Hi all,
I need to create huge Matrices/Arrays of Solenoids(like clusters of 500 to 5000 at a time).
I have so far managed to wind a coil around an Aluminum core of <4 mm OD with an ID of 2mm. which lifts 40 grams easily with a 24V DC source and draws 2.4 Amps!!!
For winding I am using a 0.3mm wire which goes around the 5cm length of the solenoid 10 times.
1- All solenoid experts, how does the performance of the above solenoid looks to you, is it's force within ball park of what a 5cm length x 10mm OD solenoid should be(it pulls like 80 grams on a flat surface and lifts in the air 40g free and clear)?
2- I have investigated the required circuit a lot and so far the only options seems to be like the keyboard Matrice approach! Any better suggestions on that please? Note, the Solenoids need to be active only one at a time and then only for .5 second and that particular one won't be used again for at least 30 minutes, so heating won't be a problem but keeping cost to a minium will be.
I look forward to all the advice the experts can provide here.
thanks
