coil

Hi folks, first post. I joined to get some help with this problem. I want to drive a solenoid through a transistor configured to latch on & off, using EDIT - 3x - NOT 2x - hall effect sensors to provide the switching inputs. As the title states; what would be the most effective way to latch...

My end goal is to build a circuit with a wireless charger transmitter module and a led indicator that turns on when the receiver is detected and wireless charging is occurring. I’ve been reading about the analog pings the TX uses to detect RX, Foreign Object Detection (FOD), Q-factor...

I am planning to make solenoid: *Coil = 3.5 Ohm Dc - 3.5 mh inductance *Capacitor = 450v- 1000 uf *Dc Battery = 12v *Dc Booster = up to 400v *Push button switch Iam willing to operate it on 150v or 200v I am worrying about the switch to get damage by the back emf I did some research...

Subject: Online Coil Inductance Calculators yeild different Results Designing an open air coil wound on PVC pipe with the following specs ... Wire = 12 gauged insulated electrical wire from Lowes - Wire Diameter = .125 including the insulation - Turns per inch = 8 - Total Turns = 212 - Coil...

I am designning ac solenoid lock, read the inductive load needs snubber circuit to protect from inductive turnoff transients Here is my design Resistance 8 ohm Main outlet power source 220 - 50 hz Inductance 150 mh Impedance 47 ohm I (rms) ~ 5A So do i really snubber circuit? If so iam...

Hi All, I have made an electromagnet of using 1 mm diameter wire appx 60 turns. here is the problem... i have 600W smps(computer power supply) and i want to use that to power my electromagnet. On smps it shows 3.3V with 25A and 5V with 18A. If i connect my electromagnet to one of these terminals...

Hello All, I am developing a very small I2C controlled Motor Driver PCB Board for a robot for my master's thesis. The idea is simple: Use ATTINY816 to send two PWM signals to the DRV8872 Motor driver to actuate an electromagnetic coil back and forth between two magnets. The PWM signals switch...

Disclaimer: I am not an expert, only enthusiast. Hi, i want to experiment with a small scale axial flux motor and a single coil. The first question is what should be the polarity of the magnets? Same or alternating? The second question is what should be the shape of the coil. Is a core needed...

Hello, I would like to know how do I configure the DFLOP with + -15 V or whatever other voltage. I tried several things but it still has + -1V.

I was looking into companies or startups that were doing things with motors to improve efficiency. I stumbled upon Turntide Technologies, which has a partnership with Amazon. Turntide is making a software-driven motor that "enables precise and reliable control to effectively use every watt of...
