Abstract

PURPOSE:To obtain a small-sized and light-weight vibrating motor which has a very good efficiency and a large output torque and can be mass-produced easily by providing in the motor the wiring which supplies power to a brush from both positive and negative poles of a d.c. power supply and thereby generates a driving torque on a rotor and a weight which is mounted on a part of the outer part of the rotor. CONSTITUTION:On an outer surface of a magnetic field magnet 1, N and S magnetic poles of 90 deg. width are located. A mild steel cylinder 6 serves for both a magnetic path and an outer casing. The center of the bottom of a rotor 2 is secured on a lower end of a rotary shaft 7. As for a rotor 2, an armature coil 2a is well-orderedly wound in the square shape on an outer surface of the rotor 2 and is plastic-molded and a commutator 3 is buried in the bottom. In the central space of the armature coil 2a, a coil 11 which is an insulating wire of smaller diameter well-orderedly wound in the square shape is buried. After installing terminals 9a and 9b and a brush 4a on a disk 6a, the rotor 2 is press-fit in to a lower opening of the mild steel cylinder 6. When suppling power to the terminals 9a and 9b from a d.c. power supply, the rotor 2 is driven and then a three-phase commutator motor can be obtained.

The free end of the brush 4a, whose base is fixed to the + terminal 9a, is in sliding contact with the commutator surface. The brush 4b provided on the terminal 9b has the same structure but is not shown. The above-mentioned terminals 9a and 9b and the brushes 4a and 4 are provided on the disc 6a.
After mounting b, it is press-fitted into the lower opening of the mild steel cylinder 6. By supplying DC power to the terminals 9a and 9b, the rotor 2 becomes a three-phase commutator motor in which the rotor 2 is driven and rotated. FIG. 4 is a perspective view showing only the rotor 2. Only the armature coil 2a is shown in dotted lines. The armature coil 2a is wound in a square array. A coil 11 in which insulated wires having a small diameter are aligned and wound in a rectangular shape in the central space.
Is buried. The symbol 11a indicates a void in the central portion. Both terminals of the coil 11 are left open. Since the coil 11 is not present in the other armature coils, when the rotor 2 rotates, the coil 11 becomes an eccentrically provided weight (weight) and becomes an oscillating electric motor. Coil 1
In No. 1, when the rotor 2 rotates, the magnetic flux changes and an induced electromotive force is generated, but since both terminals are open, no current flows. Therefore, there is a characteristic that only the action and effect that vibration is generated without generation of reverse torque or Joule loss is obtained. A weight may be provided outside the field magnetic field. For example, vibration can be generated even if the iron piece 10 is fixed to a part of the outer circumference of the bottom surface of the rotor 2 as shown by a dotted line 10 in FIG.
