this, look at your electric drill vs an AC powered industrial motor of the same output rating

    You were in the running for the Gigafactory but then decided that repaying political favors to your car dealerships was more important and blocked Tesla's ability to sell directly to their customers.

      Nevada got taken to the cleaners on the Gigafactory deal, so I'm sure Texas feels just fine.
    • The key word in the summary is 'hundreds'. It brings the total that Tesla is planning on hiring to 7,000. Nevada is giving Tesla $1.3bn over 20 years, so that works out at $65m/year, or $10K/worker. It's a pretty big gamble that the state will take $10K/year more in tax revenues per worker than if the factory were not there. They're betting that the existence of the Tesla factory will spur other job-creating manufacturing industry.

    Press releases from Tesla are not necessarily news for nerds.
  • " Tesla will require a lot of factory floor to meet its goal of ... making one million cars by 2020. "

    Tesla produced about 25,000 vehicles in Q3 2016, so they'll have to increase that by tenfold in 4 years. Not impossible, but sustaining that kind of growth brings all kinds of challenges, and the auto industry seems to be heading into a bit of a slump. And the incoming administration doesn't seem very green-friendly. Unless you mean the color of money.
  • I really hope these cells become cheap and available to the general public for puchase in small quantities.
  • How did an article on something as positive as the Gigafactory degenerate into a War of the Trolls?!
  • Would be nice to know that citizens are filling these jobs, especially those looking for work.
