So 14VAC@7Hz will give enough power to the motor to spin ?
I will give it a try this afternoon !
I'll rise VERY slowly the AC voltage and keep an eye
on the motor behaviour.
I never heard about this V/H ratio at all..
Thank you very much !
Thank you Bill for such a detailed explaination !
What a treat !
Here are more explanation of what I measured and what I'm about to experiment:
The original Yamaha motor is a 1800RPM (in fact 1714RPM measured) at full speed
and drops to 200RPM at slow speed. If you divide 1714 by 200 you get...
>The diagram of the motor itself looks to be a PSC (Permanent Split capacitor),
>but I'm not clear on why one side of the circuit for it is going through a full wave diode bridge rectifier. Interesting...
The full wave bridge rectifier is to only keep the positive side of the 60hz waveform
to...
Now I understand..
So using the maximum speed tap of a standard table fan (with sufficent motor torque)
and drive it with my variable AC supply current circuit (the circuit shown in previous post)
the overheating will not occur at very low speed ? OK.
By the way, I cannot use a motor with...
I thought these type of variable speed fan had like 3 fixed speeds.. (??)
If I use the maximum speed tap (3 speed taps inside these motor I think)
and drive it with my variable AC supply current circuit (the circuit shown in previous post)
you think it will vary its speed without overheating at...
Hi,
I'm a newbie in the small electric motor hacking world.
I need info about how to drive a standard 120vac motor
with a variable AC source without overheating the motor
at low speed...
Here is my project:
Yamaha organ instrument used to include, in some of their organ,
what they called a...
