I have found an electric motor in my home and I want to estimate how much time it can operate until its temperature becomes too high and eventually build a cooling system for it (I have seen that there are for instance many simple peltier cooling systems at fews $, like this one).
Unfortunately I have not found the datasheet of my motor on the web. I have only the following plate data:
Obviously it is not possible to make accurate evaluations without specific data, but it is sufficient for me a help to obtain a very rough estimation.
Basically, it is an AC 230V electric motor of 160W. It is structured in this way:
The metal rod on the left is rotated by the motor (inside the metal tube on the right). The motor theoretically reaches the end and then reverses the rotation; however I do not need this function and therefore I have removed the limit switch, therefore the motor can turn clockwise or counterclockwise indefinitely (therefore ignore the information: course 300mm).
What I want to know/estimate is:
which is the maximum temperature for this kind of device? I need only a rough estimation (like saying that for a generic Integrated Circuit we do not want to overcome 75°C). Then I may measure the temperature while using the motor and see when it reaches this critical temperature.
does the plate data give some informations about the maximum time of operation?
Is there a criterion for choosing the cooling system (in a rough way)? Is it a good idea to compare the power of the engine (160W) to the power flow offered by a certain cooling system?
