Description

Motor with rotor and stator with improved structure {MOTOR CONSISTING OF ROTOR AND STATOR HAVING IMPROVED STRUCTURE}

The present invention relates to an electric motor comprising a rotor and a stator having an improved structure, wherein the position of the permanent magnet of the rotor is adjusted and the core iron core operating as the stator is controlled to control the operation of the rotor permanent magnet and core core. By increasing the rotation of the rotary shaft by the interaction of the present invention relates to an electric motor that can increase the efficiency of the energy derived therefrom.

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 a hollow ring magnet in the outer cylinder, and an armature (amateur) wound with a coil wound around the hollow part of the ring magnet. 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 commutator 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.

Accordingly, the present applicant intends to propose an electric motor that can achieve a high efficiency while relatively simple configuration by improving the structure of the permanent magnet and the stator.

It is an object of the present invention to provide an electric motor which can increase the efficiency of the energy induced therefrom by increasing the rotation of the rotating shaft by using the interaction of the rotor's permanent magnet with the stator core core.

It is a further object of the present invention to provide an electric motor which can increase the efficiency of the energy derived therefrom by further accelerating the rotation of the rotor using a weight of considerable weight.

Hereinafter, each component which comprises the electric motor which concerns on this invention is demonstrated concretely.

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 N pole permanent magnets 112 are attached to the opposite surface of the rotating plate on which the S-pole permanent magnets are installed. . Therefore, the rotor consists of a pair of rotating plate and a plurality of N pole permanent magnet and S pole permanent magnet, the N pole permanent magnet and S pole permanent magnet is mounted in a state opposite to each other at a predetermined position of the edge of the circumferential surface of the rotating plate do.

Here, one 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 400, as shown in FIG.

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 magnet introduced into the core iron core is pushed out of the core iron core by a strong repulsive force with the core iron core, and the rotor continues to rotate as this operation is repeated.
