Gosh. Thanks very much. Of all things I have a physics degree and was stumpt on how one could make such a simple wee motor with such neat properties. Save me from dissecting it. My wife gets upset when I take new things apart.
i have small motor 220/240 5/6 rpm @ 4 watt, i want attach them into pulley or gearbox for veryy slow rotating turntable (diamter about 1 meter), probably max weight about 3 kg's do you think my motor were adequate enough? i am not good at calculate pyhsic things, thank you
Hey Chris, would it be possible to wire these in a way that you can control the motor being able to spin in both clockwise and counter clockwise direction?
A synchronous motor is started as an induction motor and is brought to about 95% of synchronous speed. Then the DC field excitation is applied and the motor pulls into synchronism. Chris
Im not to good with these motor types but it might be that either the synchronous speed in the stator became too fast for the rotor to keep up, or the torque the rotor had to rotate became too much. The condition you described sounds alot like whats called 'hunting'. Unfortunately my problem is i only have theoretical background at the moment.

Thanks for the comment
Thanks for sharing these insights.. very interesting!
How to make this motor rotate in only one direction?
3:34 I saw the shade changed speed in quite a robotic way. This probably indicates the frequency of the power is computer controlled or monitored.
Why would mine jurk its 1.7 2 rpm mk02n wall socket light spin mirror ball
Just saw me how to make the one table spin mine identical I use lithium battery but got some jerk that's it slow rotatin but got Nada

I wanted to drive this motor on 12 v dc are there any driver circuit circuits i changed motor coil so it's driven on 12v ac
I have a servo motor and want to know if it is a synchronous motor or a synchronous motor without turning it on(SGMGH-09DCA6F-OY
YASKWA ELECTRIC)

TYJ50 Synchronous Motor are sold CW (clockwise) CCW or CW CCW
Chris, would a couple of hairline cracks in the magnet in the smaller motor you show be the demise of my motor?
Yes that could be the cause.
Um how do you start a motor with the coils already energized? Statement did not really make sense.

I got it to turn for awhile then wanted turn in the opposite direction and then stopped.

look inside your motor, you will see ONE coil! how is it the same like your paper diagram? not the same.
The top diagram is a 3 phase synchronous motor, the tjy 50-8b1 is single phase with one coil.
thanks for the comment.
