Patent attributes
A motor stator device with simple coil-winding structure is disclosed. The motor stator device includes an insulating base comprising an outer ring base, an inner ring base and a connection base, the outer ring base and the inner ring base alternatively forming outer ring openings, inner ring openings, outer ring sinks and inner ring pillars, the connection base being provided to be wound with a metal coil; a plurality of stator segments being positioned on the insulating base; and a plurality of segment connectors being positioned on the outer ring sinks between the insulating base and the stator segments and having a base part and an extension part opposite to the base part, the extension part being integrally extended from the base part and toward the motor rotor to get close to the inner ring pillar next to the motor rotor, so as to decrease the cogging torque.
