[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a bistable rotary solenoid, which is a type of actuator and consumes power only when operating and does not consume power when in a holding state. In particular, the present invention relates to a bistable rotary solenoid that is smaller in size and consumes less power than conventional ones, has a large operating force, and can arbitrarily set the magnitude of the holding force.

(b) Conventional technology In the past, most bistable solenoids were of the direct-acting type, in which the plunger was held by the magnetic force of a permanent magnet at both ends of the operating range, and two coils were energized during operation. Accordingly, a type has been used in which the holding and attracting force of the permanent magnet is canceled by excitation by one coil, and the plunger is attracted to the other by excitation by the other coil.

Further, rotary solenoids that can rotate in both directions include a rotor formed by a circular permanent magnet magnetized in one radial direction;
There are some that operate by energizing the coil of a stator provided opposite to it.

In the former case, the suction force of a normal solenoid is inversely proportional to the square of the stroke, and one coil is used to cancel the holding suction force, so the initial operation suction force is quite small compared to the electric power. As an example, if the outer diameter is 18 x 18 x 50 mm and the stroke is 4 mm with a power of 5 W, the initial suction force will be about 50 gr even if it has good performance. Furthermore, if the electric power applied to the coil is too large, the attraction force of the permanent magnet is canceled and so-called re-adsorption development occurs, and the initial attraction force does not increase.

Furthermore, in the latter case, the torque is large at the center of the rotation range, but small at both ends, and when electric power is added to cancel the holding force, the effective operating force is extremely small.
As an example, the initial drive torque when the external size is 26 x 26 x 30 mm and the rotation angle is 120° with 5W power is:
It is about 40gr・cm.

(c) Problems to be Solved by the Invention The present invention provides a phase difference in the change in the opposing area between the rotor's magnetic poles and the stator's magnetic core as the rotor rotates, thereby generating a force similar to that of the conventional solenoid. The present invention provides a bistable rotary solenoid that can reduce the amount of power required to produce a fraction of the amount of power required.

In FIGS. 3 and 4, if the rotation angle α of the rotor 9 is set to +-90 degrees left and right symmetrically with respect to the center, then
When the rotor 9 is rotating from -30° to -90° as in the case of FIG. 3A, the outer surface 8'-1 of the permanent magnet 8' faces the entire surface of the magnetic core 4', and the rotor 9 There is no change in the opposing area even if the rotation is performed. However, the outer surface 8-1 of the permanent magnet 8 faces the magnetic core 4 and the auxiliary magnetic core 2, and as the rotor 9 rotates, the opposing areas of each of them increase or decrease relative to each other. Therefore, if the coils 5 and 5' are energized so that the arcuate surface 4-1 of the magnetic core 4 becomes the north pole, the rotor 9 will be attracted to the south pole of the outer surface 8-1 of the permanent magnet 8 in the direction in which the opposing area increases. Rotate counterclockwise. In addition, in that case, the auxiliary magnetic core 2
Since the opposing area between the cylindrical surface and the outer surface 8-1 of The magnetic flux density on the opposing surface does not change. In this state, the rotational force acting on the rotor 9 is applied to the outer surface 8-1.
It is proportional to the rate of change in the area facing the arcuate surface 4-1, and if the current is constant, the position of the rotor 9 will be approximately constant between -90° and -30°.

Next, when the position of the rotor 9 is approximately at the neutral point as shown in FIG. 3B, there is no change in the opposing area between the arcuate surface 2-1 and the outer surface 8-1 of the auxiliary magnetic core 2 as the rotor 9 rotates. . However, the facing areas of the arcuate surfaces 4-1 and 4'-1 of the magnetic cores 4 and 4' and the outer surface 8'-1 of the permanent magnet 8' increase and decrease with respect to each other.

Therefore, when the coils 5 and 5' are energized, a rotational force in an arbitrary direction is applied to the rotor 9 depending on the direction of energization, and in this case, the change in magnetic flux density on the arcuate surface 2-1 of the auxiliary magnetic core 2 as the rotor rotates is as follows. do not have. In such a state, the rotor 9 has magnetic cores 4 and 4'.
A constant rotational force acts in proportion to the rate of change in the area of the arcuate surfaces 4-1 and 4'-1 facing the outer surface 8'-1 of the permanent magnet 8'. Therefore, if the current is constant, the rotational force will be approximately constant when the rotor 9 is within a range of +-30 degrees from the neutral point.

Furthermore, in FIG. 3C, contrary to the case of FIG. 3A, the opposing area between the arcuate surface 4-1 of the magnetic core 4 and the outer surface 8'-1 of the permanent magnet 8' does not change, and the auxiliary magnetic core 2
The facing areas of the circular arc surface 2-1 of the magnetic core 4' and the circular arc surface 4'-1 of the magnetic core 4' and the outer surface 8-1 of the permanent magnet 8 change mutually. When coils 5 and 5' are energized in this state,
If the current is constant, a constant rotational force can be obtained when the rotor 9 is positioned between +30° and +90°.

As a result of the above, the bistable rotary solenoid of the present invention is able to output a substantially constant rotational force to the rotor over a range of 180 degrees from -90 degrees to +90 degrees. In actuality, the ease with which the magnetic flux passes through, that is, the permeance value, is somewhat larger when the rotor is at +-90° to the left and right, so these two points become stable points and maintain a constant holding force even when no current is applied. , it has a function as a so-called bistable rotary solenoid.

In FIG. 5, the magnetic cores 14 and 14' are formed slightly larger in the upward direction. Therefore, arc surface 1
The opposing areas between 4-1 and 14'-1 and the permanent magnets 8 and 8' become larger, and the change in each opposing area when the rotor 9 rotates left and right from -90 degrees to +90 degrees is as shown in Figure 6. It becomes minimum at the center of the rotation angle of the rotor 9. In this way, the central neutral point becomes a completely unstable point, and there is no stopping at this point during operation. Also, the holding force at both ends is increased and the stability in this respect is increased. However, the rotational force when energized is somewhat weak at both ends. However, when viewed comprehensively, the so-called gap in the magnetic circuit is small and the efficiency is high. The measurement results showed that the power required to generate 40grcm of torque with external dimensions of 18 x 18 x 40 was only 1 to 1.3 W, which was 4 to 5 times more efficient than conventional products.
