を提供せんとするものである。The present invention involves wrapping a magnetic wire around the outer circumference of the circumferential coil of a cup-shaped rotor, concentrating the magnetic flux emitted from the permanent magnet that is the stator onto the magnetic wire, and using the magnetic wire as a magnetic flux path. By doing so, it is an object of the present invention to provide an external rotor type DC motor which increases the magnetic flux linkage with the coil, improves the torque of the cup-shaped rotor, has good electrical characteristics, and can be formed extremely simply.
以下図示の実施例に基づいて本考案を説明する。The present invention will be explained below based on the illustrated embodiments.

型直流モーターを構成する。In A, a permanent magnet a and a synthetic resin case 4 are integrally fixed by covering both end surfaces of the permanent magnet and the inner circumference of the center hole 5, and bearings 6.6' are installed at both ends above and below the center hole 5. A brush is placed and fixed on the end face of the permanent magnet facing the commutator, b
The cup-shaped rotor R is connected to the shaft 1 of the cup-shaped rotor R by a cylindrical fixed magnet whose one end is connected to the brush and whose other end is protruded from the outer surface of the synthetic resin case 4. 6,6
A cylindrical fixed magnet A is connected to b and is rotatably arranged, and a retaining ring 8 is attached to a protruding part from the bearing 6' of the shaft 1. and configure an external rotor type DC motor.

かもコスト安に製造できる実用的効果がある。Since the present invention has the above configuration, the magnetic flux emitted from the permanent magnet that is the stator is focused on the magnetic wire, and this magnetic wire is used as a magnetic flux path to increase the magnetic flux linkage with the coil, and the cup-shaped rotor An external rotor type DC motor with good electrical characteristics and improved torque has been obtained.Moreover, the cylindrical coil is reinforced with magnetic wire, so the open end of the cylindrical coil does not expand due to centrifugal force, and the characteristics are stable. This eliminates the need for man-hours for inserting the motor into the groove, and has the practical effect of making it possible to manufacture an external rotor type DC motor easily and at low cost.
