The principle of the controller is as follows: it generates rectangular pulses and adjusts the speed of the motor through the duty cycle of the pulses. The rotor of the motor is a coil and the stator is a permanent magnet. The pulse wave is rectified by the inductance of the coil and becomes a stable direct current. The duty cycle of the pulse is controlled by the speed control button on the handle.
There is a light-emitting diode and a receiving diode inside the speed control button, with a transparent range in the middle, a dividing wall from light to dark, so that the signal changes from weak to strong, and is sent to the controller to generate rectangular pulses with different duty cycles.
The car has a steering system, power display system, lighting system, manual emergency system, hand braking system and stepless speed adjustment function. The driving device is driven by a front-wheel motor and is easy to operate; it is equipped with front and rear turn signals and rearview mirrors to make driving safer; it is equipped with two sets of battery cough switches for use, with a long cruising range; the electronic controller uses a microcomputer chip control circuit for adjustment , wide speed range, reliable performance, conducive to protecting the motor and battery, beautiful overall appearance, advanced performance, green and environmentally friendly. Environmentally friendly transportation.
It is recommended to protect the electric wheelchair from rain and moisture when storing it outdoors. Impacts, collisions and falls should be avoided during driving, transportation and storage; tires must be checked before use, and the electromagnetic brake of the motor is effective. Check whether vehicle parts are loose or unstable; do not stand on the pedals to prevent the electric wheelchair from losing balance and causing personal injury; check whether the battery power is sufficient before going out; check whether the automatic and manual brakes are effective before going uphill and downhill; if If the electric wheelchair is not used for an extended period of time, the battery should be removed and stored.
The battery should be fully charged every other month and also requires regular maintenance. Store in a cool, dry place, avoid placing heavy objects on top, and wipe the surface frequently. Check every fastener, tire, motor, and electromagnetic brake every month and add lubricating oil; when the road conditions are bad, try to choose manual assistance; when the reversing speed is not easy to be too fast, try to choose first gear; fasten your seat belt; Electric wheelchairs are not suitable for driving on wet green slopes.
