Patent ID: 7038352

Claim:
A stator in a motor, comprising: a magnetism guiding part, being a hollow cylinder with an inner wall surface; a magnetizing part, having an upper electrode plate and a lower electrode plate, which are disposed to be opposite to each other, the upper electrode plate providing a first central through hole and the lower electrode providing a second central through hole being passed through with the magnetism guiding part; a coil seat with a third central through hole, being disposed between and enclosed by the upper electrode plate and the lower electrode plate, being wound with a coil and the third central through hole being passed through with the magnetism guiding part; a circuit board with a fourth central through hole, being disposed under the magnetizing part and the fourth central through hole being passed with the magnetism guiding part; and a support part, having a shape of disk to be joined to the magnetism guiding part; characterized in that the magnetism guiding part has a split opening straightly extending along the length thereof and a projection is provided at a specific spot of the circumferential edges of the first, second, third and fourth central through hole respectively to engage with the split opening and a stem extending upward to fit with the inner fitting surface of the magnetism guiding part for fitting with the inner wall of the magnetism guiding part.
