The invention relates to the technical field of electric scooters, and discloses a folding type three-form electric scooter which comprises a front scooter plate, a steering assembly is arranged on the inner wall of the front scooter plate, fixing grooves are formed in the outer walls of the two sides of the front scooter plate, sliding grooves are formed in the outer wall of the front scooter plate, and sliding blocks are slidably connected to the inner walls of the sliding grooves. A folding assembly is arranged on the outer wall of the sliding block, a rear vehicle plate is installed on the outer wall of the folding assembly, a foldable vehicle seat assembly is arranged on the inner wall of the rear vehicle plate, and foldable pedals are installed on the outer walls of the two sides of the front vehicle plate. According to the folding type three-form electric scooter, the highly-integrated driving chip DRV8301 is adopted, over-temperature and over-current protection can be achieved, PWM signals are given to the chip through the MCU to drive and control a three-phase bridge driving circuit of a brushless hub motor, precise control is achieved by combining an FOC algorithm, the design size of the circuit can be greatly reduced due to the fact that the chip is highly integrated, and therefore the design size of the circuit can be greatly reduced. The requirements of small vehicles are met.
