TAKANO 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.
It holds the position with permanent magnetic holding power when the electricity is off. |
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.
We have "Bistable rotary solenoid" which makes high speed motion between 2 positions by changing directionn of current and we have "Step rotary solenoid" which has multiple permanent magnetic polers of yoke and rotor to have multiple position control. |

| 1.Main Data
DC resistance value
DC resistance value of standard product at 20°C circumstance.
It is adjustable according to working voltage, energization (electrification) rate, necessary torque.
Inductance
Value at Rotation angleΦ=0°
Saturation temperature rise value of coil
Saturation temperature rise value of coil at time of continual W (Watt) electrification
(Ex) When 10W continues turns on electricity saturation temperature rise value of the coil of RSR20/20 becomes
Δθs≈7.0 x 10 = 70 (°C)
In addition, when electrification ratio is 1/f,
Δθs≈7.0 x W x 1/f
Electrification ratio of 10W at 10m • secON, 10m • secOFF would be
1/f = ON time/(ON time + OFF time) = 10/(10 + 10) = 1/2
(refer to Fig.3) Therefore Saturation temperature rise value would be
Δθs≈7.0 x 10 x 1/2 = 35 (°C)
Time constant of temperature rise
After impressing fixed voltage for t-min.(hours), the temperature Rate-of-Climb Δθwould be
Δθ= Δθs (1-e )  (e: Base of natural logarithm)
Insulated class
E-type (120°C) is normal. Special specification such as classH (180°C) is also acceptable.
2.Torque quality figure
The solid line shows occurrence torque value from angle of rotation (- Φ) to (+ Φ) at the time of W (Watt) input.
When electrification direction is made opposite, as in the dotted line it draws torque curve line from (+ Φ) to (- Φ) which is made symmetrical to rotation angle Φ=0° .
0W curved line displays the holding power by the permanent magnet at the time of non electrification.
Holding power of opposite direction occur also to (- Φ) direction.
Rotation angleΦ =0 becomes the position where position of D cutting of the shaft shows in the external size figure, becomes the central point of usual distribution operation.

3.Response characteristic
This shows period from at the time of power source input to the end of operation when V (Voltage) input.
Please refer this information to select model when responsiveness is required.
4.Others
Bearing
Standard types use the ball bearing, but there is also a type which uses the oilless bearing. (refer to model information)
Please select based on your requirements such as durability.
Lead wire
Using UL Recognition product
We do also the terminal processing of line long modification and connector installation.
Shaft
Standard types has D-cutting. However key way, tapping other size changes are acceptable. |

| Electrification ratio |
|
|
| As shown Fig-3(a), Following to the lapse of time, when operation of electrification for t-period and pause for th-period repeatedly continues, |
 |
As shown Fig-3(b), when rotor holding power being insufficient, following to the lapse of time, when operation of electrification for t-period Ww(Watt) and hold for th-period at Wh(Watt) repeatedly continues, |
 |
When Electrification being irregular and when (1) nor (2) formula can not be used, frequency of operation was done n-times during sufficiently long time T. |
