Hi all.
I bought a high speed motor from:
https://vi.aliexpress.com/item/1005...t_main.22.59bc18029ye37Y&gatewayAdapt=glo2vnm

hard to wire it to do test, what connector that may be?



Thanks
Adam

 

What is obvious is that the seller does not have any ideas as to what the mating connector ism nor does the seller care one bit if people are able to utilize that motor. There was a picture of an item represented as the driver for the motor, which might possibly include the connector. The motor is a brushless DC motor, and so it must be used with the correct driver. It should be possible to solder three wires to the solder connections we see beside the connector.

true.
seems they are selling parts for some kind of hair dryer?

 

That's a 3 phase motor

 

The ad shows it can be controlled by a an RC ESC unit!

 

Why would a motor for a high speed blower motor:
"12V 9000KV Inrunner Brushless Motor High Speed Jetfan
12V 9000KV Inrunner Brushless Motor High Speed Jetfan EDF Ducted Fan Air Blower Turbo For DIY Compressed Air Duster Cleaner"
be controlled by an RC control unit?? The ad used the "ESC" abbreviation for Electronic Speed Control, either because of being clueless or to be confusing.
In addition, observe that all of the views in that description were for a different device that had three thin wire leads, and some sort of black plastic cover over the end section.
Farther down the ad shows some electronic driver that looked to me like it plugged onto the white connector.That item is sort of visible in the third view small image we see.

To verify what I am claiming the TS needs to measure the resistances between the three pins with an ohm meter able to read low resistance with good resolution!
There is no way this motor can be controlled by an RC servo control system. That implication is an intentional mis-representation.

I don't see what there is to refute it being of RC ESC technology?

 

Thats 3 phase a brushless RC contoller would work there 3 phase

An electrical machine compliant to 60034-8 will ensure that clockwise rotation of the drive shaft will occur for positive electrical phase sequence U-V-W.

Mostly that assertion is refuted bythe seller description given in post #1.

No, you said RC servo in post #6 but that's not what it is or was called in post #1 or anywhere else. It's simple 3-phase brushless motor (per your post #2) that a RC 'ESC' could easily drive. The V-U-W marking are next to the connector.

 

OK, I am not familiar with an RC electronic speed controller. Never played with RC stuff since the HARD TUBE days.
BUT what we see is the motor portion of a BRUSHLESS DC MOTOR system, and an inadequate listing by the seller neglecting to mention that the driver is required to power that motor.
So the simple solution will be to get the driver that is intended for that motor.

 

Thank to all.
I've read and learn a lot, even my Original Intention is like to know the connector and buy one to hook it up.

I'd put another motor here instead of open a new post, that is samiliar stuff (picture may changed) I bought and the top round PCB was damaged. I am try figuluar out some thing before my new order come:

any clue about this PCB? and the wiring?
Thanks

That motor has controller made on it

yes, but damegaed.

 

It looks a lot like a very small brushless DC motor with an integrated driver board. There appear to be three driver devices, possibly "H-bridge elements", and a processor to control it all. And careless packaging caused that tiny PCB to be damaged. OR, maybe they are all damaged and that is why they are cheap.

 

It’s a esc you could find a cheap one the 3 pins in the middle are the 3 phases

get some of these

thanks.
I've ordered some, just like to try some thing before the order come. still can get any clue of that round PCB?

found a link and will try it, but the irf3205 is too large size. also there are only three wires on the motor, where to hook the VCC?
