Hi I am new to this, being in my 60s from the UK..can any body help ..i am making a x quadcopter have bought 4 motors from Hong Kong they have three black wires from the motors ..and they are not colour coded ..can anybody help in how to connect these to the speed control ....kind regards to Everybody...Mike
Did you have bullet connectors?
If so, plug then like you want, an then try your motors and esc separately in your ch3 of your rx.
If there is one or more motors turning in the wrong side, invert two wire and try again .
Hi Thanks..i did not want to damage anything....kind regards mike
These brushless motors are essentially 3-phase motors, the ESC pulses the three wires in sequential order.
The direction they spin is down to the order of the wires.
So connect the three wires however you want, and if it spins the wrong way swap any two of them over and that will reverse the motor.
Thanks Richard too...i did not think of them as 3 phase...that answers the question thank you...kind regards Mike
No bullet connectors but i have ordered some...just other question..when trying each one separately..do you bypass the control board on the quadcopter..connect motor to esc and then connect esc direct to channel 3 on the receiver and the use channel 3 on rx to check rotation...Mike
Yes plug your esc in the 3ch of your receiver and use your tx ;) ( but without props on your motors, use some tape on your motor to see the turning side )
You can also calibrate each esc like this ^^
