Hello. Welcome to Just Answer.
Thank you for requesting me to answer your question.
Typically, these small fans can't be reversed by changing wiring connections.
However, you may be able to reverse rotation by taking it apart and flipping the stator around.
The stator is the stationary component that the rotor spins inside of.
Or, you may be able to take the fan blade off and turn it around.
That would work the same way was reversing rotation.
...same way as reversing rotation (typo)
Reversing the fan blade does not reverse the air flow. The motor has an externally mounted capacitor but I'm not sure how the wires are connected internally based on their colors. The label says the white is common, the black is high and the red is low (there is a 2 speed switch installed also). There is a yellow wire and a brown wire attached to the capacitor.
I agree about reversing the blade. After posting that, I went off through my house to do some "research", and discovered that the pitch of the blades will stay the same if you take it off and flip it over before putting it back on.
So I erred on that post for sure.
However, it's extremely unlikely reversing can be achieved through wiring changes.
If you don't mind standing by, I'll look for it Online, to see how difficult it would be to reverse the mounting on the stator.
I don't mind waiting. I managed to reverse the direction but the motor doesn't run at full speed, so I need to know the proper wiring.
It doesn't appear that P2SP is a valid part number. Are you able to check again for the part number?
It's hard to tell because the label is damaged but I think that is supposed to be at least part of the model number not the part number
I'm sorry, but I'm unable to find any relevant info Online. Perhaps one of the other guys has reversed one of these fans through connection changes. It may be best for me to opt out, to give the other electricians an opportunity to weigh in.
Maybe my hopes are too high but I hope you can find the solution.
How hard would it be to put the wiring back to original condition? Reversing the stator may be a better option.
Is it a direct drive fan?
The whole model number appears to be 'D-XIN-PSC-6P2SP'. It is a 1/4 hp motor. Yes, it is direct drive.
That is a good number. However, it doesn't bring up any images for me to reference. I really do appreciate the request, but unfortunately, it doesn't appear I am able to assist you any further. I apologize for that, it doesn't happen very often. I'll opt out to open up the discussion for the other electricians.
Thank you for your efforts.
Happy to help. Thanks again. Another expert should be along shortly, but sometimes it can take a little while. Your patience is much appreciated.
Would it be advisable to continue this chat tomorrow?
You can, if that's what you prefer. Do you need instructions on how to get back to this conversation.
Yes, thank you.
Log on to www.justanswer.com, and click "My Questions" in the upper right corner of the page. That should take you to a page that has a link to this chat. One thing to note... once I opt out, the chat feature will go away, and the question will switch to a Q/A format, which is more like a message board.
I would rather stay in chat if that still means access to experts.
After all the hour is getting later
My opting out opens the question to all experts, but unfortunately, also takes the chat feature away.
Would it then be advisable to wait until tomorrow so that others can do proper research without undo stress?
Yes, that would likely be the best way to go. Although, some of the guys in this category are night owls, and are up answering questions at all hours of the night. It's really you choice.
sorry... YOUR choice.
Then let's keep going
Just to clarify, do you mean with another expert, in the other format?
That sounds like my only choice
Until next week, when a new and improved version of the site is launched. I do apologize for the inconvenience though.
I appreciate your candor and your attempt at the solution. I hope there is a solution.
I'm sure there is. If you got it reversed, the speed problem is likely capacitor related. But I am hesitant to suggest connections when I don't have a lot of experience with reversing small single phase motors of this type. I would prefer to have another expert step in, over myself suggesting something that damages your fan.
I understand and thank you very much
Flipping the stator would work, but it's okay if you prefer to get it done through wiring changes.
Have a great night, and thanks again for your patience. Take care.
Reversing the blade does not reverse the air flow.
The label says the white wire is common, the black is high, and the red is low. There is a brown wire going to one side of the capacitor and a yellow one going to the other. Also there is a 2 speed switch in the mix as well. The black wire was going to the 1 position on the switch. The red wire was going to the 2 position on the switch. The white wire was going to the common side of the line. The L position of the switch was going to the hot(black) side of the line.
Reversing the blade does not change the direction of the air flow
Flipping the blade changes the trailing edge to the leading edge and causes the air to flow in the same direction. Besides, that would be too easy!
Now you understand why I am chatting with you all. I am willing to wait until tomorrow for a difinitive answer if there is one.
No, I'm sorry, not now. There were wires running from the switch to the motor just as I explained with the colors that I listed.
I managed to reverse the direction of the motor by attaching the hot(black) wire to the other side of the capacitor, but it doesn't run at the proper speed, so I need a better answer. I appreciate your analysis, but it's not enough. Maybe tomorrow we can give it a fresh approach or find more information.
I will accept your answer even though it is not what I had hoped for. I will have to settle for trying to swap the rotor and stator. Wish me well and thanks for your efforts at this late hour.
I'm sorry I can't comply with your request. I have modified the wiring and besides, it wouldn't give you any more info than I have explained. There is no connector board or anything else hiding the wires going in and out of the motor. Perhaps after I disassemble the motor it will become more clear. Thanks again for you efforts.
