Claims

[Scope of utility model registration request]

A holder in which a commutator is arranged is fixed to the center of a rotor yoke made of a magnetic material plate, a coil is wound around each salient pole portion of the rotor yoke protruding from the commutator side, and a flat magnet fixed to the stator is fixed to the above. The coils are arranged facing each other, and the lead wires of adjacent coils are connected to each other.
A small DC motor in which each of the lead wires is connected to the tip of a riser extending from the commutator so as to be close to the coil side.
