Hi, I never really worked with motors. Are these calculations valid?
Just feeling some specs out of the air I would say about 20 cm at about 60-180 times per minute with a force of 4 kg. Translating it to proper units, I get:
0.6 m/s max @ 40 N. Although, I guess the 4 kg is more important at low speeds, so perhaps I could actually use the low-spec and get something like 0.2 m/s @ 40 N. So that should amount to power of 8 Watts radial or axial power. Is that correct? Is the terminology correctly used?
Torque does not matter, right? Getting the correct radial power is of essence, and then gearing can be used to use the power correctly, correct?
What does "nominal torque" mean? What other interesting torques are there?
Can I gear using "belts" and wheels (what are they called?), you know the kind find in for example cassette players, although larger in my case of course. The kind that has rubber bands around it. I am just guessing they will be cheaper?
I found one engine here:
https://www1.elfa.se/data1/wwwroot/assets/datasheets/rjES_RoHS_e.pdf
4IK25RGN-CW2E
It is rated at 25 Watt axial power and has some type of speed controller and everything. Is there any danger working with this type of device at home? I am thinking of putting both the engine and speed controller unit into a box, and just let the shaft stick out from it. Anything in particular I should have in mind concerning safety? Do I need to connect it with a grounded outlet?
