The development speed of Electric Tricycle in recent years

The motor controllers for Electric Tricycle have developed so fast in recent years that it is unimaginable, the operation is becoming more and more foolish, and the display is becoming more and more complicated. For example, the control of vehicle speed has been developed to cruise lock. In terms of driving, some have electric performance and power assist function at the same time. , the power assist can be performed or the size of the power assist can be determined.

China's Tricycle Motorcycle industry has formed a large-scale industrial group from small to large. Especially after entering the 21st century, the entire Tricycle Motorcycle manufacturer industry has shown a trend of rapid development. The development of the Tricycle Motorcycle industry has a strong The regionalism is manifested in production on the one hand and consumption in the other, and this is also a gradual process.
After buying a car, check whether the vehicle components are normal, whether the connecting parts are loose, whether the instrument display is normal, and whether the front and rear brakes are flexible. Pay attention to the tire pressure before each ride, and the pressure should be moderate. The lack of air pressure increases friction, and when riding hard, the power consumption is relatively large, and the speed of the vehicle must be reduced. Frequently check the flexibility of the brakes, whether the screws of the whole vehicle are loose, and the chain, flywheel, etc. need to be refueled. When braking, the governor should be loosened to avoid damage to the motor and other parts. When getting out of the car and pushing, the power should be turned off to prevent accidents caused by accidentally turning the speed control handle when the car starts suddenly.
Charge the battery immediately after picking up the car. Do not cover anything on the charger, pay attention to ventilation and waterproof; the charger contains high-voltage lines, do not disassemble it without authorization. The battery should also be filled with distilled water after a period of time to prevent the battery from drying up and affecting the battery life. The electric drawing car that has not been used for a long time should be started every 25 days or so, and run at a medium speed for about 20 minutes, otherwise the time is too long, and the electric drawing car will not start when the car is in use. During normal driving, you should always check whether the small hole on the battery cover is ventilated. If the small hole on the battery cover is blocked, the hydrogen and oxygen generated cannot be discharged, and the battery case will be broken when the electrolyte expands.
Types of motors Tricycle Motorcycle can be divided into three-wheeled motors according to the power device they choose-the structural form of the motor: friction transmission, central shaft sprocket transmission and hub drive. The technical difficulty lies in the difficulty in heat dissipation of the motor and the difficulty in lubrication of the transmission gear. In-wheel motors are divided into brushless and brushed. Brushless motors are mainly low-speed high-torque motors without brushes and transmission gears to avoid mechanical wear and tear. However, the large starting current impact, low overload capacity, complex structure of the control system, and high failure rate have affected the wide application of the motor.
