It is a top view showing the stator of a magnetically driven rotating device according to an embodiment, and Figure 4 is a bottom view showing a rotor of a magnetically driven rotating device according to an embodiment of the present invention.

The magnetically driven rotating device 100 according to an embodiment of the present invention includes a stator 110 including stator magnets 120a and 120b, and a rotor magnet forming a magnetic circuit with the stator magnets 120a and 120b. A rotor 130 including (140a) (140b), a control drive 150 for providing rotational force or braking force to the rotor 130, and an output unit 160 that produces power according to the rotation of the rotor 130. ) includes. The rotor 130 may rotate by magnetic interaction between the stator magnets 120a and 120b and the rotor magnets 140a and 140b. Rotor 130 may be accelerated or decelerated by control drive 150.

The stator 110 includes a fixed body 111, a plurality of stator base supports 112 supported by the fixed body 111 and spaced apart along the circumferential direction, and a stator magnet supported by the stator base supporter 112. Includes 120a)(120b).

The fixed body 111 may be made of a magnetic or non-magnetic material, but is preferably made of a non-magnetic material. The fixed body 111 may be fixedly installed to support a plurality of stator base supports 112 and a plurality of stator magnets 120a and 120b. The fixed body 111 may have various shapes.

The stator base supporter 112 is made of a magnetic material. The magnetic force lines of the magnetic circuit formed by the stator magnets 120a and 120b and the rotor magnets 140a and 140b may pass through the inside of the stator base supporter 112. As the stator base supporters 112 are spaced apart in the circumferential direction, the stator magnets 120a and 120b supported by one stator base supporter 112 are connected to the other stator magnets 120a supported by the other stator base supporter 112. A magnetic circuit independent of (120b) can be formed.

The plurality of stator magnets 120a and 120b are sequentially arranged along the circumferential direction, thereby sequentially applying attractive force to the rotor magnets 140a and 140b of the rotor 130. Accordingly, the rotor magnets 140a and 140b move along a circular rotation path P when the rotor 130 rotates.

As shown in Figures 3 and 5, a plurality of stator magnets (120a) (120b) are arranged spaced apart along the circumferential direction to form one unit stator magnet group (GU), and the unit stator magnet group (GU) includes a plurality of stator magnets (GU). The dogs are spaced apart along the circumferential direction.

The separation distance between the plurality of unit stator magnet groups (GU) spaced apart in the circumferential direction is preferably greater than the separation distance between the plurality of stator magnets 120a and 120b spaced apart in the circumferential direction within the unit stator magnet group (GU). The gap between two neighboring unit stator magnet groups (GU) may form a jump section (A3) in which the rotation speed of the rotor 130 is amplified. That is, when the rotor 130 rotates, the rotor magnets 140a and 140b moving along the rotation path P pass through the space between one unit stator magnet group GU and another unit stator magnet group GU. Movement speed can be amplified when doing so. A more detailed rotation process of the rotor 130 will be described later.

The unit stator magnet group (GU) includes a first group (GM1) and a second group (GM2) arranged in order along the circumferential direction. The stator magnets 120a and 120b constituting the first group GM1 may form an acceleration section A1 that increases the moving speed of the rotor magnets 140a and 140b. And the stator magnets 120a and 120b constituting the second group GM2 may form a holding section A2 that maintains the movement of the rotor magnets 140a and 140b. The maintenance section A2 is a section that reduces the resistance pulling the rotor magnets 140a and 140b in the retreat direction and maintains the forward movement speed of the rotor magnets 140a and 140b.

The stator magnets 120a and 120b forming the second group (GM2) are configured to pull the rotor magnets 140a and 140b with a smaller attractive force than the stator magnets 120a and 120b forming the first group GM1. You can. In this case, the stator magnets 120a and 120b of the second group (GM2) can pull the rotor magnets 140a and 140b in the forward direction with a relatively small force when the rotor magnets 140a and 140b approach. However, after the rotor 130 passes, the rotor magnets 140a and 140b can be pulled in the retreat direction with a relatively small force.

The attractive force applied to the rotor magnets 140a (140b) by the stator magnets (120a) (120b) located at the rear of the rotor magnets (140a) (140b) based on the moving direction of the rotor magnets (140a) (140b) is the rotor magnet. It acts as a resistance force that hinders the progress of (140a) (140b). The stator magnets 120a and 120b forming the second group (GM2) are rotor magnets when the rotor magnets 140a and 140b pass through the area of the second group (GM2) and move to another unit stator magnet group (GU). A relatively small resistance force can be applied to (140a) (140b). Accordingly, the rotor magnets 140a and 140b passing through the jump section A3 between the two unit stator magnet groups GU receive relatively less resistance from the unit stator magnet group GU disposed at the rear, It can move more stably toward the unit stator magnet group (GU) placed in the front. In this way, rotation of the rotor 130 can be maintained by magnetic interaction between the stator magnets 120a and 120b and the rotor magnets 140a and 140b.

In the drawing, the stator magnets 120a and 120b included in the unit stator magnet group (GU) are shown to be divided into a first group (GM1) and a second group (GM2), but one unit stator magnet group (GU) ) can be divided into a variety of groups, such as three or more groups.

As shown in FIG. 5, the stator magnets 120a and 120b include a first stator magnet action surface 121 of an arc shape and a second stator magnet action surface 122 of a planar shape, and the cross-sectional shape is fan-shaped. It consists of The magnetization direction of the stator magnets 120a and 120b may be perpendicular to the tangential direction of the rotation path (P) or may be arranged at an angle.

Here, the 'magnetization direction' refers to the direction indicated by the line connecting the strongest S-pole part of the permanent magnet to the strongest N-pole part. In the drawing, the magnetization direction is the arrow direction shown inside the stator magnets 120a and 120b and the rotor magnets 140a and 140b. In each stator magnet (120a) (120b), both end portions of the arrow indicating the magnetization direction may have a greater magnetic flux density than other portions.

The stator magnets 120a and 120b are arranged so that either the N pole or the S pole faces the rotor 130.

As shown in FIG. 5, the first stator magnet action surface 121 and the second stator magnet action surface 122 of the stator magnets 120a and 120b disposed in the acceleration section A1 are disposed along the circumferential direction. The order in which the first stator magnet action surface 121 and the second stator magnet action surface 122 of the stator magnets 120a and 120b disposed in the holding section A2 are arranged along the circumferential direction are different. That is, the stator magnets 120a and 120b constituting the first group (GM1) are arranged in the order of the second stator magnet action surface 122 and the first stator magnet action surface 121 based on the circumferential direction. do. On the other hand, the stator magnets 120a and 120b constituting the second group (GM2) are arranged in the order of the first stator magnet action surface 121 and the second stator magnet action surface 122 based on the circumferential direction. do.

The shape and arrangement of these stator magnets (120a) (120b) allow the rotor (130) to maintain continuous propulsion due to magnetic interaction between the stator magnets (120a) (120b) and the rotor magnets (140a) (140b) of the rotor (130). It is to obtain it. By varying the arrangement form of the stator magnets 120a and 120b constituting the first group GM1 and the arrangement form of the stator magnets 120a and 120b constituting the second group GM2, the second group GM2 ), the stator magnets 120a and 120b can minimize the resistance pulling the rotor magnets 140a and 140b in the retreat direction.

The shape and arrangement of the stator magnets 120a and 120b can be changed in various ways. For example, as the stator magnets 120a and 120b, permanent magnets having various shapes and various magnetization directions can be used as shown in FIG. 26.

1 to 3, the stator magnets 120a and 120b include a first stator magnet 120a and a second stator magnet 120b that are radially spaced apart from the rotation center axis of the rotor 130. can do. The first stator magnet 120a may be located relatively farther from the rotation center of the rotor 130 than the second stator magnet 120b. The polarity of the first stator magnet 120a facing the rotor 130 may be opposite to that of the second stator magnet 120b facing the rotor 130. For example, the first stator magnet 120a may be arranged so that its S pole faces the rotor 130, and the second stator magnet 120b may be arranged so that its N pole faces the rotor 130.

The number of first stator magnets 120a and second stator magnets 120b within one unit stator magnet group GU is the same. Within one unit stator magnet group (GU), a plurality of first stator magnets 120a and a plurality of second stator magnets 120b are arranged in pairs. The paired first stator magnet 120a and the second stator magnet 120b may be coupled to one stator base supporter 112 to form one stator magnet array AS. The first stator magnet 120a and the second stator magnet 120b constituting one stator magnet array (AS) form a magnetic circuit with a pair of rotor magnets 140a and 140b positioned to face them. You can.

The first stator magnet 120a and the second stator magnet 120b constituting one stator magnet array AS may be arranged to be offset from each other in the circumferential direction.

In the drawing, two stator magnets 120a and 120b are shown coupled to one stator base supporter 112, but the number of stator magnets coupled to one stator base supporter 112 can be varied. there is.

The distance at which the stator magnets 120a and 120b included in one unit stator magnet group GU are spaced apart in the circumferential direction may vary. In addition, the distance at which the stator magnets 120a and 120b included in the first group (GM1) are spaced apart in the circumferential direction, and the distance at which the stator magnets 120a and 120b included in the second group (GM2) are spaced apart in the circumferential direction. Distance may vary. Additionally, the length of each jump section A3 provided between the plurality of unit stator magnet groups GU may be the same or different.

Referring to FIGS. 1, 2, 4, and 5, the rotor 130 includes a rotating body 131 and a plurality of rotor base supports 132 supported by the rotating body 131 and spaced apart along the circumferential direction. and rotor magnets 140a and 140b supported on the rotor base supporter 132.

The rotating body 131 may be made of a magnetic or non-magnetic material, but is preferably made of a non-magnetic material. The rotating body 131 may rotate with the shaft 133 as the central axis of rotation. The rotating body 131 may have various shapes.

The rotor base supporter 132 is made of a magnetic material. The magnetic force lines of the magnetic circuit formed by the stator magnets 120a and 120b and the rotor magnets 140a and 140b may pass through the inside of the rotor base supporter 132. As the rotor base supports 132 are spaced apart in the circumferential direction, the rotor magnets 140a and 140b supported by one rotor base supporter 132 are connected to the other rotor magnets 140a supported by the other rotor base supporter 132. A magnetic circuit independent of (140b) can be formed.

The plurality of rotor magnets 140a and 140b are arranged to be spaced apart along the circumferential direction, so that they can sequentially interact with the stator magnets 120a and 120b continuously arranged in the circumferential direction. The rotor magnets 140a and 140b include an arc-shaped first rotor magnet action surface 141 and a planar second rotor magnet action surface 142, and have a fan-shaped cross-section. The magnetization direction of the rotor magnets 140a and 140b may be perpendicular or inclined to the tangential direction of the rotation path P. In the drawing, the magnetization direction is the arrow direction shown inside the rotor magnets 140a and 140b. In each rotor magnet (140a) (140b), both end portions of the arrow indicating the magnetization direction may have a greater magnetic flux density than other portions.

The shape of the rotor magnets 140a and 140b can be changed in various ways. For example, as the rotor magnets 140a and 140b, permanent magnets having various shapes and various magnetization directions can be used as shown in FIG. 26.

The rotor magnets 140a and 140b are arranged so that one of the N and S poles faces the stator magnets 120a and 120b. Specifically, the rotor magnets 140a and 140b have one of the N and S poles facing the stator magnets 120a and 120b so that an attractive force can occur between them. arranged to do so.

As shown in FIG. 2, the rotor magnets 140a and 140b may include a first rotor magnet 140a and a second rotor magnet 140b that are radially spaced apart from the rotation center axis of the rotor 130. . The first rotor magnet 140a may be disposed relatively farther from the rotation center of the rotor 130 than the second rotor magnet 140b. The first rotor magnet 140a may be arranged with its N pole facing the first stator magnet 120a, and the second rotor magnet 140b may be arranged with its S pole facing the second stator magnet 120b. The first rotor magnet 140a and the second rotor magnet 140b supported by one rotor base supporter 132 may form one rotor magnet array AR. The first rotor magnet 140a and the second rotor magnet 140b constituting one rotor magnet array (AR) can form a magnetic circuit with a pair of stator magnets 120a and 120b arranged to face each other. there is.

The first rotor magnet 140a and the second rotor magnet 140b constituting one rotor magnet array AR may be arranged to be offset from each other in the circumferential direction.

In the drawing, one rotor magnet array (AR) is shown as consisting of two rotor magnets 140a and 140b, but the number of rotor magnets constituting one rotor magnet array (AR) can be varied. there is.

The rotor 130 may rotate by magnetic interaction between the stator magnets 120a and 120b and the rotor magnets 140a and 140b. As shown in FIG. 2, when the rotor magnets 140a and 140b are positioned to face the stator magnets 120a and 120b, the first stator magnet 120a, the second stator magnet 120b, and the first stator magnet 120a The rotor magnet 140a and the second rotor magnet 140b form a magnetic circuit. Accordingly, the rotor 130 can rotate by obtaining kinetic energy due to the attractive force applied by the stator 110.

Intuitively, the rotor 130 may be expected to stop by receiving attractive force from the stator magnets 120a and 120b, but the rotor magnets 140a and 140b of the rotor 130 are arranged sequentially along the circumferential direction. By sequentially forming a magnetic circuit with the stator magnets 120a and 120b, the rotor 130 can maintain rotation.

Referring to FIG. 5, the magnetic force between the rotor magnets 140a and 140b and the stator magnets 120a and 120b varies depending on the positions of the rotor magnets 140a and 140b. The rotor magnets 140a and 140b receive attraction from the closest stator magnets 120a and 120b, but also receive attraction from other stator magnets 120a and 120b arranged along the circumferential direction. Accordingly, the rotor magnets 140a and 140b can move by obtaining a moving force without being stopped by the attractive force of the specific stator magnets 120a and 120b.

The rotor magnets 140a and 140b moving along the rotation path P receive a relatively large magnetic force from the stator 110 in the acceleration section A1 and move, and are moved by receiving a relatively large magnetic force from the stator 110 in the maintenance section A2. It can move by receiving a relatively small amount of magnetic force. The rotor magnets 140a and 140b receive a relatively small amount of kinetic energy from the stator 110 in the holding section A2, but after passing the holding section A2, the stator magnets in the holding section A2 ( Relatively small resistance is received from 120a) (120b). The rotor magnets 140a and 140b that have passed the holding section A2 may be accelerated by receiving a relatively large magnetic force from another unit stator magnet group GU located ahead in the jumping section A3. The rotor magnets 140a and 140b can move along the rotation path P by repeating this process, and as a result, the rotor 130 can maintain rotation.

The jump section (A3) is a section in which the stator magnets 120a and 120b are not disposed, but the magnetic resistance from the unit stator magnet group GU through which the rotor magnets 140a and 140b pass is minimized and the rotor magnet ( This is a section in which the forward attraction from another unit stator magnet group (GU) located on the front side of 140a) (140b) is maximized. Accordingly, the moving force of the rotor magnets 140a and 140b can be amplified in the jump section A3.

Control drive 150 may provide rotational or braking force to rotor 130. In a state in which the rotor 130 is stopped, the control drive 150 provides initial rotational force to the rotor 130 so that the rotor 130 may begin rotating movement.
