Generally, a generator uses a permanent magnet or an electromagnet to derive electrical energy from magnetic energy of a magnet.

In addition, a general conventional motor (motor) is composed of a combination of a permanent magnet and an electromagnet, it is classified into AC and DC. DC magnet motors, which are commonly used in toys and small devices, are usually provided with hollow annular magnets in their outer cylinders, and armatures (amateurs) with coils wound in the hollows of the annular magnets provide a slight gap. It is wide open and a commutator is installed in one axis extension of the armature central axis. These commutators are divided into insulating plates according to the number of poles of the armature, and communicate with each armature coil. The commutator is assembled to the two brushes provided in the outer cylinder in an assembled state. When the + and-terminals of the power supply are connected to the two brushes in this way, current flows from the brush to the commutator and reaches the coil of the armature. First, the two-pole armature becomes an electromagnet of N and S, and the N, Adsorption with the S pole causes the pole to move in turn and begin rotation. Next, the commutator also rotates, and the commutator that has been in contact with the + terminal so far is in contact with the-terminal, and the rectifier that has been turned in contact with the + terminal changes the N and S poles in turn, thereby stimulating, adsorbing and repelling the field. Repeatedly, the armature continues to rotate and takes out rotation from the axis of the armature, thereby operating as a motor.

First, a cylindrical rotating shaft 130 and a rotor bearing shaft 140 connected to both end surfaces of the rotating shaft are installed at the centers of both supports 100. The rotor bearing shaft 140 is smaller than the radius of the rotating shaft, the bearing 142 is provided at the connection point with the rotating shaft 130. In addition, the first brush 150 and the second brush 152 are disposed to face each other at a predetermined position in contact with the side of the rotation axis.

On the other hand, the brush switch support is mounted on the rotating shaft to rotate together when the rotating shaft is rotated. In addition, the brush switch support is arranged a plurality of brush switches electrically connected to the rotating shaft spaced apart from each other by a predetermined distance. Accordingly, the first brush electrically connected to the battery 180 supplies power to the rotating shaft and the coil only during a time interval in contact with the rotating brush switch 160.

Next, the rotating plate 120 is attached to the side of the rotating shaft, at least one permanent magnet (110, 112) is attached to the edge of the circumferential surface of the rotating plate. At least one S-pole permanent magnet 110 is attached to the edge of one side of the rotating plate spaced apart from each other by a predetermined distance, and also the N-pole permanent magnet 112 is attached to the opposite surface of the rotating plate on which the S pole permanent magnets are installed. . Therefore, the rotor is composed of a pair of a rotating plate and a plurality of N-pole permanent magnets and S-pole permanent magnets, the N-pole permanent magnets and S-pole permanent magnets are opposed to each other at a predetermined position of the edge of the circumferential surface of the rotating plate Is mounted.

Here, the embodiment of the rotating plate, as shown in Figure 1, may be composed of one circular plate. In addition, another embodiment of the rotating plate may be composed of a plurality of separate rotating plate 120, as shown in FIG. In this case, the shape of the rotating plate may be made in a variety of rod shape, fan shape.

On the other hand, the motor according to another embodiment of the present invention by mounting at least one or more weights 190 on the edge of the circumferential surface of the rotating plate, it is possible to accelerate the movement of the rotating plate. Experimentally, it was found that when the generator was operated by mounting two 2.5 kg weights, the rotation speed of the generator was greatly increased.

In addition, the number of pairs of the N pole and S pole permanent magnet of the rotor attached to the motor according to the present invention is the same as the number of the brush switch, the brush switch is connected to the center of the rotating shaft and the permanent magnet of the rotor By arranging in a straight line, power can be supplied to the brush at the moment when the permanent magnet passes through the core core. As a result, power is supplied to the core core only at the moment when the permanent magnet of the rotor passes through the core core, so that the core core functions as an electromagnet.

In addition, the permanent magnet attached to the rotor of the electric motor according to the present invention should have a separation distance from the neighboring permanent magnet is greater than the width of the core core (170).

Hereinafter, the operation of the electric motor according to the present invention having the above-described configuration will be described in detail.

First, as the weight is moved on the upper part of the rotating plate of the motor, the rotating plate rotates while moving a certain distance by the potential energy of the weight. At this time, the larger the diameter of the rotating plate, the greater the rotational force. In addition, as the permanent magnet of the rotor is attracted to the core core by its magnetic field, the rotor is further accelerated and rotated.

The brush switch is mounted in a straight line formed by the permanent magnet of the rotor and the center of the rotating shaft to rotate together with the rotor. As a result, the moment the permanent magnet placed in line with the brush switch enters the core core, the brush switch is electrically connected to the brush, and a current flows in the coil wound around the core core so that the core core is electromagnet. Will act as. At this time, since the coil is wound to have the same polarity as the permanent magnet facing the core core, the core core becomes an electromagnet having the same pole as the permanent magnet facing. As a result, the permanent magnets introduced into the core core are pushed out of the core core by strong repulsion with the core core, and the permanent magnets fixed to both side plates in front of the core core are the polarity of the permanent magnet installed on the rotating plate pushed out by the repulsive force. By constructing the same pole on the front, it will bounce off the permanent magnet more powerfully. As this operation is repeated, the rotor continues to rotate.

Thus, the motor according to the present invention, by a brush switch and a brush having a unique configuration, by interlocking the current supply to the coil wound core core with the movement of the permanent magnet of the rotor can be properly controlled by In this case, the rotation of the rotor is accelerated, and power is supplied to the outside by the accelerated rotation of the rotor.

In addition, the electric motor according to the present invention, by mounting a weight having a predetermined weight or more to the rotating plate, and moving the weight up, the rotating plate is rotated by the potential energy of the weight, the rotation of the weight is The rotational force caused by the interaction between the electron and the core core is further accelerated. As a result, the efficiency of the electric motor can be further increased.
