Description

Permanent Magnet Embedded 3-Step Armature DC Motor {.}

The present invention consists of an armature consisting of an iron core and a coil, and a permanent magnet in which the N and S poles are intersected in the circumferential direction, and three sets of armature iron cores are installed in close contact with one rotating shaft to rotate by suction or repulsion of the permanent magnet and electromagnet. As a DC motor, the power consumption is low and the output torque can be greatly improved. The armature core installed in three sets on the rotating shaft 17 is one group in FIG. 3, one group in FIG. 2 and one group in FIG. It is divided and cross-excited one by one to operate with repulsive suction force.

As shown, the permanent magnet 22 of FIG. 6 is magnetized in a circuit in the radial direction, and the iron core 13 of the armature portion is provided with the horizontal diagonals of FIGS. 2, 3, and 4 on the rotating shaft 17. .

In addition, the armature core 13 of FIG. 3 has armature cores of FIG. 2 and armature cores of FIG. 4 installed at opposite sides of the center line diagonals 27 of FIG. 2 and FIG. 4, and the armature of FIG. Located between the armature cores 13 of FIG. 4, in operation, the protrusions of FIG. 3 are installed at a slot, ie diagonally, between FIG. 2 and the armature protrusions of FIG.

The electric motor of the above structure is composed of three sets of armature iron cores 13, but in operation, the armature of Figs. 2, 3, and 4 alternates with the operation 2 group, and operates with suction repulsion force.

In addition, when power is applied to the armature unit, the armature is excited by the arming group 2, and the armature group that is not excited is dragged to the yoke iron piece 21 of FIG. 6, which is the maximum point of permanent magnetic force, as a simple iron core material. The yoke iron piece 21 between the permanent magnetic poles of FIG. 6 installed between the permanent magnets 22 is a method of operating at a high output while being sucked by the permanent magnetic poles opposite to the direction of rotation while being pushed by the repulsive force. It has a big influence and also greatly affects the speed of the motor.

Meanwhile, as shown in FIG. 7, the armature iron core 25 is installed on both sides of the rotor, and the armature cores 24 and 26 of FIGS. 2 and 4 are installed, and the armatures 24 and 26 are diagonally around the armature 25. (27) prevents caulking torque (horizontal vibration phenomenon) generated between the armature iron pole and the permanent magnet 22 generated during rotation.

In addition, the spacing between the armature protrusions and the armature protrusions 14 in the slots of FIGS. 5 and 2 according to the embodiment is a simple magnetic body and the spacing between the protrusions (at least one half of the face of the protrusions) is attracted to the maximum point of the permanent magnetic force. If not matched, the suction force on the permanent stimulus is lowered and the output torque and efficiency of the motor are reduced.

Therefore, in order to prevent the above problems, the spacing between the armature salient poles should be designed at least one half of the salient poles transversely of the opposing face and the permanent magnet opposing face.

In general, the embedded type or rotor-side permanent magnet DC motor cannot obtain high output efficiency compared to the input power consumption.

Therefore, the present invention is a method that is excellent in efficiency by generating a high magnet torque with a small input power consumption as a motor designed to complement the above problems.

In order to achieve this purpose, the permanent magnet 22 of FIG. 6 embedded in the cylindrical yoke main body has yoke iron pieces installed at the junction of the permanent magnet of FIG. 6 when the magnetic poles of N and S are opposed to each other. It is configured to arbitrarily adjust the inductance of the armature by the magnetic field of.

In addition, the battery is designed so that the magnetic force of the permanent magnet embedded in the stator side can be suctioned to the maximum by installing divided into three sets as shown in Figs. At this time, the gap between the armature salient poles 16 is a half of the gap between the armature salient poles 14 of FIG. In particular, the iron core core of the rotor is designed as an operation 2 group, and it is designed to minimize power consumption and generate high magnet torque by alternately repeating each other with the input power excitation group and the magnetic force attraction group of the permanent magnet. The point is part of the feature.

The present invention devised to achieve the above object is a permanent magnet embedded DC motor having a magnetic pole configured as a permanent magnet in a stator generating a magnetic field, and generates a magnetic torque in the rotor. When the iron core core is integrally installed on the rotating shaft 17 and the output torque is generated when the input power is excited, the yoke iron piece 21 between the fixed magnetic poles is designed to arbitrarily set the inductance of the armature.

In the present invention, the permanent magnet 22 is in close contact with the magnet torque generating point and the contact point between the magnetic poles of the permanent magnet embedded as the starting point of the armature 13 of FIG. The center point is set in two ways and each has its own operating characteristics.

The rotor core core is composed of three sets of 10 poles each, and during operation, Figure 3, which is the first group of the motion 2 group, is excited and repulsed by rotation. It is attracted by the magnetic force of the magnet to generate three-base rotation output. This operation principle alternately repeats the operation group 1 and group 2 of the armature.

In addition, the slot between the armature 16 of the armature of Figure 4 is an important point to increase the magnet torque to maintain the gap between the poles.

As described above, the present invention is a permanent magnet embedded DC motor of a type that obtains a much larger output than the input power consumption.
