Abstract
During the assembly of a small motor, insulation is installed on the outer surface of a magnetic pole. An armature coil is wound so that the wire does not touch the corners of the magnetic pole. The wound coil does not loosen and sufficient insulation for the armature coil and magnetic pole gap can be secured when the assembly is completed. This allows as much ampere turn of the armature coil as possible to be obtained. Moreover, the thickness of the motor can be made flatter resulting in easier assembly of the flat motor's stator.
