To elaborate on @AlbertHall’s post, there is no positive and negative wire. Connect the motor’s two wires like the following.Which way round you connect them will determine which way the motor rotates.
Apart from what has been suggested, spin the motor in the original direction it was used in and measure the DC on the leads, one will be Pos, the other Neg.guys i got a dc motor from a rc car and it has 2 wires a blue one and a yellow one what do they do and which one is posotive and which one is negative???
EXACTLY! Blue and Yellow are DC motor wire colors, and the TS states that it came from a RC car, but did not say that it was a new-style one. I have several RC cars and not a single one of them has a BLDC motor. Making a statement without adequate information provides no benefit.TS says it has two wires?
Quite probably the TS is not taking a newest RC device apart. Brush type motors have been used in RC devices for at least 30 years, and so there are far more brush type motors in equipment that somebody might be taking a motor out of.All my RC airplanes that still work have brushless motors that seem to last forever.
All my RC airplanes that had the motors replaced many times had brushed motors.
All RC airplanes from Horizon Hobby that used a 1 cell Li-PO battery had brushed motors that soon wore out the brushes.
The newest RC airplane from Horizon Hobby that uses a 1 cell Li-PO battery has brushless motors.
