The principle and structure of electric toy cars are not complex. It can be considered that it is composed of a set of motor drive mechanisms based on the model car. The battery supplies power to the motor through the controller.
The motor is installed on the rear wheel, and the rotation of the motor drives the vehicle. The controller of the toy car is connected to the speed control throttle, and a power sensor is installed on the central shaft of the engine. Turning the speed control handle allows the controller to detect different voltage values. The controller can simulate and adjust the voltage transmitted to the motor based on the voltage value, thereby controlling the speed of the motor.
