Like the Model 3, the indicator motor for the main wheels and rear wheels uses a motor similar to the second drive wheels, but the inductor motor rotor controls are made of cast. Aluminum, the first for Tesla.
But what exactly are synchronized and synchronous motors? Electric cars are the first basic property that distinguishes them from ICC cars. Here is how the standard four-stroke engine works
1. On the first stroke, the gasoline enters the chamber by opening the closed valve again.
2. On the second stroke, the cylinder moves up and the gas is compressed.
3. On the third stroke, the energy in the fuel is collected by turning it on. The explosion rotates the cylinder downwards and creates a circular motion. This can be compared to a bicycle, where it pushes the pedal down and moves the bicycle forward.
4. In the fourth and final stroke, the burning energy comes out.
This is basically a modern gasoline engine that was invented 150 years ago.
Now a simple electric motor works as follows
1. We take a wire and let it flow through it, so it creates its own magnetic field. It has become a magnet.
2. We place this magnetic spiral between two magnets, so that one side of the magnet is pushed up and down.
3. This causes the coil to rotate vertically. At that moment, we quickly change the pole.
4. The effect is a rotating motion and we find here a simple direct current motor in action.
The fastest comparison between electric motors and heat engines:
Heat motor Electric motor is an electric motor …
1-3 kW / kg 3-10 kW / kg 3x more powerful
0.4 kW / L 13.6 kW / L 40x less
5-30% efficient 93-96% efficient 3-20x more efficient
Multiple moving parts One mobile unit maintenance free
There are only three types of motors used in AVs today – the input motor, the fixed magnet motor and the synchronous motor.
Let’s start with a simple, familiar brush DC motor. This motor has a stator and rotor with an electric wire inside. When this coil is connected to the battery, it produces a direct current, the wire generates a magnetic field, which causes the coils to rotate in opposite directions with the permanent poles of the stator. To sustain this wave, the poles of the wires were changed.
AC induction motors (invented by Nicola Tesla) do not require permanent magnets. Instead, a magnetic field is produced by a current flowing through the housing or stator. If you now connect the stator to an alternating current, this means that the magnetic field in the stator also changes. If a three-phase AC input is used, a rotating magnetic field or RF is produced. The magnetic field in the stator causes voltage voltage and current in the rotor windings. That is why it is called an induction motor. This in turn leads the router to produce its own magnetic field, and this magnetic field causes the rotor to rotate to align itself with the stator magnetic field. The rotation follows this rotating magnetic field in the rotor without the need for travel.
Now, a brief description of a permanent magnet motor would be as follows: This eliminates losses and heat buildup in the rotor. Because of all of this, permanent magnet motors are the smallest and simplest electric motors you can buy now. The rotor is already magnetic, so it always resembles a rotating magnetic field. This is why permanent magnet motors are also classified as synchronous motors.
The parallel resistance engine seems to have been built recently and has achieved the best of both worlds. It has a metal rotor created in such a way that it naturally adjusts itself to the local magnetic field. This means that it does not need to generate its own electric field through induction waves, like an induction motor, which results in small losses. Lastly, it does not require permanent magnets, which makes it cheaper than a permanent magnet motor.
The Tesla Model Y power plant, combined with a 75 kWh lithium ion battery, uses a magnetic flux motor for constant performance. (EPA rated) 326 miles (525 km) for Long Range AWD (EPA-rated) and 244 miles (393 km) for standard range model (EPA rated). Tesla’s invention is made up of split magnets (four parts rather than the usual single solid magnet). According to Learn Engineering, it helps to reduce bubbles and reduce the risk of overheating magnets. Here is a very interesting explanation from the YouTube channel that explains the differences in technology: https://www.youtube.com/watch?v=esUb7Zy5Oio
As I mentioned in several previous articles, it is easy to understand why Tesla Model Y is ahead of the race with its fragmented technology and why any ICE vehicle manufacturer takes so much time, research and effort to get anywhere. Tesla is now in 2021.
