i think that you forget the inefficiency of the solenoid it self. the energy put into the solenoid is not all energy that is used to pull in the plunger, that's why i use the force from the datasheet.
a pulse of 2mS 1.5Amp did not work to pull the plunger inside.
I have now included the...
1. 1.94 Ω + 200mΩ for the driver
2. 1.45 A at 9mm stroke(horizontal position)
3. 8 mH
4. 100% duty: 3V, 50% 4V, 25% 6V, 10% 10V.
extra:
plunger weight: 14.2g
spring strength:(max. 0.8N)
I would like to charge the capacitor to about 8V or 10V.
The force of the solenoid with 10V at...
hmm let me take a look at that.. and try to add that to my current calculations. I'll be back :)
//edit
The energy placed in in the inductor before it starts moving the armature is about 0.017J compared to 0.15 i know i need in the capacitor.
So that is about 12%.
although when the inductor is...
It is not about the velocity being zero at impact but knowing the minimum capacitance of the capacitor that is used to drive the solenoid.
i know the force increases, but I take the worst case scenario because i can't integrate the characteristic in my formula. With the worst case i am sure it...
Heey guys,
I have a problem.
I want to calculate the minimum time i have to activate a (latching)solenoid so that its final velocity is 0 m/s when it hits the inside.
Well I know the following things:
F= m*a
I know the force and the mass, so a can be calculated.
V = a*t.
the average...
