Claims

[Scope of utility model registration request]

A coil block in which a stator coil is held in a box-shaped casing forms a magnetic path for the magnetism generated by the stator coil, and a plurality of magnetic poles are arranged along the circumferential direction on one end surface in the axial direction of the stator coil. a rotor having a rotating shaft passing through a rotor plate which is arranged substantially parallel to the magnetic poles of the yoke and has a plurality of magnetic poles magnetized along the circumferential direction, and the yoke is inserted into a stator coil. a yoke body magnetically coupled to one end of the yoke tube and formed in a substantially U-shape along the outer periphery of the casing; a yoke body magnetically coupled to the other end of the yoke tube; and a yoke body magnetically coupled to the other end of the yoke tube; and a yoke plate which is magnetically coupled to the yoke plate and arranged to straddle between both legs of the yoke body, and a plurality of yoke plates are attached to either the tip of both legs of the yoke body or the side edge of the yoke plate. A locking pawl is provided protrudingly provided, and a plurality of locking grooves are formed on one of the two at positions corresponding to the locking pawls, and when the locking pawl is caulked and fixed to the locking groove, the yoke body and the yoke plate are connected. are joined together while holding the casing,
A small motor in which each corner of the casing is provided with a mounting hole that penetrates through the thickness of the casing.
