Generator and rotary apparatus of motor

Abstract

The invention relates to a rotary device of a generator or electromotor that is capable of increasing the magnetic flux and preventing the loss of the magnetic flux, thereby enhancing the generation efficiency of the generator or motor. The rotary device of this invention includes: a stator having a hollow portion formed at the inside thereof and a plurality of slots formed to wind coils therearound, each of the plurality of slots being skewed at a predetermined angle; a rotor shaft formed of a nonmagnetic material; a cylindrical rotor body adapted to axially rotate together with the rotor shaft; a plurality of N-polar and S-polar permanent magnet groups insertedly coupled radially along the outside of the center portion of the rotor body in an alternating arrangement; a plurality of magnetic flux-increasing magnets insertedly coupled along the inside of the rotor body and arranged on the lines of magnetic force formed by the N-polar and S-polar permanent magnet groups, for increasing magnetic flux; and a rotor adapted to be rotatably inserted into the hollow portion of the stator.

Description

technical field [0001] The invention relates to a rotating device for a generator or an electric motor. Background technique [0002] As a prior art, in Korean Patent Registration No. 5,97,191 titled "Rotor of Generator and Motor" filed by the present applicant, the rotor has a plurality of flux increasing magnets for increasing magnetic flux, thereby Improve the working efficiency of generator or motor. [0003] However, in this prior art, the rotor is deflected at a given angle, thereby reducing cogging torque that causes vibration and noise in the generator and motor. [0004] In fact, in this case, due to the attractive or repulsive force between the upper permanent magnet and the lower permanent magnet, and the rotation of the rotor, it is not easy to form the required deflection, and it is not easy to maintain the originally designed deflection. [0005] Additionally, in conventional rotary devices where either the rotor or the stator, or both, are skewed, it is not ...

AI Technical Summary

Problems solved by technology

[0003] However, in this prior art, the rotor is deflected at a given angle, thereby reducing cogging torque that causes vibration and noise in the generator and motor

[0004] In fact, in this case, due to the attraction or repulsion between the upper permanent magnet and the lower permanent magnet, and the rotation of the rotor, it is not easy to form the required deflection, and it is not easy to maintain the originally designed deflection

[0005] Also, in conventional rotary devices where the rotor or stator, or both, are skewed, it is not easy to maintain the originally designed skew angle

The problem with this is that only the deflection of the original design cannot sufficiently reduce the cogging torque that causes noise and vibration

Therefore, according to this conventional practice, there is a problem in that the magnetic force is increased, but the cogging torque cannot be sufficiently reduced, thereby degrading the working efficiency.

[0010] As another prior art, in Korean Utility Model Patent Registration No. 0,182,495, the stator is annular, and when multiple stators are cut by means of a stamping process, there is a problem that the gap between adjacent stators The material and material of the interior of the annulus are unnecessarily consumed

[0011] In addition, since the coil is wound around the stator of the generator or motor, the stator and the rotor together cause electromagnetic induction, in this case, resonance may occur
