Motor start to Vibrate and unsmooth rotate as soon as i apply Power to the two terminal and without connecting the capacitor, yest when i Connect the capacitor it rotates smoothly and yes it Reverse direction when i Connect capacitor to Other terminal but when disconnect it Motor Not stop
Here, I have used a unipolar stepper motor for demonstration, but the wiring connection for this is motor is same as for a bipolar one. We can connect a unipolar motor like a bipolar one by not connecting the center wire anywhere.
@@TechBuild Thanks to you, I was able to get about 5 of them going in no time. Then there was one with 4 wires. I connected one leg from each pair together, then I used couple hundred uF Cap and applied 12VAC. It ran like grape ape. Actually make that 17VAC. For some reason I couldn't find the 12V instead there was a 24VAC but it was only putting out 17 volts.
Since the motor's rotation speed depends on the frequency of the supplied current, which is 50 Hz, the speed cannot be changed using a voltage controller.

Try to connect two electrolithic capacitors back to back in series. (+) (-) (-) (+).. This way is much more better. It is cheapest way. No speed control though. It is for low budget projects. Works great. No heat. No vibration. Clockwise or Counter CW. For circuit positions when reverse voltage excursions are unavoidable, two similar capacitors in series connected “back to back” ... will create a non-polar capacitor function ... This works because almost all the circuit voltage is dropped across the forward biased capacitor, so that the reverse biased device sees only a negligible voltage.
It makes the motor run. Try powering the stepper motor connected in this way without the capacitor, it will just vibrate and hardly move, also, adding a capacitor gives direct control of the motor. Don't worry, the DC capacitor will not blow until its voltage rating is higher than the supply voltage and is connected as shown in the video.

I thought since it has 4 wires coming out it is bipolar. In the schematic center tap is connected to what? Nothing?

Well done!
I'm a bit of a noob: What type of transformer are you using, and where could I get one easily? I keep frying the transformer I'm using currently
I used a 12-0-12 output configuration transformer which had a current capacity of 200mA. I bought it from an electronics parts shop.
Thanks for the help! I used a 2A 120/12, ur circuit diagram and got a 4A pump stepper running =)
Good to know it helped.
Awesome!
Looks much more professional
Abhi Gupta thanks!
Can we control speed by adding voltage controller , if yes then in which type
Since the motor's rotation speed depends on the frequency of the supplied current, which is 50 Hz, the speed cannot be changed using a voltage controller.
@@TechBuild any other option or device to control speed

Hello how can i speed control
Plz tell me
I would recommend this:

Why oh why did you choose this horrible music
????????
You might suggest some other better music.
Thank bhai
Good luck with your project build!
why dc capacitor on ac line?
It makes the motor run. Try powering the stepper motor connected in this way without the capacitor, it will just vibrate and hardly move, also, adding a capacitor gives direct control of the motor.

Do I need capacitor if I use 12 volt DC adapter?
Please make me understand the connection..
NICE
Please share this video if you wish.
Music makes it unwatchable
Can you suggest me a better music, please.
Tech Build perhaps non and commentary
What do you mean by that?
spot on
I hate this music...irritating
Can you suggest me a better music for this?
@@TechBuild .... use soft music ... :)
Kondenzator se vodelá
hello mais on cent fou de ça oki
garbage music, could use some commentary of what you're doing instead
ur right
