Proposed is a terminal coupling structure of an electric actuator in which a press rib is installed on the end of a contact plate such that a contact protrusion and a motor assembly terminal are more securely in contact with each other.

A fan motor of a cleaner capable of exhibiting a high output is provided. The fan motor includes a shroud disposed to cover a fan, a rotor fixed to a shaft, and a stator disposed opposite to the rotor in an axial direction with a predetermined gap therebetween. The stator includes a substrate on which a bearing is installed and a plurality of armatures disposed around the bearing. A coil is formed in such a way that a flat wire having a rectangular cross-section is bent to a short side thereof to be wound around an iron core.

A motor device and a method for producing same are provided. A connector storage unit (33d) and a substrate storage unit (33c) which are provided in a gear case (31) open in a direction (axial direction of output shaft) which intersects the axial direction of an armature shaft. As a result, when assembling a motor device (10), it is possible to store a connector member (60) and a control substrate (50) in the connector storage unit (33d) and the substrate storage unit (33c), which have comparatively large openings, by insertion therein from the same direction.
