Electric cars are often advertised as being more cost-effective and cost-effective to maintain, mainly because electric motors are much simpler than other motors. They can also have a significantly longer life than their gas counterparts. Consider the features of the Tesla electric motor.

Aim high

Tesla CEO Elon Musk said the ambitious goal is to keep Tesla's powertrains running for a million miles. It also means that they will almost never have to wear out.

On the way to this goal, the company has introduced several improved Tesla batteries, inverters and electric motors. Now the car manufacturer is introducing another updated device.

Recently, Tesla announced that it is launching a series of new S and Model X performance motor models. These motorsTesla can only be used on new vehicles that are built to date. The new equipment has an upgraded version of the Tesla rear engine.

Product range

In general, the automaker has managed to create three types of electric motors:

• main type engine, which provides for rear-wheel drive;
• smaller engine with front wheel drive - used for twin motor versions of Model S and Model X;
• larger rear drive version with engine performance.

After updating the performance specifications, Tesla has changed the number of its rear-wheel drive main engine. Subsequently, all versions affected by the update will be equipped with a Tesla electric motor, while all cars without it, the Model S P100D and Model X P100D, did not receive any performance improvements. The engine power is 416/362/302 hp. s.

The company didn't want to comment on the new drive unit, but it should have been a significant upgrade as it allows you to go from 0 to 60 mph in over 1 second.

Motor design features

Consider the characteristics of the electric motor "Tesla". Tesla actuators are built using a proprietary assembly process that includes:

• electric motor,
• power converter assembly,
• boxgears into a single multi-section housing.

Last year, it was revealed that Tesla was developing new power electronics from scratch instead of using out-of-the-shell components to drive the Model 3. The inverter architecture will allow for more than 300kW of Tesla's electric motor, bringing it closer to the performance of the Model S. But it's also implied that Tesla will likely update the Model S to further differentiate its increased performance from the less expensive Model 3. Tesla's car's electric motor performance provides a promise for its popularity.

Features of the Tesla production process

The first thing you notice on the Tesla Motors production floor is the robots. Eight feet tall, bright red robots that look like transformers snuggle up to each Model S sedan. Up to eight robots simultaneously work on a single Model S in a precise sequence, each car performing up to five tasks:

• welding,
• riveting,
• capturing and moving materials,
• metal bend,
• installing components.

Opinion of the director of the company

The Model X is a particularly difficult machine to assemble. Maybe the hardest car to build in the world. I’m not sure what will be more difficult,”admitted Elon Musk, founder of the billionaire Tesla company and itsCEO who also fills the same roles at SpaceX.

Musk wants to focus on building the best car in the world, and the $70,000 Model S is rightfully in line for the prize. It is an all-electric car and offers a week's drive on a single charge from any nationwide network of free solar charging stations.

This is the fastest four-door production car on the planet, being the safest car in its class. When he collides with the crash test car, the last one picked up for the test breaks.

Induction motor

Tesla's induction motor is a three-phase, four-pole motor. It consists of two main parts - stator and rotor.

The stator consists of three parts - the stator core, conductor and frame. The stator core is a group of steel rings that are insulated from each other and laminated together. These rings have slots inside the rings that the conductive wire will wrap around to form the stator coils.

To put it simply, there are three different types of conductors in a three-phase induction motor. They can be called phase 1, phase 2, and phase 3. Each type of wire is wrapped around slots on opposite sides of the inside of the stator core. Once the conductive wire is inside the stator core, the core is placed inside the frame.

How does an electric motor work?

The principle of operation of the electric motorTesla is like that. It starts with the battery in the car, which is connected to the engine. Electrical energy is supplied to the stator through the battery. The coils inside the stator (made of conductive wire) are located on opposite sides of the stator core and act like magnets. So when electrical power from a car battery is applied to the motor, the coils create rotating magnetic fields that pull the conductive rods outside the rotor along it. The spinning rotor is what creates the mechanical energy needed to turn the car's gears, which in turn turn the tires.

There is no alternator in an electric car. How is the battery charged? When there is no separate alternator, the motor in an electric vehicle acts as both a motor and a generator. This is one of the reasons why electric vehicles are so unique. As mentioned above, the battery drives the motor, which supplies power to the gears that turn the tires. This process occurs when the foot is on the accelerator - the rotor is pulled along the rotating magnetic field, demanding more torque. But what happens when the accelerator is released?

When the foot leaves the accelerator, the rotating magnetic field stops and the rotor starts to spin faster (as opposed to being pulled along the magnetic field). When the rotor spins faster than the rotating magnetic field in the stator, this action recharges the battery, acting as an alternator.

What does the three phases mean?

Based on the basic principles of Nikola Tesla as defined in his 1883 multi-phase induction motor, "three-phase" refers to currents of electrical energy that are supplied to the stator via a car's battery. This energy causes the conducting wire coils to behave like electromagnets. This ensures the operation of the electric motor.

As this technology continues to evolve, the performance of electric cars is starting to quickly catch up with and even outperform their gas-powered counterparts. While electric vehicles remain at some distance, the leaps made by companies like Tesla and Toyota have inspired hope that the future of transportation will no longer depend on fossil fuels.

Electric vehicles and the environment

From a large-scale perspective, there are several benefits to the growth of electric vehicles:

• noise pollution reduction because the noise, the electric motor is much more suppressed than the gas engine;
• electric motors do not require lubricants and maintenance like a gas engine, chemicals and oils.

Summarize

The electric motor has become especially highly valued over the past few years. Since most people understand and appreciate the impact of environmental pollutionenvironment on the climate, the demand for this vehicle, which can bring less harm to nature, is constantly increasing.

With this demand for growth and development, some of the world's greatest inventors improved the electric motor to perform better and be more efficient. Elon Musk is one of them. It brings the time when electric vehicles will be used everywhere. Then the ecology of the planet will be cleaner.
