External rotor motor stator core structure

The invention provides an external rotor motor stator core structure and relates to the motor field. At present, an external rotor motor punching sheet is formed usually through a one-piece punching mode, but the overall material utilization rate is low, production cost is high, motor production efficiency is low and winding is complex. The external rotor motor stator core structure comprises a stator core, an insulation skeleton and a winding. The stator core comprises an inner iron core and a plurality of separated external stator teeth arranged uniformly around the inner iron core. The external stator teeth and the inner iron core are connected through a connection structure to enable the inner iron core and the plurality of independent external stator teeth to be connected into a stator core sheet. According to the technical scheme, material utilization rate of the stator core punching sheet material is improved, winding production efficiency is improved, motor manufacture cost is reduced, motor vibration
