Solved RESOLVED - New motor and esc always stuttering

[Coderteam1]

Guys can you please help me in this???

Simonk 30a esc
2200kv a2212 motor 6t
11.1v 2200mah battery
Servo tester

Anyways...my motor gives very high beeps on startup continuously

 

[Merv]

The continuous beeps are generally an indication there is no signal connection. If you are using a receiver, it's not bound to your transmitter. If you are using a servo tester, it's not hooked up properly, it needs to be attached to the servo end of the tester.

Make sure your servo tester is in manual mode and is turned all the way down. Most ESCs have a throttle safety so that the throttle must be off before it will arm. So if you’re trying to start it up with the throttle on, it might be warning you.

Alternately, or additionally, you may need to calibrate your throttle. In this case, turn your tester to max throttle, then plug in the ESC. It will beep several times. When it’s done, turn the throttle all the way down. It will beep several more times. Then it should be ready. You should re-do the calibration when it hook it up to your receiver.

Good luck!

Can you provide us with a picture or video of the problem? There are a lot of assumptions that can be made when guessing at a cause. Seeing the problem might help us get to the solution faster.

actually my connections are correct ( i think ) but even with calibration on transmitter idt did not work properly

batt balance plug - servo tester vin side
batt plug = esc
esc - motor
esc signal wire - servo connections
all grounds connected


anyways my problem is that my motor at max speed is moving very slowly like 100rpm then stopping for half a second then moving in another direction for half a second......


specs are

battery = 11.1v 2200mah new (full charged)
motor = generic a2212 2200kv 6t motor almost new ( used as in rotated by hand a lil bit )
esc =simonk 30a brand new



ad it does not give any wire acknowledge beeps


it should be like
beep beep beep beep beeep beeep when not connected to reciever

and

beep beep beep beep beep beep beep beeeeeeeeeep when connected to reciever

 

[Coderteam1]

and when servo tester not connected, it goes like no wire acknowledge beeps but straight to beep beep quiucklyy

@Tench745 pls see if this helps or i have to make a vid

You should not have the battery balance plug connected to the servo tester.
ESC control to the tester output.
Motor leads to to ESC output.
Battery to ESC +/-.

No, I agree with luvmy, your connections are way off. Connecting the battery balance plug to the tester is wrong and may have damaged your components.

First, you should test your servo tester and ESC for damage. Attach the main battery plug to the ESC. Attach the ESC servo lead to the input side of the tester. Finally attach a servo to the tester. If the servo works, the tester and ESC are not damaged.

The correct connection are. Connect the main battery plug to the ESC and the ECS to the motor. The only connection to the servo tester, the 3 wire servo lead from the ESC, connected to the servo side of the tester.

On the servo tester, the positive and negative pins pass though the tester, it doesn’t matter which side the power is applied.

About what luvmy40 and Merv said, you may have hooked up a single cell of your battery to the servo tester because that’s how you can provide power to the Servo tester when you’re testing servos. Using a Servo tester to test ESCs is different because the ESC’s built-in BEC is providing 5v to the servo tester through the positive (red) lead on the signal wire going from the ESC to the servo tester. By also connecting the battery directly to the servo tester, the BEC is probably trying to back feed 5v into the 3.7v battery cell. That may have burned something out, but if you’re lucky it might work fine if you disconnect the battery from the servo tester.

Could you please attach at least a picture of your setup so we can confirm how you have it hooked up? A video would be even better, but more difficult.

It never works like that

Ok attaching pic

 

[Coderteam1]

Also i think probl lies in motor as i tested it today morning and smoke was coming from motor

 

[Coderteam1]

Esc ,battery,servo tester are fine tested them

 

[Coderteam1]

This problem is with rc transmitter reciever setup also

 

[Coderteam1]

Just assume that the battery is connected

 

[Foamforce]

Ok yeah, don’t hook it up that way. You need to plug the XT60 connector from the battery to the ESC. That provides power to the ESC. The yellow/red/black wire from the ESC to the servo tester provides the 5v to the servo tester (on the red wire). The signal from the servo tester then goes back to the ESC on the yellow wire. The black wire is the common ground.

I know this is confusing because it looks like you need something attached to the input side of the servo tester, but you don’t. The positive wire is connected all the way through, so if it’s receiving power from the ESC, it doesn’t need anything on the input side. PS, I own the exact same servo tester.

Well then the motor is shot too, and it’s likely from being hooked up this way. Sorry. 😑

DON'T MAKE THIS CONECTION!
Plugging the balance lead to the servo tester is a bad mistake.
The servo wire form the ESC to the tester is all that is needed.

It’s worth clarifying our advice only applies when you’re using a servo tester to test an ESC. However, if you’re testing a servo, then it’s totally ok to hook up a single cell from your battery this way. In fact I learned that from a Flite Test video. Alternatively, you could hook up an ESC to the input to provide the power.

Here, maybe this diagram will make it clear.
