Motor with positioning component and electrical product thereof

A motor, which comprises a stator and a housing for accommodating the stator, wherein the housing comprises a housing wall and a housing bottom, the stator comprises a stator core and a resin component at least covering one side of the stator core facing the housing bottom,

• one side of the resin component facing the housing bottom has a concave component;
• one side of the housing bottom facing the resin component has a positioning component, and the positioning component is axially opposite to the concave component,
• wherein the positioning component is a through hole, and the through hole passes through the housing bottom,
• a periphery of the through hole on a axially lower surface of the housing bottom is an annular structure that is recessed relative to other parts of the axially lower surface of the housing bottom, and
• a surface smoothness of the annular structure is greater than a surface smoothness of the other parts of the axially lower surface of the housing bottom.
