As a new technology of new energy vehicles, hub motor has aroused people's heated discussion. Among them, the more controversial point is the endurance capacity of the wheel hub motor. When we buy a car, we first think about how far a car can run. This is also a question we are more concerned about. What are the factors that affect the endurance of the wheel motor? Let's follow the small series of global wind turbine to explore it!
1. Weight of the whole car
The weight of the whole vehicle is directly proportional to the rolling resistance of the vehicle. The greater the weight, the greater the load of the bearing and tire. The rolling resistance mainly comes from the friction produced by the bearing and the rolling resistance generated by the tire and the ground. It will continuously consume the electric energy of the wheel motor, which will not only affect the range, but also affect the performance of the extreme speed.
2. Hub motor volume
The volume of the hub motor also affects the range. In fact, the volume of the wheel motor is also directly proportional to the weight of the vehicle. The larger the volume, the greater the weight. If the volume of the hub motor is reduced, the weight of the whole vehicle can also be reduced. Under the condition that all other aspects remain unchanged, the whole vehicle becomes lighter and the driving range can be doubled.
3. Hub motor power
Wheel motor power is usually negatively correlated with the range, which affects the range. Hub motor is a tool to convert energy into power. On electric vehicle, it is equivalent to the engine of gasoline vehicle. Simply speaking, the power of motor is inversely proportional to the range of electric vehicle, because the work of motor is a process of non-stop power consumption. The efficiency of the motor depends on the daily driving habits of consumers.
4. Hub motor speed
In wheel motor, speed is an important technical parameter. Permanent magnet synchronous motor and asynchronous motor are usually used in the market. Permanent magnet synchronous motor uses permanent magnet to drive the rotor to move. Its advantages are high energy speed and less power consumption. However, the disadvantage is that the magnetic field of permanent magnet is limited, or it can not be increased unlimited, so its speed will be affected.
5. Wheel motor quality
The environment of wheel hub motor in the wheel is relatively bad, because it will involve the impact and damage of sand, mud and water in the vehicle driving, and even the possibility of wading in water, which has a great test on the quality and reliability of the motor. The quality is also related to the service life of the hub motor.
6. Hub motor maintenance
The later maintenance and maintenance of the wheel hub motor can also affect the driving range. As we mentioned earlier, the environment in which the wheel motor is located is harsh. If the wheel motor is not maintained and maintained in such an environment all the year round, the overall performance of the wheel hub motor will decline, so the maintenance and repair will also affect the range of driving range to some extent.
The above content is the answer to the factors that affect the endurance of the wheel motor. I believe that with the development of science and technology and the popularization of new energy vehicles, the endurance capacity and vehicle charging speed of the wheel motor will be improved
