It’s a brushless motor, of course a brush makes it not work.

you can run multi brush motors on one esc

Thanks. Very helpful. Trying to make vtol plane with 2 edfs and now I understand how to have the same amount of current flowing through each one. Thanks again.

Thanks for the test. This confirms my concern and will steer my design another direction.

Thanks you for the video. Quite informative. From what you demonstrated, my conclusion is that using two same motors, with double sized controller should work fine. But I would use motors that use hall sensors and plugged one of them into the controller.

Nice, this explained alot. I'm working on 4x4 drive rover wheel, something like a mars rover. Maybe I will go for 1 ESC to 4 motors. this saves a lot of esc

I learned a lot from this. Thank you

very cool, thanks for taking the time to make this video.

hi, can you please help me to understand the quadcopter circuit design. should I connect the motors and other equipments in parallel or in series ?

Awesome work dude searching for this video I want this channel to become famous like others Keep it up👍👍👍👍👍👍

What would happen if you lock the shafts of the two motors together and then run from one ESC in parallel? If the kv is the same and you can somehow align the motors before locking together, would this allow both to run efficiently?

That seems to work on RC cars like the E-maxx where you sync both motors before meshing them with the spur gear. I've seen it done with 1 or 2 ESCs. I also have a Nikko rc car that has entirely separate motors and transmissions at the front and back and I've used 1 ESC and 2 brushless motors and it to work fine. Maybe a little stuttery off the line sometimes, especially a low speed start but once it was up and running it went like a dream to be honest.

@Joyplanes RC I like how you showed in the diagram at 2:35 that the signals might be out of phase. And in theory that should result in a failure, in reality it showed that is seemed just fine. this is because the ESC will try to sync then unintentionally by slowing down one motor until they are the same. This has the effect that it creates an oscillation in these signals equal to the switching frequency that will work against both motors. and this it the observed reduced efficiency as its wasting power trying to correct the errors. And although it is possible to run motors this way it is still not recommended as in the long term it will damage the ESC and/or the motor(s)

How about 2 ESCs connected to 1 motor to split the current load between the ESCs

Dc maybe, brushless won’t without some way to sync them

Ok. In spite of all my complaining. I did learn from you there is one dead pole set and two active poles. Thank you.

Well done on the video however I would like to add something. If the two motors are identical and ESC of correct rating you should not have desync issues. The two motors should phase lock (3 phase generation principle) a scope would confirm this/bl heli frames. Not advisable though.

So it can and will work just fine with no issue if your esc is double the rating? I’m making an edf car with one large brushless esc and 2 small brushless UMX motors

What if we use Universal Esc ( means an esc that can connect 4 motors ) . Will it work ?

Can you try 1 servo tester with 4 esc?

I watched earlier and found interesting, especially how one affects the other. I had an idea, isolate the motors from each other by running the one motor directly from the controller and then use the 3 phases to control the gates of 6 MOSFET,s to drive the second motor. Just a thought that came to me watching Master Chef ( don't ask) have not tried but wondering about an easy way to make my skateboard 4wd.

I have two 2200kv brushless motor and 14.8v lipo battery How to run one esc and how much amp esc is better those motors

Can someone tell me the name of the device he is using to control the speed?

One esc can used to drive two identical motors but the wires have to be very short. It works but definitely not recommended. Any differences in motors' specification, a new and an older motor, impedance due to longer or bad cables, can cause one of the motors stop or tickle due to desync.

That's good! 👍

You change direction of a brushless motor's spin by swapping out any 2 of the 3 wires. But now you need a reverse prop and you will either need to use a Left-Hand nut to secure the prop to a Left-Hand prop shaft/adapter, or use a Lock Nut or a Cotter pin thru the Right-Hand nut and shaft. Otherwise it will eventually spin the nut off the prop shaft.

Got that idea，next time i'll just connect two esc with 1 motor

A three wire esc is for a brushless motor. Brushless esc's send pulses of current to each set of windings. A 2 wire esc literally just connects the battery to the motor. A 2 wire esc at full throttle is no different than connecting the battery DIRECTLY to the motor. Google how brushless vs. brushed work.

I wanted to build a y-6 drone back then using 6 motors and 3 esc. I didn't even get the pair of motors spinning like yours lol The motors only kept on shaking but never spinned. So it's really not recommended to run multiple motors with one esc

@rubondomoralez1769

I was going to do something similar with a DJI parts drone , curious if it will work

So yes it absolutely can be done and works fine. Obviously if one motor stops the other will too. Obviously there is no redundancy for loosing a sinlgle esc if there is only one esc.

SO if you have a high amp esc and 6s normally runs 2207 1800kv double the kv at 3600kv for 6s this is a test needing to happen

Good boos

Plz add link of diagram Plz sir

The thing you say is bad ie if one motor stops so dies the other could be a good thing in a plane for a novice pilot, I saw a guy crash a twin motor model because one motor failed and he could not control the model due to to the other motor puling the plane into a spin. However I absolutely agree it's a bad idea and esc do not cost much anyway so why would you even bother risking running two motors from one esc?
