Abstract

The invention relates to an electric motor which comprises an axis-tube component, a stator structure, a rotor structure and a magnetic body. The stator structure is arranged on the axis-tube component; the rotor structure has a rotating shaft and a magnetic component; the rotating shaft is arranged in the axis-tube component; the magnetic component is arranged correspondingly to the stator structure; the magnetic body is arranged between the rotor structure and the axis-tube component.

Description

technical field [0001] The invention relates to a motor, in particular to a motor which can effectively improve the electromagnetic effect. Background technique [0002] Motors are components that convert electrical energy into mechanical energy, and have been widely used in mechanical structures in daily life, such as fans, optical drives, or hard disk drives. Although there are many types of motors, the principle of their main application is the electromagnetic effect. [0003] Please refer to figure 1 As shown, a conventional motor 1 includes a rotating shaft 11 , a magnetic shell 12 , a magnetic ring 13 and a shaft tube 14 . Wherein, the rotating shaft 11 is connected to the magnetic conduction shell 12 and arranged in the shaft tube portion 14, and the magnetic ring 13 is connected to the inner wall of the magnetic conduction shell 12; in addition, the motor 1 has a coreless coil group (coreless coil) 15, its It is arranged between the shaft tube portion 14 and the m...
