A motor stator structure includes a main body and multiple stopper plates. The main body has multiple magnetic poles and a shaft hole. The magnetic poles outward extend from the main body. Each magnetic pole has a free end outward extending from the main body. The shaft hole passes through the main body between two ends thereof. The stopper plates are respectively correspondingly assembled with the free ends of the magnetic poles. In the motor stator structure, the windings are more densely wound on the magnetic poles to enhance the magnetization efficiency.

Motor stator structure

A motor device capable of reducing cogging torque includes a stator assembly and a rotor assembly, which is movably disposed in the stator assembly. The rotor assembly provides a magnetic component. The stator assembly further includes an insulation frame part, a set of silicone steel sheets and a coil winding the insulation frame. A plurality of circular strip members are disposed at the circumferential side of the bottom of the stator assembly in a way of the respective circular strip member has an end thereof being attached to the bottom of the insulation frame part and another end thereof extending circumferentially to the sector shaped space. Further, the circular strip members space apart from each other without contacting the silicone steel sheets.

Motpor device capable of reducing cogging torque

A built-up stator assembly comprises a plurality of magnetic guide members and each of the magnetic guide members further comprises a frame arm, a rib and a magnetic pole part. The frame arm with two ends provides a joining part at the two ends respectively. The rib with an inner end extends inward from the frame arm and is wound with a coil. The magnetic pole part is provided at the inner end. The stator assembly can be built up with the magnetic guide members by way of joining parts engaging with each other.

Built-up stator assembly

A bearing assembly with auxiliary magnetism comprises a shaft, a fan base and a bearing. The fan base provides a hollow shaft seat with a receiving space to accommodate the shaft. The bearing fits with the shaft for supporting the shaft. A magnetic part surrounds the shaft to attract the shaft such that the fan blade hub can be fixed at a specific position.

Bearing with auxiliary magnetism

A stator device in a motor includes a magnetism guiding part, a magnetizing part, a coil seat, a circuit board and a support part. 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 central through holes of the magnetizing part, the coil seat and the circuit board respectively to engage with the split opening. A stem extends upward from the support part to fit with the inner wall surface of the magnetism guiding part.
