What kind of rat is it? Does it have a latin name?

 

Does it have a latin name?

Flavius Verminious.
Max.

 

Must be an awfully big motor to have a 1/2" spindle -

1/2" pulley mentioned , no mention of motor spindle!!
Max.

 

as Max alluded to in post # 4, contraption is a drum about 46 cm dia. turning at 1 revolution in 3 min & 34 sec. ( that is slow, rat will run up on side then take a nap & run up again.). Surplus houses have many options on geared motors, DC & AC.
Just looked up 2 from Electronic Goldmine, 72 RPM, would need extra reduction of 257:1, G20726; or a humongous reduction of 7776:1, on 6Vgives 1 revolution in 4 min. Operates on 3V to 24V DC. # G20272

Might be easier to just get some less lazy rats.

 

Thanks for your ideas and help.

I am looking to try with the DC motor suggested by Bernard (# G20272).
If not working ok, I will try to gearing down my Wheel, even if it makes the mechanical installation more complicated.

I will let you know the result of my test later.

Hello again,

Just to close this thread.

I bought the DC motor suggested by Bernard, and it is working OK. Torque and speed are perfect.
The only inconvenient is that the motor is very noisy, because of the Inside gearing, but for the moment it is working.

Thanks for the help everybody,

Marcel
