Description

Single-pole DC motor and brushless single-pole DC motor and single-pole DC linear motor {omitted}

The present invention relates to a direct current motor, and more particularly, to a direct current motor, more particularly, to a direct current motor in which a stator having a stator pole made of a single magnetic pole of a magnetic pole and an armature winding comprising a stator wound with a current flowing in the same direction orthogonally to a single magnetic field of the stator pole And a connecting ring, which is a cylindrical conductive metal connected to the armature so that the direction of the DC current supplied to the armature is not changed even if the armature is in any rotational position, is used for current supply and current discharging. And a brush for discharging the supplied DC current. When the DC current is supplied to the stator and the rotor at the time of supplying the external DC current, In the magnetic field, torque is generated by the Lorentz force according to the Fleming left-hand rule, The present invention relates to a direct current motor, in which a constant current is supplied to an armature in accordance with a rotation position of an armature in order to continuously obtain a torque in the same direction, To a DC motor.

In the prior art, when a direct current is made to flow in a magnetic field formed by an N pole and an S pole in such a manner that two conductors connected to a magnetic field perpendicularly to each other with current flowing in opposite directions can be rotated about its center axis, And receives the Lorentz force opposite to each other in the direction perpendicular to the flowing direction. At this time, when the direction of the current flowing in the wire is always the same, the wire stops rotating when the wire reaches 180 °. Therefore, the current direction should be reversed when the wire comes to the 180 ° position to continue the rotation, and the direct current supplied from the outside is switched from the fixed two brushes to the brush If the current is passed through the commutator composed of two semicircular conductors that rotate, the current direction changes every half turn in the conductor, so torque can be continuously obtained in the same direction and the rotation continues. A DC motor composed of a stator constituting the magnetic field and a stator made of a frame, an armature serving as a lead, and a rotor made up of a commutator and a brush has been developed and used, There is a limitation in the speeding up due to the problem of rectification which is required to periodically change the direction of the current supplied to the armature through the commutator in order to continuously obtain torque, and torque can not be generated at 360 ° around the rotor, It does not achieve speed.

It is an object of the present invention to provide a DC motor in which a magnetic field of a magnetic pole is formed into a single magnetic field and a torque in the same direction is continuously generated without changing the direction of a current supplied to the armature, do. Another object of the present invention is to provide a DC motor in which a magnetic field of a magnetic pole is formed as a single magnetic field and a torque in the same direction is continuously generated even if the armature is in any rotational position, And a method for manufacturing the same.

The single-pole-type DC motor according to the present invention comprises a stator of a stator of a DC motor composed of a stator and a rotor. The stator of the stator is composed of only N poles or S poles, It is composed of armature windings with conductors that make current flow in the same direction orthogonally to a single magnetic field and are connected electrically to the armature instead of the commutator and connected so that the direction of the DC current supplied to the armature does not change, The connecting ring, which is a cylindrical conductive metal, is fixed on the rotating shaft one by one for the current supply purpose and the current discharging purpose. The brush is used to supply the external DC current in contact with the connecting ring and to discharge the supplied DC current. When the external DC current is supplied, the current flows through the rotor and the stator, In by the armature current flows only in the same direction perpendicular to the magnetic field, the armature is generating a Lorentz force in the same direction and the torque (torque) generated by the Lorentz force generated it is operated.

○ The magnet for making the above-mentioned magnetic stimulus shall be a permanent magnet or an electromagnet or permanent magnet and a permanent magnet and electromagnet by winding an insulated conductor in an electromagnet or a permanent magnet in a circle as if making an electromagnet.

The armature winding of the armature is made of a conductor made of a ferromagnetic material such as iron or an alloy of such iron and a conductor metal so that the magnetic field of the system magnetic pole is strongly applied to the electric charge of the current flowing in the armature winding. It is possible to make an armature winding in which the magnetic field of the system stimulus is strongly applied to the charge flowing in each conductor constituting the armature winding.

In addition, the armature is formed by providing an armature winding on the permanent magnet surface which is opposite to the magnetic pole of the magnetic pole, and a magnetic field having a high magnetic flux density between the magnetic pole and the armature is formed, .

In addition, a permanent magnet, which is opposite to the stimulation of the magnetic stimulus, is formed on the permanent magnet surface by using a ferromagnetic material such as ferromagnetic iron or an alloy made of an alloy of such iron and a conductive metal to form an armature. And the strong magnetic field formed can be made stronger against the charge of the current flowing in the armature winding. - It is possible to make a strong magnetic field between the armature and the system magnetic pole by installing an iron core made of a ferromagnetic material at a constant interval where a magnetic field is formed between the conductors forming the armature winding. In addition, a method of installing an armature winding on the permanent magnet surface of the armature is to install a conductor so that a current flows perpendicularly to the magnetic field of the magnetic pole on the permanent magnet surface opposite to the magnetic pole of the system magnetic pole. The conductor is placed perpendicular to the magnetic field of the magnetic pole, and the magnetic field of the magnetic pole is perpendicular to the magnetic field of the magnetic pole. A method of installing a conductor is to make a single conductor surface of one armature winding to the end, make a second conductor surface in the reverse direction on the conductor surface of the formed one, and make a second conductor surface on the second conductor surface Make a third conductor face in the reverse direction, and in this way make one armature winding to the end ,

The magnetic field of the permanent magnetic pole is opposite to that of the permanent magnetic pole. The magnetic field of the magnetic pole is perpendicular to the magnetic field of the magnetic pole. The conductor is installed so that the electric current is passed through the permanent magnet. So that the way of installing such a conductor is wound around the thickness of one wound conductor face of the armature winding and again in this way to make one conductor face thickness wound on another armature winding, It is possible to form all of the armature windings and to connect each of them in series or in parallel or partly in series and partly in parallel or partly in parallel and the remaining parts in parallel to one another in series.

In this case, the conductor on the opposite side of the conductor provided on the side of the permanent magnet of the permanent magnet is opposite in the direction of current flow. The magnetic field of the permanent magnet is formed only between the permanent magnet of the armature and the magnet of the permanent magnet A Lorentz force is generated only by the current flowing through the conductor provided on the side of the permanent magnet of the permanent magnet when the armature current flows so that torque is generated, The Lorentz force that damps the torque is not generated by the current flowing in the opposite direction in the conductor provided on the opposite side of the magnetic pole.

It is also known that the armature winding is made of a conductor made of a ferromagnetic material such as iron or a conductor and a ferromagnetic material made of an alloy of iron and a conductive metal so that the magnetic field of the system magnetic pole is strongly applied to the electric charge flowing through the armature winding. It is also possible to use a higher electric conductivity by way of oxygen-free copper wire method, or to use it by using high-quality pure iron with high electrical conductivity or by using pure iron with high electrical conductivity It can be used by making the electric conductivity higher by oxygen-free copper wire method.

○ The conductors used for the field winding of the above-mentioned magnetic poles may also be made of a conductor made of an alloy of a conductor and a ferromagnetic material such as iron or iron and a conductor metal so as to form a stronger electromagnet. Iron having high conductivity can be used by using pure iron having a high electric conductivity or using pure iron with high electric conductivity by an oxygen free copper wire method.

○ In the system magnet of the stator making the single magnetic field and the armature part of the rotor generating the torque by generating the Lorentz force by the current flowing in the magnetic field orthogonally in the single magnetic field are interchanged to make a single magnetic field And the stator is provided with an armature for generating a Lorentz force by a current flowing in a single magnetic field in a direction perpendicular to the magnetic field so that a Lorentz force is generated by a current flowing in a single magnetic field in a single magnetic field when a DC current is supplied, The generated Lorentz force can produce a single-pole DC motor in which the rotor that produces a single magnetic field is rotated.

Of the single-pole DC motors that make up a single magnetic field in such a rotor portion, only permanent magnets are used in the rotor portion because brushes and connecting rings are unnecessary, and the brushes and the connecting rings are not used. There is no wear problem and becomes a brushless single-pole DC motor that can be used semi-permanently.

In the single-pole DC motor using the connecting ring and the brush except for the brushless single-pole DC motor, a single-pole DC motor can be divided into four types according to how the current is supplied to the field coil.

first. A decentralized single-pole DC motor with armature windings and field windings connected in parallel to the power source can be created.

second. A multi-pole single-pole DC motor with a field winding connected in series with a field winding connected in parallel with the armature winding and field winding is wound around one magnetic core.

third. It is possible to make a direct single-pole DC motor in which armature windings and field windings are connected in series.

fourth. A single excitation DC motor with armature windings and field windings connected to different power sources can be produced.

The armature of the single-pole DC motor consists of one or more armature windings. And the system magnet consists of one or more electromagnets or two or more permanent magnets.

The rotor of the brushless single-pole DC motor is constituted by two or more permanent magnets, and the stator is constituted by one or more armature windings.

The single-pole DC motor controls the rotation speed by increasing or decreasing the field current or increasing or decreasing the armature current.

When making the armature of the rotor into two or more armature windings, the currents flowing through each armature winding are caused to flow in parallel in series or in series, or partly in parallel and partly in parallel to each other .

When the stator poles of the stator are made of two or more field windings, the currents flowing in the respective field windings are caused to flow in parallel in series or in series or partly in parallel, .

When the armature is made of more than four armature windings and the current flows in series to each of the armature windings, the current flows in the order of the armature windings which are farthest from the armature windings supplied first, So that the torque generated by the shaft can be most effectively applied to rotate the shaft.

When the field stimulus is made of more than four field windings and the current flows in series to each field winding, it is possible to flow the current in the order of the field windings farthest from the field winding to which the current is supplied first

The rotor and the stator of the single-pole DC motor are cut in the radial direction to have the same structure as that developed in the shape of a flat plate so that the stator generates a linear driving force to the fixed portion of the linear motor and the rotor to the moving portion of the linear motor A single-pole DC linear motor can be produced.

The single-pole DC motor according to the present invention is characterized in that a single-pole DC motor of the present invention comprises a stator pole formed only by a single pole, an armature provided with a conductor through which current flows in the same direction orthogonally to the magnetic field of the stator pole, Since there is no problem of rectification, there is no limitation in speed-up, a perfect constant speed is realized, and a torque is generated at 360 ° around the rotor It is a DC motor that can be made.
