Abstract

PURPOSE:To decrease the electric power required by providing a phase difference to the changes in the facing areas of the magnetic poles for the rotor and the magnetic core for the stator which occur along with the revolution of the rotor. CONSTITUTION:While the rotor 9 rotates for -30--90 deg., the outside plane 8'1 on the permanent magnet 8' is facing the whole plane of the magnetic core 4' without changing its facing area even if the rotor 9 rotates a little bit. However, the outside plane 8-1 on the permanent magnet 8 is facing the magnetic core 4 and the auxiliary, magnetic core 2. Therefore, when the power is conducted to the coil so that the circular arc plane 4-1 will be the N pole, the rotor 9 rotates counterclockwise, resulting in that the rotatory power acting on the rotor 9 is in proportion to the alteration ratio of the facing area between the outside plane 8-1 on the permanent magnet 8 and the circular arc plane 4-1. Then, when the position of the rotor 9 is almost at the neutral point, a uniform rotatory power acts in proportion to the alteration ratio of the facing area between the circular arc planes 4-1 and 4'-1 on the iron cores 4 and 4' and the outside plane 8'-1 on the magnet 8'. When the rotor is in the position of +30 deg.-+90 deg., the rotatory power acts on the rotor 9 in proportion to the alteration ratio of the facing area between the outside plane 8-1 and the circular arc plane 4'-1.

[Detailed description of the invention] (a) Industrial application field The present invention relates to a bistable rotary solenoid, which is a part of an actuator, which consumes power only during operation and does not consume power when in a holding state. In particular, the present invention relates to a bistable rotary lean renoids that are smaller in size and consume less power than conventional ones, have a large operating force, and can arbitrarily set the magnitude of the holding force.

(B) Conventional technology Conventionally, most bistable solenoids are of the direct-acting type, in which the plunger is held by the magnetic force of a permanent magnet at both ends of the operating range, and two coils are energized during operation. Due to this, the holding force of the permanent magnet is canceled by the excitation of one coil, and the plunger is attracted to the other by the excitation of the other coil. There is a rotor that can rotate in both directions, and is operated by energizing a rotor formed by a circular permanent magnet magnetized in the radial direction and a stator coil placed opposite the rotor.

In the former case, the attraction force of a normal renoid is inversely proportional to the square of the stroke, and one coil is used to cancel the holding attraction force, so the initial operation attraction force is quite small compared to the electric power. -For example, external size 18X18X5
When the stroke k is 4 mm with a power of 0 mm and 5 W, the initial suction force is about 50 gr even with good performance. If the electric power applied to the coil becomes too strong, the attraction force of the permanent magnet will be canceled and so-called re-adsorption development will occur, and the initial attraction force will 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.

It is facing the entire surface of the rotor? Even if it rotates a little, the opposing area does not change. But a permanent magnet? Outside rkJ/-
When the rotator rotates while facing the /ld magnetic core G and the auxiliary H core λ, the opposing areas of each increase and decrease. Therefore, if electricity is applied to the coils R and R so that the arcuate surface of the magnetic core R becomes the N pole, the outer surface of the permanent magnet r? The rotor attracts attention in the direction in which the facing area increases with the S pole of -/? rotates counterclockwise. Also, in that case, what about the cylindrical surface and outer surface of the auxiliary magnetic core? −
Since the area facing / decreases, the total magnetic flux flowing through the yoke / does not change, and the magnetic flux density on the facing surface between the outer surface /'-/ of the permanent magnet l and the arcuate surface '-/ of the magnetic core D does not change. In this state, the rotational force acting on the σ-tar is the outer surface/-
It is proportional to the rate of change in the opposing area between / and the circular arc surface /, and if the current is constant, the position of the rotor 9 will be 190°.
It remains almost constant between 1 and 30 degrees.

Therefore, coil! as well as! When energized, a rotational force in an arbitrary direction acts on the gerotor depending on the direction of energization, and in this case, there is no change in the magnetic flux density of the arcuate surface 2-/ of the auxiliary magnetic core 2 as the rotor rotates. In this state, a constant rotational force is applied to the rotator in proportion to the rate of change in the opposing area of the arcuate surfaces of the magnetic cores G and D' and the outer surface /'-/ of the permanent magnet L. Therefore, if the current is constant, the rotational force will be approximately constant within the range of +-30 degrees from the neutral point of the rotator.

As a result of the above, the bistable rotorinoid of the present invention has -
A nearly constant amount of rotational force can be applied to the rotor with a 180° frontage from 90° to +90°.In actuality, the ease with which magnetic flux passes, that is, the permeance value, is greater when the rotor is on the left or right side.
Since the 90° position is somewhat larger, these two points become stable points and maintain a constant holding force even when no current is applied, resulting in a so-called bistable rotary solenoid function.

In FIG. 5, magnetic cores /4 and /4t' are formed slightly larger in the upward direction. Therefore, the facing areas of the circular arc surfaces /Ku/ and /Ku/ and the permanent magnets ♂ and 1 become narrower, and the change in each facing area when the rotator rotates left and right from -90° to +90° is shown in Figure 6. It becomes minimum at the center of the rotation angle of the rotator. 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 as a magnetic circuit is small and the efficiency is high. The measurement results showed that a product with external dimensions of +8XI8X40 required only 1 to 1.3 W of power to generate a torque of 43 grCm, which was 4 to 5 times more efficient than conventional products.
