Thank you very much, consultant.

I am very grateful for your valuable comments and detailed analysis on the functioning of the fan and its regulator. It is true that the triac is often the most vulnerable part in these systems, but since we have to do the work at home, we do not always have all the parts at hand. In that case, for those who will do the home repair work at home, I think it is better to buy some new parts and install them, which are available at a very low price. And I am glad that you brought this up.

I find the use of a 5 RPM synchronous motor instead of a traditional gear system very interesting, as it provides more durability and efficiency. I am happy to share this knowledge and contribute to the learning of more Steemit members of the Home Repair Club.

I will continue to create useful content so that we can all learn together. Thanks again for your support and inspiration.
