Greenhouse roll up Motor DC24V for Greenhouse Ventilation

Used this very strong but slow motor to open close my pool cover with 3D printed coupler So far has worked great

The product was adequately packaged and arrived on time. After researching many similar products, this one provided just what I needed, high torque, slow speed, and a drive/control (sold separately). I'm using it to turn a compost tumbler which I've calculated to require between 40nm and 50nm torque to turn. This motor was one of the few rated to handle this. And it works like a dream. The product descriptions might not make you understand, but the motor itself has an adjustable "rotation counter" for both directions. You can flip open a small water-proof lid to access the two dials. One sets the max rotations in the fwd direction, and the other reverse. I've set them to rotate my compost tumbler 3 full turns, at which point it auto-stops. Next time, I flip the controller switch in the other direction, it reverses polarity, and my tumbler rotates 3 full turns in the other direction. This arrangement is working well. The reason I only gave it 4 stars is, my motor has NO markings, no labels, no stamped values.... nothing on it to identify which model I got. They sell 2 models, a 60W and 80W I believe. I paid more for the 80W, but they look identical, so I can't tell which one I have.

Low voltage been using these for years

that one good
