QUOTE(gosleo @ Mar 22 2024, 09:41 AM) Another bad point for AC Motor, upon aging, it will produce black powder as it is using carbon brush (small part of the motor that conducts electrical current between the stator and the rotor of a motor). It is consumable parts and will wear-out in time.  SitiNorhaliza1970 liked this post

QUOTE(Zot @ Mar 25 2024, 03:27 PM) Yes you are right. Boss, you sure you supposed to reply to me? The bad capacitor can be due to AC spike in your house or reverse voltage produced by the fan coil. Usually it considered at 2x AC voltage but most capacitor in shop has rating of 450V. If you can find the 500V, then it would have longer lifetime.  I'm calling out that other poster who sounds like a salesperson trying to promote their D/C fans, and so they are spreading bad information about A/C fans to confuse people. |

» Click to show Spoiler - click again to hide... « Then you shouldn't have made the statement like you are an expert at it. You create FUD for readers when you post misinformation, considering that the TS is trying to get information about ceiling fans. But here's the thing - I don't think you are a layperson learning and contributing. QUOTE Alpha and Deka offered many choices, but in term of reliability, they are always having spoilt CBB capacitor (especially AC Motor Fan, unable to control speed or the speed becomes very slow). A layperson only thinks of the capacitor that controls the fan speed, while you know to say the type "CBB" capacitors. |

QUOTE(gosleo @ Mar 28 2024, 02:06 PM) Bro, you must be strong supporter of AC Fan. No offence, AC Fan is cheap and function as it is. Nope, this is not about me. Since I correct the misinformation, I am a supporter of A/C motor fan? That's the logic of a 5 y.o. QUOTE Sorry, I said I am learner on types of motor, doesn't means I dont know about basic electronics. Impressive pictures! Since you already opened a fan to make repairs, how many carbon brushes did you find? Was it the same as the water pump that had carbon brushes in the heater that you looked at?I know about "CBB" capacitor because I fixed it before, not to mention such info is available online easily.     I shall stop here. Thanks for your comments.  Feel free to reply, but I'm going to get back on topic for any further addition to this thread. |

QUOTE(Maknusia @ Mar 24 2024, 02:09 PM) Thanks for sharing, but I couldn't imagine ceiling fan consumption lagi tinggi daripada peti sejuk?! "There are 3 kinds of lies: Lies, damned lies, and statistics." I decided to read the "research paper" quoted, and unfortunately I found some discrepancies. I post an image without any text edits, but with it slightly shortened. I can't get the numbers quoted by the author of the paper. Please decide for yourself if the data can be trusted. Any mistakes in the post are my own. Please correct me if you find any. |
