Abstract
An inner-rotor-type motor includes four outer surface portions flush or substantially flush with the motor outer surface of the core-back portion provided in the frame portion of each of the two insulating members of the insulator to secure electrical insulation between the stator core and the coil. The outer surface portions of the frame portion of each of the insulating members are inserted between the leg portions of four corners of each of the cover members attached to the axial opposite sides of the stator core. In this state, the cover members are attached to the stator core. The inner-rotor-type motor makes it possible to easily and cost-effectively manufacture a cover member without impairing the dust-proofness of the interior of the motor and greatly improves ease of assembly.
