A better electric wheelchair is made of very good materials. Electric wheelchairs are now divided into aluminum alloy and steel tube. Maybe everyone’s idea still exists in the electric wheelchair that can be made when the aluminum alloy is broken. In fact, the electric wheelchair made of high-strength aluminum alloy is not lower than the hardness of steel pipe, and it is light and beautiful.
Controller:
The controller is the subject of an electric wheelchair. If it is described by human beings, it is human heart. Without it, your electric wheelchair cannot move. At present, the controllers are divided into domestic controllers and imported controllers. According to the current general price, the price of domestic controllers is generally not very high, and the price is generally controlled at around 7,000. In contrast, the price of imported controllers is obviously different. Generally, the price of imported controllers is about 10,000 yuan, which is a bit too high for ordinary people.
Motor:
The motor is the key part of the electric wheelchair. The motor is the gravity power drive part of the electric wheelchair. At present, there are mainly two types of brush motors (high-speed and low-speed) and brushless motors in China. The brushed low-speed motor has a larger current and weaker performance when starting and climbing; the brushed high-speed motor has good wear resistance and reasonable design, which effectively reduces the maintenance cost of the electric wheelchair. As my country stipulates that electric bicycles and electric wheelchairs are non-motorized vehicles, and the speed of brushless motors is above 20 km/h, they are not used.
Battery:
The battery is even more important to the electric wheelchair. The quality of the battery determines the driving range of the electric wheelchair and its safety. Electric wheelchairs on the market mainly use lead-acid batteries and lithium batteries. Lead-acid batteries are safer, but the capacity is relatively small. Lithium batteries have a relatively large capacity and light weight, which is relatively inferior in safety.
