How does an electric car without an engine work?
In the past two years, electric cars can be said to be a very popular thing. Major car parks are also developing new types of electric cars. As for the environmental protection of electric cars, everyone is also arguing about it. Let’s take a look at electric cars without engines. How does it work? Why is it so fast?
Then let's take a look at the working methods and output characteristics of electric motors and internal combustion engines. First of all, we must clarify a concept. For devices that output in a rotating manner, including electric motors and traditional internal combustion engines, a formula can be used: power = torque × speed. Therefore, within the same power level, the torque determines the acceleration performance of a car. By analyzing the relationship between the torque and the speed of the electric motor and the internal combustion engine, we can understand why the electric car accelerates so fast.
Motor working characteristics:
It can be seen that the motor can output the maximum starting torque when it just starts, and the torque tends to attenuate with the gradual increase of the speed. Therefore, when the motor reaches the rated power (rated speed and torque), the output torque is also No longer change. If you continue to increase the speed, the "back electromotive force" of the motor will produce current to offset its input current, so the torque will be further attenuated.
Working characteristics of internal combustion engine:
It can be seen that the biggest difference between an internal combustion engine and an electric motor is that the internal combustion engine can only output a small amount of torque at the start, and the torque gradually increases as the speed increases, and they are in a proportional relationship. And when the internal combustion engine, especially the internal combustion engine with turbocharging technology, the output torque will maintain a constant output in a certain speed range when the output torque rises to the maximum value, and the torque will decay only when the speed further increases.
Landscape lighting cable is a type of electrical cable used to connect outdoor lighting fixtures to a power source. It is designed to withstand exposure to the elements and is typically made of a durable, weather-resistant material such as PVC or polyethylene.
The cable is available in various gauges, with thicker gauges being able to handle higher wattages and longer distances. It is important to choose the appropriate gauge for the specific lighting system being installed.
Landscape lighting cable is typically buried underground to protect it from damage and to keep the installation looking neat and tidy. It is important to follow local codes and regulations when installing outdoor electrical wiring to ensure safety and compliance.
