Re: displacer and power piston proportions

ABSOLUTELY IMPRESSIVE...but yet didn't got answer...
if I want to produce about 40Watt...
what is the recommended ratio..? the more higher the better performance or to stay with 1.5:1 ratio?

Re: displacer and power piston proportions

If you can reduce the power piston's stroke to obtain the 1.5 : 1, this is probably the simplest way. The motor as is may run at high temperature with little power. Ian S C you are right! this is exactly what happened.. i need to reach temperature of 350 Celsius so it will start rotate... but my fi...

Re: displacer and power piston proportions

The standard ratio for a high temperature Stirling Engine is 1.5 : 1, swept volume of displacer to swept volume of the power cylinder. The displacer should be about three times its diameter in length. The power piston can have a large diameter and short stroke, or a small (not too small) diameter a...

Re: displacer and power piston proportions

thanks! that was very helpful!
there is anywhey to predict the power i will get at the shaft? in general, there is anywhey to calculate it with exist motor? i have no torque meter..

displacer and power piston proportions

hi everyone!
i am new here and almost got drawn with all the info around here...
my question is pretty simple..
there is any guidelines about the displacer and power piston sizes?
my motor should work with 350~500 degrees celsious on the hot side...
tnks!

gamma stirling engine scale

hello, my name is shay and i build a gamma stirling engine by specific plans and its work good but i need stirling engine that able to produce much more power... my questions is: 1.where can i find good gamma stirling engine plans. 2.if there is any guiding recommended ratio to scale my exist engine...
