Assistance needed: Stirling model accessory- how heavy can it be?

Postby Cocktail » Sat Jan 13, 2018 9:29 am

Hello, folks. First post here. I have an idea for a homemade accessory for a stirling engine model, but it is on the heavy side. I'm not sure a model would have enough power to rotate the accessory.

I have no technical expertise, but am told that the way to determine how much power an engine has is through its torque rating. While I see maximum RPMs for stirling models on line, I have seen no torque ratings.

I'm hoping someone who has worked with accessories of various load levels can advise me.

Thanks much!

Hi Cocktail, what is it you want to drive? My engines drive a number of things, generators/alternators, a water pump, a power hacksaw, and fans.
Once you have your motor, you can build a Prony Brake, and test the torque of your motor, and if you also use a tacho, you can check the revs.
