The electric bicycle is a mechatronic personal transportation tool which is provided with a motor, a controller, a storage battery, a rotating handle brake handle and other operating parts and a display instrument system on the basis of a common bicycle by taking the storage battery as an auxiliary energy source. The motors used by the electric bicycle are mostly high-efficiency rare earth permanent magnet motors, wherein the motors are mainly divided into a high-speed brush tooth and gear speed reduction motor, a low-speed brush motor and a low-speed brushless motor. The motor is a component for converting electric energy of the battery into mechanical energy and driving the electric wheel to rotate. There are many kinds of motors used in electric vehicles, including mechanical structures, rotation speed ranges, and energization forms. The following are common: brush geared hub motors, brush gearless hub motors, brushless geared hub motors, high-disk motors, side-mounted motors, and the like. Most electric bicycles use a hub type motor to directly drive the front wheel or the rear wheel to rotate. The hub motors are respectively matched with wheels with different wheel diameters according to different output speeds so as to drive the whole vehicle to run, and the speed can reach 20 km/h. Although the models of these electric vehicles are different from the installation positions of the batteries, the driving and control principles of these electric vehicles have common characteristics. Such electric bicycles are the mainstream of electric vehicle products.
