How to Check Amp Draw on Electric Motor TUTORIAL

In that location are several reasons why it might be useful to know the amperage that your trolling motor draws while you're using it. However, getting this number might be harder than you call up.

If you lot want to discover the amperage of your trolling motor, here'due south what you need to know. Once you lot understand these things, you should be able to get the numbers yous need to brand the calculations you've been trying to make.

How To Check The Amp Draw On A Trolling Motor

Why Practice I Want to Know My Amp Draw?

There are several reasons why you might want to know the amperage draw of your trolling motor. These may not all utilise to you but you might be surprised at how useful this number tin can be.

First of all, knowing the actual amperage that your trolling motor draws can allow yous to make sure that it is working well. Compare this to the amperage that the manufacturer gives you to determine whether or not your motor is working equally it should.

Knowing this number tin can also exist useful if you lot need to take your trolling motor in for repairs. If you know the amperage draw is not what it should be, this can help a mechanic know which repairs need to be made, or at to the lowest degree what tests to run.

Knowing your amp draw will also allow you lot to accurately calculate how long your trolling motor should run off its battery. Simply dissever the amperage fatigued past the amp hours that your battery is rated for.

For instance, if your battery is rated for 100 amperage hours and your trolling motor is drawing 25 amps, divide 100 by 25 to get 4. Your trolling motor bombardment should last for iv hours.

Yous can calculate the number of amps drawn if y'all have the number of watts the motor is using. Just separate the number of watts drawn by the voltage that is powering the organization.

For instance, if your arrangement is pulling 300 watts and you accept a 12-volt trolling motor, divide 300 by 12 to get 25. This is the amperage that the motor is currently pulling. Y'all can utilize this to further calculate how long your trolling motor should last, equally outlined above.

Consult the Manufacturer

The easiest manner to become the amperage that your trolling motor draws is to wait in the transmission. You lot can too search the brand and model of the trolling motor online, along with the word "amperage", to get this number.

However, many companies only show the maximum amperage that their trolling motors draw. This number is usually the amperage at the speed highest setting.

If you don't run your motor at the highest setting all the time, or you only use that setting some of the time, calculations based on this number may exist inaccurate. Even so, the numbers you go from these calculations would be your worst-instance scenario.

If, for instance, you summate how long your trolling motor will terminal based on this amperage, then you lot know the minimum corporeality of time that it should run. Yous tin also know that you could conserve power and arrive last longer by running the gunkhole at lower speeds.

Note that this number is simply useful to y'all if your trolling motor is working well. If information technology'south having electrical issues, information technology may not be cartoon as many amps as it should be. In these cases, yous will want to endeavour to find the actual amperage rather than the platonic or tested amperage.

Use an Amp Meter

If you want to test the amperage on your trolling motor yourself, you lot'll need to buy a voltage/amperage meter. The easiest kind to apply will plug into your trolling motor on one side and your battery on the other.

Notwithstanding, you can as well apply one with contact leads. You volition just have to be more "hands-on" during the test with this meter than you would have to be with one that plugs in.

Attach the plugs to your meter or touch the negative contact lead to the negative side of your bombardment and the positive lead to the positive side. Start running your trolling motor at its everyman speed.

Go along an eye on your meter while you do this. You'll desire to brand sure you know the amperage that the motor is drawing while it is getting upwardly to speed as well as the amperage it draws when it is at full speed.

If you want to note these numbers down, do and so. This can be a good mode to test your trolling motor every once in a while to make sure it is still functioning optimally. If these numbers change, it may need a tuneup or a repair.

Change speeds on your trolling motor and follow this procedure at each speed setting. Again, make certain yous note the amperage it is cartoon while it gets upwards to speed and in one case it is going total speed.

You may demand to take an average for these numbers because the amperage draw can fluctuate 2d past second. Watch your meter to find out how often this changes for your boat and your trolling motor.

Some people cull to keep their pluggable amp meter connected all the time, merely this isn't necessary. Checking these numbers now and and so volition give you a good thought of how well your boat is working.

This video shows you how to apply an amp meter to calculate your trolling motor's amperage depict.

Conclusion

Finding the amperage depict of your trolling motor can be a claiming, but you don't demand to worry. Post-obit the instructions outlined in a higher place, yous should be able to find the numbers y'all need or to calculate them so yous tin utilise them as you need to.

Learning to find the amp describe of your trolling motor tin can be fun and it could assistance you, too. Become a more than informed angler today when you larn more almost how the electricity of your trolling motor works.
