The present invention relates to an electric spinning top, and in particular, the first, second, and third motors of the first, second, and third bridges disposed equally along the circumferential direction from the upper and lower bodies are the same according to the power supply. Direction, the upper and lower main bodies can rotate, and assembly and operation may be such that power can be supplied to the first, second and third motors only when infrared light is received by the phototransistor installed on the upper main body.

In general, Fang refers to one of the traditional toys in Korea that sharply cuts off one end of a round piece of wood, taps it, or wraps and wraps the string around the body.

The spinning top is formed in a symmetrical structure with respect to the rotational axis so that it can be rotated without falling while being continuously rotated by rotational inertia by the initial rotational force.

Accordingly, it becomes interesting to allow the other side to rotate longer than the spinning top, and also makes the other's top not rotate by the impact, while also causing the other side to rotate. The tops also play in a way that allows them to spin for a long time.

In view of this point, a number of spinning tops developed in the related art apply a spinning top and rack and pinion structure in such a way that the rotational force can be transmitted to the top by winding a string to the top so that the rotational force can be transmitted to the top. There is a top.

In this method, since there is no separate energy supply, it is impossible to continuously supply energy, and thus, the rotational inertia force disappears and falls to one side.
