This person has ZERO knowledge about fan motor. I have checked his other videos. This was created intentionally by this person to attract viewers. This is the same fan he has shown in other videos. This is Orient fan from 80s. Do not like and subscribe his channel. He will spread more ignorance if you support this person.

How do you know this was created intentionally? Please revisit all the videos again, this fan is not used. Yes, there was a problem on reverse rotation of fan in a video, that doesn't mean spreading of ignorance. Thanks 🙏🏽

Do not follow the process shown in this video. This person has no knowledge about fan motor. He has made wrong connection. Fan is rotating in opposite direction check 17:03 time. For no reason he has put grease in false cover time 14:14 . Outside bearing time 10:24. His measurements are wrong at time 12:05. This great Dumbo doesn't have sense that his fan is rotating in opposite direction time 18:43 . You will ruin your fan if you follow his video. A million thumbs down 👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎.

You have ZERO knowledge about fan motor. PSC permanent split capacitor motor has no running and starting winding. Outer winding is Primarily winding and inner winding is secondary winding.
@Satyaprakash81102
@Satyaprakash81102 Месяц назад
It's a shame that you have no knowledge about fan motor and you are teaching others wrong information. There's no running and starting winding in a PSC/ permanent split capacitor motor. Since both windings are always connected to power for the whole time. The outer winding is primarily winding and inner winding is secondary winding. Primarily winding is directly connected to the power line and secondary winding is phase shifted. Damm your test procedure. The wires must be sanded before measuring resistance. Your fan is running in opposite direction. Shame on you. Delete this video and Stop spreading wrong information.
