Field of the Invention The present invention relates to a motor device, and more particularly to a motor device that uses a metal coil to energize a magnetic field to drive rotation. [Previous Art] Referring to FIG. 1 , a general motor device 1 includes a rotor 11 , a stator 12 ′ and a base 13 . The rotor 11 includes a rotating shell m and a rotating shaft 112 fixed to the inner center of the rotating shell 111 . And a ring-shaped magnet 113 disposed on the inner circumference φ of the rotating shell 111, the stator 12 includes a circuit board 120 disposed on the base 13, and a plurality of sheets are disposed on the circuit board 12〇 and stacked on each other The steel sheet 122, and a plurality of coils ι21 wound around the silicon steel sheet 122, the base 13 includes a shaft tube 131, and a bearing 132 for the shaft 112 to be disposed and disposed in the shaft tube 131. With the above design, after the circuit board 12 is energized via the external power source, the silicon steel sheet 122 and the coil 121 are energized, thereby causing the ring magnet 113 to collide with the magnetic force of the silicon steel sheet 122 and the coil 121. Rotation e However, if the volume of the silicon steel sheet 122 and the coil 121 is reduced, the magnetic repulsion force generated by the energization excitation is generally lowered, thereby affecting the speed at which the ring magnet 113 rotates. Therefore, the silicon steel sheet 122 is affected. The coil 121 needs to occupy a certain volume to generate a magnetic repulsive force sufficient to maintain the rotation speed of the rotor n, and the thickness of the motor device 1 is limited.

The effect of the two hairmoons is that the first and second (four) pieces on the magnet ring are rotated by the magnetic repulsion by energizing the first coil set on the circuit board. The rotation of the rotating member not only simplifies the internal energizing of the components, but also reduces the occupation between the silicon steel sheet and the magnet ring, which is advantageous for the thinning operation of the motor.

The member 54 is well known to those of ordinary skill in the art, and its detailed components and actions will not be described again. With the above design, when the circuit board 51 is energized by the external power source, the first and second coil groups 52 and 53 can be energized to generate different parent magnetic fields, and the first and second steels are respectively generated. The sheets 43, 44 are placed on the magnet ring 42 to have two opposite magnetic directions. Therefore, the first and second steel sheets 43, 44 are magnetically mutually exclusive with the first and second coil groups U and 53 respectively. Rotation is caused to rotate the rotating member 41 and the magnet ring. Since the first and second coil groups 52, 53 are disposed on the circuit board ,, the wire mesh 121 is twisted for the prior art of Fig. 1. The space occupied by the steel sheet 200950275 ❹ 122 can be effectively reduced, and the first and second steel sheets 4_3, 44 are sheet-like structures having a relatively thin thickness, compared to the stone of the prior art of Fig. 1. The steel sheet 122 is composed of a plurality of laminated sheets, and it is obvious that the thickness can be effectively reduced. Further, the ring-shaped magnet 113 of the prior art of FIG. 1 must be coupled with the Shishigang month 122 and the coil 121 to sense The thickness is greater than the sum of both the Shishigang sheet and the coil 121, and The embodiment is because the first, coil group 52, 53 and the first, second, #43, and 44 are both extremely thin sheet structures, and the magnet ring 42 is again subjected to the first and second stone The sheet 43 44 is sandwiched, so the magnet ring 42 can also effectively reduce the thickness. Therefore, the first and second coil groups 52, 53, the first, the second stone, the 43, 44, and the magnet in the present embodiment The ring 42 can reduce the thickness, so that the motor device 2 can be considerably advantageous for the thinning operation during the manufacturing process. In addition, since the circuit board 51 is abutted against the fixing member 313 of the supporting member 312 In the case of the 丨Β3, the pad member 314 is made of a plastic material, and the texture thereof is relatively soft', which absorbs the vibration generated when the rotor unit 4 rotates, thereby improving the motor degree. Stabilizing the above-mentioned 'the far-reaching device 9 m of the present invention, the illegal device 2' is electrically excited by the first and second coil sets 52, 53 m άΊ μ Μ - h which are laid on the circuit board 51. The first and first stone sheets 43 and 44 on the magnet are coupled to drive the rotating member 41 and the magnet ring 42 due to their magnetic repulsion. Turning to the assisting technology, the motor device 2 not only simplifies the internal power-on excitation but also simplifies the use of the steel sheet and the magnet ring, so that it can achieve the object of the present invention. 10 200950275 The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the invention, that is, the simple equivalent change of the scope of the invention and the description of the invention.
