Several types of electric bike motors
The electric bike motor is an important part of the electric bike with the longest warranty period, and there is no one. Because of its warranty period of three years. It directly affects the service life of the electric bike. It is one of the four major parts of the bike. You can divide electric bike motors into many types according to different ways. There are currently four common electric bike motors used in electric bike: brushed and geared hub electric bike motors, brushed and gearless hub electric bike motors, brushless and gearless hub electric bike motors, brushless and geared hub electric bike motors, etc.
1. Brief description of the basic situation of the electric bike motor
Among the four types of electric bike motors, the first three are the most common. Among these four types of electric bike motors, the best one is brushless and geared electric bike motors, follow by brushed and geared electric bike motors, and the third is brushless and gearless electric bike motors. The fourth, that is, the worst, is brushless and gearless electric bike motors.
2. Electric bike motors are classified according to speed.
Electric bikes are classified according to speed. Generally, there are two kinds of electric bike motors. High-speed electric bike motor: the speed is above 3000 rpm; low-speed electric bike motor: the speed is less than 300 rpm. High-speed electric bike motors have strong power and large torque. When you use for power driving, they have high efficiency and low energy consumption. Low-speed electric bike motors are the opposite.
However, if the high-speed electric bike motor used for electric bike runs at a speed of 3000 rpm, it is unimaginable. The speed can catch up with the car. If it runs under a heavy load, the rotor cannot rotate due to insufficient power, and the electric bike motor is easy to burn. So, use a reduction gear to reduce speed. The geared electric bike motors are all high-speed electric bike motors. Although you reduce the speed , the transformed pulling force (driving force) is obviously increased, and the load and climbing are very powerful. For low-speed electric bike motors, since the speed is inherently low, there is no need to reduce gears.
3. Electric bike motors are classified according to brushes.
Electric bike motors are divide into brush electric bike motors and brushless electric bike motors according to the presence or absence of brushes. The difference itself is not very big, but the brush electric bike motor needs to be replaced in time, because it is a vulnerable part. Brushless has a lower current and lower energy consumption than a brush. Therefore, the current mainstream market is brushless electric bike motor electric bicycles. The biggest advantage of the brushed electric bike motor is its simple structure, lower cost, and better starting and braking effects. In the low-speed state, the torque performance of the brush electric bike motor is excellent and the torque is greater.
However, its shortcomings are also obvious. The carbon brushes wear out quickly and requires frequent maintenance. In addition, you can compare with brushless electric bike motors, it has greater noise and lower efficiency. Finally, the environment is more affect it , easily demagnetized, and has a relatively short service life.
And brushless electric bike motors have many advantages, including strong anti-interference ability, low operating sound, and high efficiency. In addition, the service life of the brushless electric bike motor is longer, and there is basically no need for maintenance. However, brushless electric bike motors also have their own shortcomings, that is, the cost is higher, and when you demagnetize the electric bike motor, it consumes more electricity.
In conclusion, combining brushless and high-speed and low-speed, four types of electric bike motors appear.
