With the increasing ageing of society and age, more and more older adults become inconvenienced with their legs, not to mention the disabled. Compared to traditional manual wheelchairs, electric wheelchairs are more convenient and autonomous, thus becoming a standard mobility tool used by them. To purchase an excellent electric wheelchair, we must first clarify the structural composition of the electric wheelchair, that is, the five major components of the electric wheelchair (controller, motor, battery, electromagnetic brake and frame), as a professional power wheelchair manufacturer, the following we follow these five major components are explained in detail.

(1) Controller. The controller is the "heart" of the electric wheelchair. Due to the massive localization of imported controllers, the stability of most domestic controllers has been dramatically improved, and the advantages of imported controllers over domestic controllers have yet to be apparent.

(2) motor (including gearbox). Electric wheelchair motors are divided into brush motors and brushless motors. Both types of engines have their advantages and disadvantages, brush motors need regular replacement of carbon brushes, but driving inertia is minimal; brushless motors do not require maintenance, but the speed has very slight inertia. The quality of the engine depends on the magnetic cylinder material and coil material, so the price difference is there.

When choosing a power wheelchair, you can compare and observe the motor's artistry, power, noise and other factors. The gearbox is matched with the engine, and the gearbox is good or bad depending on the metal material and sealing performance. Since gears in the gearbox bite and rub against each other, lubricating oil is needed, so filling the oil seal and the sealing ring is crucial.

(3) Battery. Batteries are divided into lithium batteries and lead-acid batteries. Lithium batteries are small, lightweight, have more charge and discharge cycles, and have a longer service life, but they are more expensive; lead-acid batteries are affordable but large and heavy, and the number of charges and discharge cycles is only about 300-500 times. Lithium battery electric wheelchair is lighter in weight, generally around 25 kg.

(4) Electromagnetic brake. An electromagnetic brake is an electric wheelchair essential to the safety of security. Many electric wheelchairs on the market remove the electromagnetic brake function to reduce costs. In contrast, the matching motor gearbox and other components that must be equipped with the configuration are reduced accordingly. Such electric wheelchairs are okay to drive on flat roads but will slip when driving on uphill or downhill sections. Determining whether a power wheelchair has an automatic brake function is very simple. When buying a power wheelchair, power off and push forward if you can slowly cause the electric wheelchair is not equipped with electromagnetic brakes, and vice versa.

(5) electric wheelchair frame. The difference between the frame is the material and the rationality of the structural design. Frame material is mainly divided into iron, steel, aluminium alloy and aerospace aluminium alloy (7 series aluminium alloy); aluminium alloy and aerospace aluminium alloy material frame lighter weight and compactness relative to other materials frame production process and different equipment, the cost of higher prices. Most consumers most easily ignore the appropriate form of electric wheelchair frame structure design. The same material wheelchair frame, the structure design is different, the ride comfort is extra, and the wheelchair life is also very different.

The above is about the composition of the electric wheelchair. If you need more detailed information, welcome to contact us!
