Put a minuscule propeller on the shaft of a cell phone vibrator motor. The generation power will depend on water mass flow speed. This style ---->
I think you are asking how to join the thread to the motor. If you have the tools, the most accurate method is to drill a hole the size of the motor shaft in the end of the threaded rod. It needs to be >5mm deep, more is better. Then make a saw cut across the diameter of the rod so it divides it in two across the hole you drilled. Finally, insert t
One possibility is to look among ads in the Business-Promotions-Advertisements section. Resourcefulness is called for. How much of the assembly needs to be replaced? How much can be left as is? Is the shaft encoder an integral part of the drilling equipment, or is it an add-on electronic component? Where does the signal from the encoder go? Do
If you need to measure rotational frequency of your motor there are all sorts of encoders or mount magnet on motor shaft and use Hall effect pick-up. ... Just guessing
Just twisting my 66 year old head from side to side as fast as I can. I reckon I can go from 90 degrees to -90 degrees and back in .7 of a second with any over shoot. Which in rotary terms is only 1.4 revs/sec or 84 RPM. A servo motor from a flying model aircraft will not be fast enough, a stepper motor would be, but would be expensive. I would
Can you post a picture looking at the end of the motor shaft. The plastic disc may be for an optical encoder.
This thread has two pages of discussion about an air-core transformer in a spinning clock. - - - Updated - - - It has a link to this project on the internet: My suggestion is to install a cassette m
I think generally you will want to stay on M6 as much as possible for series resistance and shunt capacitance reasons. A good planarized process ought to not care whether you take the stairs or the elevator shaft. But that can be a question - are stacked vias going to cost you any yield or reliability relative to non-coincident? That comes down
Hello everyone. I'm new in this forum and maybe my question is not for this but I don't know where to ask for this. I have searched on internet regarding this but I haven't find something like I want. Right now I'm trying to make a CNC machine, mainly for PCB drill/mill. My question is where I can find information related to spindle constructio
Hi All, I am working on a project where I need to implement distance measurement technique using some kind of a sensor. This system will be used to measure horizontal and vertical distance between which the Potato Bin Piler's shaft will move. This distance can vary from 10mtrs and may go as far as 75mtrs. I had some research and found some "stri
I cannot see the size of your jack and you did not describe it. Its plug might have an 1/8th inch shaft or a 1/4 inch shaft, I think it has an 1/8th inch shaft. A jack for stereo headphones has switches on it so that speakers are disconnected when the headphones plug is plugged in. It has 5 terminals as I show here. Maybe your jack has (...)
Hi, I know '#' in verilog means delay time. What is its meaning in this verilog-AMS example? I do not see the explanation in verilog-ams reference book. Thanks, module motorckt; parameter real freq=100; electrical gnd; ground gnd; electrical drive; rotational shaft; motor m1 (drive, gnd, shaft); vsine #(.freq
Thank you for your immediate response, I use UCC3626. My engine has Hall sensors 120 , two quadrant. I believe that the problem is the management of the IR2110 in HO out that despite the bootstrap capacitor and a charge pump system, made with a 7 kHz oscillator, does not change status than its LIN. After turning on the circuit by increasing the vo
7. For servo application, accurate position of rotar required, PMDC is used AKA "stepper motor". because of the difficulty of manufacturing very large magnets, I doubt if these are available for a greater power then a couple of kilowatts. BLDC is normally 3 phase so the rotar can only lock at 6 positions , so the shaft position is only know to be +
Certainly the vibrator is no problem, just about all the ones fitted in mobile phones will work. They are simply tiny motors with weights on the shaft to throw them out of balance as they turn. More volts = more shake. There are many on Ebay and through normal component distributors. However if you have to fit the rest of the electronics, particul
They work exactly like the pen mechanism Akai Bukai describes. The 'heart' shaped track is in the plastic of the moving shaft of the switch and a tiny steel spring wire travels around it to provide the latching action. It is exactly the same method as used by most push on/off power switches on dometic equipment. If this is a mechanism that will op
It appears the mechanism under the arm bearings is only used when 'auto return' is activated so if you exclude that from the possibilities, only the arm pivot itself seems able to create the friction needed to make the noise. I suggest you clearly mark the position of the arm shaft relative to other parts then dismantle it and remove the bearings.
in my panasonic servo motor there are three encoder outputs namely A , B , Z, If i connect cro i am getting square wave in a and b terminals but only noise in z. please explain about A B Z TERMINALS why i am not getting output in z?
Dear friends I had made a stepper motor full step drive which was started jamming after 3 month of run. after jamming when i apply mechanical force to shaft by plier it releases and starts working fine but after 3-4 run this problem repeats.
Watch how a steam locomotive's wheels convert linear motion to rotary. You might use the same principle, in reverse. There is a miniature model of a steam engine which does the same thing. Also look into the nut and threaded shaft. Spin the shaft. The nut travels linearly.
