<p>A balance controlling device of a rotator according to an embodiment of the present invention includes a rotator which is rotated around a rotary shaft and which includes a fixed protrusion groove on the outer circumference; a balance ring which includes a fixed protrusion inserted into the fixed protrusion groove on the inner circumference corresponding to the outer circumference of the rotator; and a balance weight which is formed on the balance ring and which controls rotation balance. Therefore, the present invention prevents damage of peripheral parts in comparison with a method of separating the fixed protrusion by external impact; and stably maintains the balance during driving by fixing the ring-shaped balance ring on the outer circumference of a hub. Additionally, the present invention firmly assembles the balance ring by inserting the fixed protrusion formed on the inner circumference of the balance ring into the outer circumference of the hub. Furthermore, the present invention can control the overall balance by using the balance weight formed on the outer circumference of the balance ring.</p> |
