I is new member , I'm vietnammese
hello everyone !! anyone can help me ..please !!
my stirling : 1 / diameter cylinder : 16mm , long : 65mm
displacer , long : 43 mm , diameter : 14.7 mm, stroke : 20mm - aluminium
2 / power cylinder and piston diameter : 16mm , stroke : 14 mm (ratio about : 1:1.5) , piston power long 16mm.- aluminium
3 / flywheel : diameter : 55mm , thick : 12mm -brass
4 / The displacer leads the power piston by 90 degree

this is my stirling engine picture

thanks everyone !!

Hello thanh-cuibap, the motor looks ok from the photo. Important things to look at: does the piston fit very well without friction, and without leaking air. Next are the bearings on the main shaft free turning, ball bearings best(spare bearings for skateboard are ok). The displacer, if it is a cylinder must not leak air, and it must not rub on the outer hot cap, also where the rod comes out there must be minimum friction but as near as no leak as possible.
It only takes one thing not quite correct, and these motor won't go, I'v had a sore wrist turning a motor over trying to start it, then come back maybe days later, given the flywheel a turn, and the motor has started, they can be frustrating.

Hi Ian S C !!!
thanks for your guide . I will check it again !
..but do you think is slightly smaller flywheel ???
sorry , my english not good .

Don't worry about your English, I know no Vietnammese.
The flywheel looks ok, but you could try one a little bit larger, anything up to 100 mm. I find that if my motor is good, it will run very fast, but with hardly any power with no flywheel .
Another test that can be done, using an electric motor to drive the Stirling Engine in its normal direction, at some where between 500rpm, and 1000rpm. After a few minutes you should notice that the hot end of the displacer chamber is starting to get quite cold, 10 minutes or so and a light frost should appear. The last time I tried it with one of my motors drive another the temperature went to minus 20*C in 20 minutes, the ambient temperature that day was + 20*C. Running the motor this way helps to free it up, so that it has a better chance of running when you put heat to it.

Add something to learn !!
