TAKANO Bistable Rotary solenoids apply cylindrical permanent magnet for rotor and rotary motion is performed by attraction and disattraction of magnetic pole generated by rotor and yoke.
TAKANO Solenoid makes direct rotary motion without any axial movement, which is a long life structure. It is difference from the conventional other rotary solenoids which make mechanical axial mortion and change the axial mortion to rotary motion. |

| 1.Bistable |
Rotate to either side, left / right by changing direction of electrification.
Without electrification, the holding power of the permanent magnet holds the position. |
|
| 2.High output and high response speed |
| Reciprocation is done by changing the direction of electrification without using spring, which enable the products perform high output and high response speed. |
|
| 3.We also have return spring type. |
| The products has simple drive circuit and response to feel safe. |
|
| 4.Operating angle can be set at wide range. |
| Any operating angle within 90° can be set. |
|
| 5.No movement of axial direction and low operating noise. |
There is no movement along the axial and also stopper is located outside, which lower the noises.
For the products which as built-in stopper, the stopper material is examind to lower noise and librations. |
|
| 6.Long life |
| No mechanical moving part is used except a ball bearing, which enable the products to have Long life. |
|
| 7.Many selections |
| Please select according to your needs and usage. |

| Structure and principle of operation |
|
Features of structure is ; Using cylindrical shaped permanent magnet and yoke head is positioned relatively closer.
The magnetic flux by the permanent magnet passes to direction of the dotted line arrow.
Turning on electricity to the coil as Fig.1, flux of coil electric current passes to direction of the chain line arrow.
Both magnetic flux are added with the magnetic air gap ga, with the gb subtraction are done.
The rotary torque which it tries to turn the rotor works to direction of rotation of the clock. |

| Drive system |
|
To run Bistable rotary solenoid, need stopper to adjust operating angle and need to change electrification direction.
To use Bistable solenoid, please make sure the followings; |
| |
1. External stopper
Stopper is not built-in to bistable solenoid itself.except some models Please provide the stopper which stipulates operational angle mechanically.
Please use cushion rubber or other buffer materials otherwise mechanical impact may create breakdown. |
| 【Principle of operation Explanation】 |
| ①When received (stopper is not attached), positional relationship of magnet and shaft D-cut is as below A) or B).
As below A) or B), positional relationship is stable (magnet force balances) |
|
②To use, move shaft D-cut from the original position to shift position relationship and set outer stopper.Reference point, a center of shaft swing, which is a reference point of outer stopper setting is 0 degree position described
in outer dimension drawing of brochure.
Takano sets actual working range ±45 degree from a center of shaft swing (operating angle equal to or smaller than 90 degree)
Please set outer stopper within this range. |
 |
③As turning on electricity after setting outer stopper, coil will be live with electricity to generate polar character at yoke as below.N pole and N pole,S pole and S pole of magnet and yoke are repelling each other and N pole and S pole are attracted each other,thus rotate as below.
By switching over polar character of electricity, polar character of yoke will also be switched over and rotate the other direction. |
 |
④By turning off electricity, there will be no generation of polar character by electric current .
At the same time, magnet will have a force to return to the stable position ( magnetic force balances)
as its original position (stopper is not attached). This force will become holding power. |
 |
2. Drive circuit
To run Bistable rotary solenoid, need to change electrification direction.
Fig. 2 shows typical drive circuit.
TAKANO offers drive circuit as Rotary solenoid related product. |
 |
3. Temperature rise of coil
When driving continually above rated voltage, coil temperature rises and becomes cause of damage.
Please refer the catalog, and choose the appropriate type. |
