Motpor device capable of reducing cogging torque
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.
