Abstract: A three-phase motor structure includes a sectional stator, a winding set, a circuit board and an inner rotor. The sectional stator includes a detachable pole set which has a plurality of pole teeth. Before being assembled, the winding set is wound on the pole pins of the detachable pole set. The circuit board is mounted on the sectional stator and electrically connects with the winding set. The inner rotor extends through the sectional stator when assembled.

Abstract: A motor stator automatically assembling system includes a feeding unit, a wire-winding unit, a first conveyer unit, a second conveyer unit, a first assembly unit and a second assembly unit. The feeding unit is operated to feed a plurality of insulation members. The insulation members are arranged on the first conveyer unit to be conveyed to the wire-winding unit. The wire-winding unit is operated to wind wires on the insulation members to form a plurality of wire-wound insulation members. The wire-wound insulation members are arranged on the second conveyer unit to be conveyed to the first assembly unit. The first assembly unit is operated to insert pole teeth into the wire-wound insulation members to form a plurality of compact pole tooth sets. The second assembly unit is operated to combine the compact pole tooth sets with a stator ring frame to form an assembled motor stator.
