Description
The present invention relates to a motor for a linear compressor. More specifically, the present invention relates to an outer stator constituting the linear compressor motor, an inner stator, and features according to the shape and shape of the outer and inner surfaces of the mover.
A motor is a device that obtains rotational power by converting electrical energy into mechanical energy. Such a motor is classified into an AC motor and a DC motor according to the type of power applied thereto. Generally, a motor is an air conditioner or a refrigerator. It is widely used for driving home appliances.
Such a motor includes a stator (a stator) and a rotor (rotor or armature, hereinafter a rotor), and a rotor is formed by a rotating magnetic field generated when current flows through the coil of the stator. It operates on the principle of generating a torque in the rotation, by using the torque that the rotor rotates by the torque as the rotational power.
Among them, the linear motor is a deformation of the magnetic field of a motor having a three-dimensional structure into a flat plate shape, and this flat-shaped mover is also placed on the upper side of the flat stator and moves linearly according to the change in the magnetic field of the stator. to be.
In recent years, the stator has a cylindrical shape having an inner stator and an outer stator, and a magnet coil for generating an induction magnet is wound and mounted on either of the inner stator and the outer stator. A compressor linear motor has been introduced in which a magnet is placed between the inner stator and the outer stator and the magnet is arranged so that the polarity of the magnet is arranged in the axial direction of the stator.
Representatively, Korean Patent No. 10-0793804 discloses a structure of a linear motor in which a stator has a cylindrical inner stator and an outer stator, and a magnet coil is wound around a bobbin and then wrapped around its outer surface with an injection molding.
In the case of such a linear motor, a magnet coil is wound around the outer circumferential surface of the bobbin of the outer stator to generate induction magnetism. Then, the core is fixed by molding using an injection mold to form the outer shape.
The mover of the linear motor is composed of a cylindrical body portion and a top portion, and a plurality of magnets are radially coupled to the outer circumferential surface of the body portion.
The outer and inner surfaces of the outer stator, inner stator, and mover constituting the conventional linear motor are formed in a cylindrical shape. Therefore, a separate process for processing the inner and outer surfaces in a circular process is required in the manufacturing process, and also required for precise processing in order to maintain accurate voids, resulting in a loss of time and cost.
An object of this embodiment is for a linear compressor having a polygonal structure in which the inner surface shape of the outer stator of the linear compressor motor, the outer surface shape of the inner stator, and the outer surface shape of the mover interposed in the gap formed between the outer stator and the inner stator are polygonal. Is to provide a motor.
In the linear compressor motor according to the present invention for achieving the above object, in a linear motor comprising a stator composed of an outer stator and an inner stator, and a mover located in a gap formed between the outer stator and the inner stator. ;
The outer surface of the inner stator is provided with a polygon, the hollow portion of the outer stator is characterized in that it has a shape corresponding to the shape of the outer surface of the inner stator.
The mover includes a body attached to a magnet to form a magnetic field, and a body part positioned in the gap, and a top formed on one side of the body part to transmit a force in one direction. And a shape corresponding to the shape of the outer surface of the inner stator.
And, the outer surface of the inner stator is characterized in that it is provided in the shape of a regular polygon.
And, the inner stator is characterized in that it is molded into a powder core.
In addition, the core of the outer stator forming the outer stator is characterized in that it is provided only by the punching operation and the lamination operation in the mold.
And, the movable portion is characterized in that it is provided only by attachment of the magnet to the outer surface of the polygon.
According to this proposed embodiment, when the linear compressor motor having the polygonal shape and structure as described above is eliminated, the process required to process the circular shape in the manufacturing process is eliminated, thereby reducing the time and cost required for the linear compressor motor. In addition, it is easy to maintain a constant void, and thus has an advantageous effect on the electrical performance and noise, etc., and the shape can be changed as needed, which also has an advantageous advantage in space utilization.
