SOURCE: What is the correct schematic of any stand fan winding?

If you cut the coil ... your chance of actually making a repair are very limited. If you are skilled at using a volt/ohm meter, you can probably tell which one goes to which one ... actually making the solder or cold repair and getting it back into an enclosure will be difficult.

You can check the individual pieces of the wire using the ohm part of your meter checking contunity.

How give turns of the usha padastal hyspeed fans coil rewinding


The only time that I have rewound a transformer, I measured the length of coils when they were unwound as opposed to knowing the number of turns.

How to Reverse the Rotation of Single Phase Capacitor-Start Electric Motors


Reversing the rotation of electric motors can be done easily with 3-phase motors. This can be easily achieved by swapping the connection of any two motor leads. But 3-phase motors are usually found and used for industrial purposes. The ones found and used in our homes, from water pumps to electric fans, are single phase capacitor-start type motors. Unlike 3-phase motors, reversing the rotation of single phase electric motors is no easy task. Swapping any two motor leads will not result in the reversal of the motor rotation. Analysis of the motor windings and connections are necessary before any modification can be done to achieve the desired result. Let's take a 3-speed single phase capacitor-start electric motor with electrical diagram shown below as an example. Make sure the motor is disconnected from the power supply before attempting to follow this tip. This tip is intended only for individuals with electrical knowledge, necessary tools, and understand the risks associated with handling electrical equipments and devices.

The first step in the process is determining the start winding which is connected to the line (AC white) and to one side of the start capacitor. To accurately determine the start winding, disconnect all motor leads from the start capacitor and the speed switch for multi-speed motors and then setting your ohmmeter to the lowest scale (R x 1), measure the resistances between the AC white line and each of the motor leads connecting to the start capacitor. The one with the least resistance is the starting winding lead.

Once the start winding lead going to the capacitor is determined, reconnect the capacitor then connect the black AC line to the found start winding lead (marked X). Connect the white AC line to L of speed switch, the motor lead formerly connected to AC white to 3, red to 2, and white to 1 as shown below. Leave the green/yellow ground wire connection as is.

How do you wire a 240volt 1.5hp single phase electric motor that has a capaciter involved?


You don't give enough information for a specific answer. The following information generally applies. There should be a wiring diagram under one of the covers or on the metal name tag. Often there are two screw terminals inside the motor's wiring box, along with a bunch of push-on "spade" terminals used to switch the wiring for 120/240 or maybe 240/480V. The screw terminals are most likely for the power input connection. It doesn't matter which wire goes where on a single phase motor. But you need to know the motor is "set up" for the proper voltage (and rotation), which is why you need the wiring diagram. You can search for the diagram on line. The capacitor (if only one) usually connects in electrical series with the "start winding" both of these are then often switched off through a centrifugal switch once the motor is up to speed. These are then connected in parallel with the run winding(s). (Some motors have both "start" and "run" capacitors). Of the two windings, start, and run, the start winding usually has more resistance. If the motor has the ability to operate at more than one voltage this can add two more windings and up to four more wires to the puzzle, it can then be difficult to determine the proper place for all the wires if they have been removed or mis-connected. Electricity is my profession, yet I have not been able to figure out all the motor windings I've encountered while using the above information and an ohm meter. Unless you are a pro (in which case you probably wouldn't have asked this question), or if all this doesn't make sense, you might try finding a motor repair/rebuild shop near you and have them show you the proper wiring. Technically a motor this large should be installed by a licensed electrician.

LP126HD3A rated for 265 volts AC single phase I have 240V ac single phase, how can I use this unit on 240V ac


You'd need to supply a "Buck-Boost" transformer to do this properly. Technically, the 265 VAC is one hot leg and neutral of a 480 VAC 3 Phase Y system that measures 277 VAC. The 265 number comes from this:

265 is the standard nameplate voltage for a 277 volt motor or AC unit.

230 is standard name plate for 240.
200 is standard name plate for 208
460 is standard name plate for 480.
110 is standard name plate for 120.

Most electricians call the hot leg / neutral circuit "277V AC".

Some popular "Buck-Boost" transformers will convert 208 to 240 and 240 to 208 volt systems, and 240 to 277 and 277 to 240 volt systems - among many other variations. These are auto-transformers as the primary secondary windings share a connection. KVA ratings differ significantly from name plate because of this fact. You should contact a qualified electrician to not only size, but wire the transformer for you. Failure to install a Buck-Boost transformer - and running this unit on 240V AC mains will cause premature failure of motors - fans and compressor due to overheating. This can also result in a fire hazard.

I hope this helps and good luck!

I live in New Zealand which has 240 volt supply on the grid. The zantrex 2000 works with an input supply of 120 volts. How can I use it?


Hi, OK, there are two ways to achieve this. One. Using an external STEP DOWN Transformer, 240 V AC, to 120 V AC. The ONLY thing that matters is KVA. As long as the KVA is the same ir will work. This means as long as the Output Voltage and Current are the same, it's irrelevant whats on the Secondary. So if
The second, is to remove the existing transformer, and substitute with an exactly the same Secondary Outputs, BUT with a 240 V AC,. Input winding. Most likely it is a simple step Down transformer anyway, that steps down, whatever the external voltage is, down to say 12 -18 V AC. Therefor ANY suitable 240 V AC transformer with the SAME secondary winding(s) will work, no problems. You can even get some transformers Overwound, for 240 V AC, a very common thing, depending on transformer construction. There are a few transformer manufacturers in the "Yellow Pages" contact one of them and inquire.
As a tip, sometimes the existing transformer has TWO 120 V windings, and sometimes only ONE side is used, for US power, and for 240 V AC, you simply connect the other winding in series, and NOW you have got your 240 V AC to whatever.

Hello, please let me know whether I can get and fit an upgrade fan blower motor with higher ventilation capacity than the standard one ,in my Saab 900 year 1994 in order to get more passenger cooling...


As far as I know there is not one available. Seeing as the design of the actual fan is critical to the housing it would not be recommended to change it out with another fan. You may well get poorer performance What you can do however is remove the fan motor from its housing and get it to an armature winder than can modify/rewire the original fan motor to give a higher ouput. This is done by removing the old windings from the armature and using a thicker guage wire, rewiring the motor. Using stronger magnets for the field or replacing the permanent magnets with an electrmagnet type design. Unfotunately the only DIY part of this is you removing and reinstalling the unit. Rewiring is pretty specialised.

Why does a table fan slow down after some time?


Revolving blades in table fans pushes out air towards the front by creating a vacuum at the back of the induction motor. Other than providing air flow, the gush of air also cools the motor. Over time, esp if used in a polluted surrounding, dust collects inside the motor and causes friction in the shaft. If left for a prolonged period, this friction causes heat eventually drying up the lubrication, causing breakdown in the motor amature windings and also a leaky starting capacitor, thus slowing down rotation and also a complete failure.

2. Fans must be regularly taken apart, cleaned and lubricated. It is fairly easy if you are willing to learn. My India made Usha brand table fan is 48 years old and is still running smooth - just changed the start capacitor last year and my National ceiling fans are more than 35 years old.

3. In fact all moving parts in any equipment must be periodically taken apart, cleaned free of dust and grime and freshly lubricated. It will outrun your lifetime and serve the next few generations.

AC unit wong start unless I spin the blower


you have 2 windings that are in you motor,One winding is the start winding It give the motor its initial boost that gets the fan spinning.The other winding is the run winding and it takes over and keeps the fan running.So it sounds like the motor is bad because the start winding is not giving the boost it needs to start. good luck--Nate

Tips how 2 wind transformer ac -dc .output 12volts. in put 240


your windings of primary to secondary must be in a ratio of 20:1. That is, for a primary with say, 100 windings and input 240 VAC, 5 secondary windings will give you 12 VAC. you need to rectify then regulate if you want 12VDC. Just buy an off the shelf wall-wart.
