As the pole and S pole are magnetized in sequence, exerting an acting force on the rotor, the rotor rotating inside the stator rotates smoothly without vibration, and the rotation of the rotor is prevented because there is no collision with a specific cycle of AC power according to the change of polarity. It is done smoothly.

Description

Stator for bipolar motor

The present invention relates to a stator for a two-pole motor, and more particularly, a two-pole that suppresses vibration generated when driving the motor as much as possible, and at the same time has a uniform rotation and a uniform torque so that stable rotation and torque can be output. It relates to a stator for a motor.

In general, a motor converts electrical energy into a mechanical rotational motion, and is classified into a DC motor and an AC motor according to the type of power source.

AC motors are divided into three-phase alternating current and single-phase alternating current. Three-phase alternating current ranges from over 1kW to thousands of kW, and rarely over 10,000 kW. Used.

Although there are types of direct current and alternating current, in principle, they are the same, and the application of the electromagnetic induction phenomenon that electromagnetic force is generated in the direction perpendicular to the magnetic field by placing the conductor at a right angle with the magnetic field in the magnetic field, The electromagnetic force is proportional to the product of the magnetic field strength, the current strength and the conductor length.

Typically, a motor has a cylindrical stator core in a cylindrical frame and a frame inner diameter, and an armature winding is wound around the core.

A lead wire is shown at the end of the winding, and current and voltage are supplied from the lead wire.

In the rotor side configuration, magnets are attached to the shaft and the shaft outer diameter. Ball bearings are attached to both brackets and flanges.

In the conventional rotor, a four-pole is formed, and accordingly, in the case of a motor driven by winding a coil wound around the stator to match the four-pole shape of the rotor, power is applied so that the rotation is uneven when the rotor rotates. There is a problem that is rotated, and because the torque generated by the rotation is also nonuniform there is a problem that the characteristics appear bad.

When manufacturing a motor using the four-pole stator as described above and using it as a damper motor used to discharge the smell or smoke of food in a home or business office, the amount of air generated by discharging air was discharged. There is a problem that the action of the wind pressure to reach this predetermined distance is not continuously transmitted.

This means that the wind pressure generated by the motor reaches a predetermined distance, and in order to continuously discharge the wind pressure, the predetermined wind pressure and the air volume must be continuously generated. In the case of a four-pole motor, the wind pressure works weakly and only a large amount of wind is supplied. There is a problem that can not be properly discharged through the duct, in order to solve this problem there is a problem that the size of the stator has to be formed large to use a large torque generating motor.

As the size of the motor increases, there is a lack of installation space, and there is a door gem that does not facilitate the installation work for installing the motor and the duct.

In addition, there is a problem that the user has a complaint because the smell of food, smoke, etc. are not properly discharged, and the phenomenon is caused by the flow of water flowing back from the entrance and the middle of the duct.

In addition, the 4-pole motor has a problem that it is reluctant to use in a normal home because the sound driven is very loud.

The present invention for solving the above problems is to coil the coil wound in the winding groove of the stator in a parallel state in a series state in series state, so as to suppress the vibration generated when the motor is driven to the maximum smoothly with little vibration It is an object of the present invention to provide a stator for a two-pole motor in which an alternating current is applied to a coil wound with a coil so that no vibration occurs in a rotor rotating in the winding.

In addition, an object of the present invention is to provide a stator for a two-pole motor in which the rotation of the rotor rotated inside the stator by the application of power is uniform, and the torque generated according to the rotation is uniform, so that stable torque can be output.

In addition, when it is installed and used in the damper motor, the noise is less generated when the motor is driven, the vibration is less generated, and the wind pressure is properly generated, so that the smell of food or smoke is not settled at the beginning of the duct or the middle part. The purpose is to provide a stator for a two-pole motor that can be made smoothly.
