  • In addition to the induction motors mentioned by the other postings, the new Tesla Model 3 uses an entirely new type of electric motor, which is technically.

    and now why Tesla uses induction motors Brushed DC motors can run directly off a battery but the type of motor you are looking at in an.

    Tesla is a well-known manufacturer of electric vehicles. The company's founder is not Ilon Mask, as many believe. Mask is one of Tesla's main sponsors and her public face. The company has an interesting principle of work - they do not hide their designs and patents. All of them are available for use and application.

    The induction motor uses electromagnets (coils of wire wrapped around a ferrous It's a new type, and very hard to get right, but Tesla did it! the motor: The induction part of the technology's name has to do with the fact that.

    I feel this is overly vague, as i have worked on quite a few VDC rated brushed, mechanically commutated machines. Some "disk" tachometers have been made on this priciple, and would work backwards as motors. This argument can best be shown by observing a motor at stall. When maximum torque is required, especially at low speeds, the magnetic field strength B should be maximum — so that inverter and motor currents are maintained at their lowest possible values.

    Wally Rippel is a long-time proponent of electric vehicles. Wally has also worked for the Jet Propulsion Laboratory on electric vehicle battery research, among other projects. There are flat-heads, Hemis, straight, opposed, and V configurations. And on and on. One would have thought that, years ago, someone would have figured out which was best.

    That would have ended all the choices and thereafter only the one best engine type would be in production. There is no one best engine type, rather there are different types of engines to suit personal requirements, such as price and performance. This is also true for electric vehicle drives. Back when I had hair on my head and carried a slide rule , there were lead acid batteries, DC brush motors, and contactor controllers.

    Today, none of these remain including my hair. Lead has been replaced by lithium and DC by either DC brushless or induction. Contactors, meanwhile, have given way to modulating inverters. Without a good crystal ball, it is hard to predict the future. Each will have its loyal proponents and religious detractors. A Closer Look So what are these two technologies?

    How do they work? And what do they have in common? With brushless machines, the rotor includes two or more permanent magnets that generate a DC magnetic field as seen from the vantage point of the rotor. In turn, this magnetic field enters the stator core a core made up of thin, stacked laminations and interacts with currents flowing within the windings to produce a torque interaction between the rotor and stator. As the rotor rotates, it is necessary that the magnitude and polarity of the stator currents be continuously varied — and in just the right way - such that the torque remains constant and the conversion of electrical to mechanical energy is optimally efficient.

    The device that provides this current control is called an inverter. Without it, brushless motors are useless motors. A forerunner of the 3-phase induction motor was invented by Nikola Tesla sometime before Curiously, the stators for the 3-phase induction motor and the DC brushless motor are virtually identical. The essential difference between the two machines is with the rotor.

    Accordingly, an induced voltage exists across the shorted structure that is proportionate to this speed difference between the rotor and electrical frequency. In response to this voltage, currents are produced within the rotor conductors that are approximately proportionate to the voltage, hence the speed difference. Finally, these currents interact with the original magnetic field to produce forces — a component of which is the desired rotor torque. When a 3-phase induction motor is connected to utility type 3-phase power, torque is produced at the outset; the motor has the ability to start under load.

    No inverter is needed. The fact that induction motors are directly compatible with conventional utility power is the main reason for their success. In contrast, a brushless DC motor produces no starting torque when directly connected to fixed frequency utility power. While 3-phase induction motors have great utility, they also have some severe limitations.

    They cannot operate from DC; AC is a must. Shaft speed is proportionate to line frequency. Hence, when used with utility power, they are constant speed machines.

    Finally, when operated from utility power, they have limited starting torque and somewhat limited running peak torque capabilities, when compared to DC type machines. Add an inverter without any feedback control and it becomes possible to power an induction machine from a battery or other DC source; variable speed also becomes possible simply by adjusting the inverter frequency.
