How to Test a 3 Speed Fan Motor
It can sometimes personify very disorienting to essa fan motors for people World Health Organization don't sustain much go through. This guide will hopefully make testing fan motors for you easy, regardless of your receive level operating theater type of fan motor that you are testing.
As you believably know, lover motors can personify designed for respective different purposes. Most common of these are single phase motors. Other types of fan motors, corresponding split phase and capacitor start motors, are intended for industrial environments and they are very common in factories and warehouses.
The advice mentioned here applies to every four-wire conformation fan motor, regardless of fan motor size.
Note: In this test, we use one of my favorite multimeter -- Fluke 117
Telegram configuration
In ordination to understand what wires to use of goods and services for measurement, I volition now go over the wire configuration.
Fan motors usually take in two wires; brunet and white – brown wires that are plugged into the capacitor. Other two wires are clothed and white and they are to Be plugged into the capacitor. We will test the wires reported to their functions.
!! In front you start examination, make sure that the great power is off on the sports fan motor !!
Number one drive of sports fan motor problems
One many thing before you start testing.
The top cause of fan motorial 'breakdowns' is a bad run electrical condenser. Always visually check the capacitor before you start testing because ruptured capacitors and capacitors with dents Oregon any other types of deformities are obviously broken and you postulate to replace them as presently as possible.
It goes without saying that everything is probably fine with the sports fan motor if you detect such a capacitor. I would, however, proceed with the tests just to defecate sure that there ISN't something incorrect with the fan motor because, if information technology is, it could make the unweathered capacitor break down.
How to Quiz a Fan Motor With a Multimeter
Test the first typeset of wires:
Now is the time to test the white – brown and white wires. The Patrick Victor Martindale White wire is titled the run wire.
- Take your multimeter and set it to ohms.
- Take the shameful multimeter standard test spark advance and bear upon the white wire with it.
- Touch and go on touching the white – brown wire with the ruddy multimeter probe.
Values measured in this step should be around point one or point two ohms.
If everything is Okey with the values, you can place the white – brown wire connected the face because you will not need it anymore during today's test.
Test the second set of wires:
The brown wire is the start wire and the black wire is the common wire.
- Take your multimeter and put on the negative (blackness) multimeter probe on the brown wire.
- You should put the red probe on the covered cable.
Any rate betwixt and around thirty-cardinal to 40 ohms should be well thought out as standard value.
Test the third set of wires:
- With the negative black multimeter test lead still on the browned wire, take the red try lead and take it inactive of the tweed wire.
- You volition now place the red dig into on the common wire.
Values measured in this phase of testing should Be around 15 ohms.
Test the fourth set of wires:
- Keep the red tryout lead on the total darkness wire and take the black examine away of the tweed electrify.
- Place the unfortunate dig into on the white wire.
- It is preferable to fare this test without the moving blade.
The multimeter should show values around twenty ohms.
Besides the obvious prophylactic reasons related to electricity and theory of injury, if the brand is spinning while you are trying to measure, the values will become erratic and it will be insurmountable for you to stimulate specific readings.
Tips
South-electrify clips are excellent for this kind of job.
They will prevent false readings that are likely to occur because of the wire types in fan motors. Golosh around south-wires will keep the wire strings inside.
Here is the list of succinct wire name calling reported to their function:
- The white telegraph is titled the run wire, the chocolate-brown wire is called the start wire and the black electrify is called the common wire.
- If your fan motor differs in any means to the configuration described here make sure to stick the manual and check into it for details.
- If you are still impotent to situate or key out a part necessary for testing delineated here, make certain to check down the gilded collection plate happening the fan motor. That plate contains each required information about the good example of the fan motor, manufacturer, voltage and all sorts of other important selective information that will enable you to find more info online and to test this motor with a greater muckle of knowledge and precision.
Although it was confusing at first, the stairs in this work helped me to test my fan motor, correctly diagnose the job and repair it.
If you have a multimeter, some longanimity, and good wish, it will help you to come the same.
